DETAILED DESCRIPTION

[0055] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0056] Organo sheet is a fiber composite material, typically in the form of a semifinished fiber-matrix product. In the case of such a fiber composite material, (reinforcing) fibers are embedded in a plastic, typically in a thermoplastic or thermosetting plastic. Here, the fibers can be embedded in particular in the form of laid scrims, woven fabrics, knitted fabrics or so-called UD tapes (that is to say unidirectional tapes) composed of glass, Kevlar, carbon or plastic fibers, that is to say in particular carbon, aramid or natural fibers, in a thermoplastic or thermoset matrix. Examples of suitable thermoplastic for the matrix are polypropylene (PP) or polyamide (PA) on account of the good adhesive properties with respect to the fibers. The embedded fibers are frequently continuous fibers, and so a continuous-fiber-reinforced plastic is also spoken of.

[0057] The characterization “continuous-fiber-reinforced” is understood to mean that the length of the fibers serving for reinforcement is limited substantially by the size of a typically plate-like organo sheet. Within the organo sheet, a fiber is generally not interrupted.

[0058] The fact that the carrier region is substantially formed by organo sheet means in this case that the organo sheet forms that part of the carrier region which is subjected to the majority of the forces occurring under normal operating conditions. Here, this may in particular be that part of the carrier region on which one or more guide rails of a window regulator are provided. A part (which for example bears one or more guide rails or which integrally forms at least one guide rail and is coherent) of the carrier region composed of organo sheet or a plurality of parts (which for example bear one or more guide rails or which integrally form at least one guide rail) of the carrier region composed of organo sheet extend for example over approximately 30% or more of the area of the carrier region. In particular, the organo sheet can extend over more than 40% and generally over at least 50% of the area of the carrier region, and therefore the organo sheet thus also forms a corresponding proportion of more than 40% or approximately 50% or more of the surface of the carrier region. In order to fully utilize the strength advantages of the organo sheet, attempts are generally made to maximize the proportion of the organo sheet on the area of the carrier region. A multi-part configuration of the organo sheet on a carrier region is not ruled out here.

[0059] A main constituent of the door module is for example a plate-like semifinished product composed of an organo sheet. The organo sheet thus for example defines a substantial areal extent of the door module, but can also be supplemented by further components or materials. By way of example, it is thus possible for metallic elements and/or plastic elements to be incorporated in the organo sheet or attached to the organo sheet.

[0060] Particularly in the automotive sector, and here for example for the production of vehicle doors, organo sheet is nowadays already used in different forms. Here, provision is typically made for merely the carrier region of a door module to be at least partially manufactured from a particular type of organo sheet and plastic material, for example for the formation of interfaces, to be injection-molded thereon. The organo sheet with the plastic material injection-molded thereon is then frequently covered by cladding components which are additionally provided on a vehicle door.

[0061] FIG. 1 shows an exploded illustration of a vehicle door T, in the case of which a door module 1 forming a window frame FR is assembled on a bodyshell assembly which is referred to hereinafter as bodyshell R. The bodyshell R typically comprises a door outer skin and a door inner skin which is rigidly connected thereto. The bodyshell R defines a wet space for accommodating functional components of the vehicle door T, said wet space being sealingly separated from a dry space facing toward the vehicle interior by way of a carrier area 10 of the door module 1.

[0062] Different functional components of the vehicle door T, for example components of a window regulator, a speaker and/or components of a door lock, are fixed to the carrier area 10, which extends beneath a window sill B of the assembled vehicle door T in accordance with FIGS. 2A and 2B. Further functional components can for example be sensors which are to be provided on or in the vehicle door T. By way of example, in FIG. 12, guide rails 2A and 2B and a drive A, as functional components of the window regulator, are arranged on the carrier area 10, specifically on an outer side of the carrier area 10, said outer side facing toward the door outer skin of the bodyshell R. An inner cladding part I, which covers the carrier area 10 in the assembled state of the vehicle door, is provided on the side of the interior.

[0063] In the present case, the door module 1, which in FIGS. 2A and 2B is illustrated in two different side views in its state assembled on the bodyshell R, is produced from organo sheet, and thus in one-piece form from a fiber composite material. This applies in particular for the window frame FR which extends above the window sill B and which borders a window opening O on the vehicle door T. A connection between the bodyshell R and the door module 1 is effected for example by way of screw connections. Alternatively or additionally, at least one rivet connection and/or an adhesive connection can be provided.

[0064] In the case of the door module 1 illustrated in FIGS. 2A and 2B, at least in one portion of the window frame FR which extends above the sill B, there is no panel provided for covering an organo sheet of the door module 1 in said region. Rather, provision is made here for a frame region 12 of the door module 1, said region at least partially forming the window frame FR, to be covered, at least on its side facing toward the vehicle interior, by injection-molded plastic material in such a way that at least one part of a visible decorative surface of the finished vehicle door T is formed thereby. Here, at least one portion of a decorative surface of the vehicle door T in the region of the window frame FR is consequently formed, on the door module side, by the injection-molded plastic material.

[0065] The frame region 12 is illustrated in particular in FIG. 3, which schematically shows a side view of the vehicle door 1 with the door module 1 assembled on the bodyshell R. In addition to the areal carrier region 10 which is provided beneath the window sill B and the frame region 12 which extends above the window sill B and defines the window frame FR, the door module 1 in this case also has a reinforcing region 11 in the region of a mirror triangle and directly adjacent to the window sill B. In this case, the reinforcing region which is elongate here consequently extends along a door-module-side sill region.

[0066] In the design variant illustrated, different types of organo sheets are used in the three regions 10, 11 and 12 of the door module. The different types of organo sheets, which are combined with one another here in the door module 1, in this case permit a function-specific design of the different regions 10, 11 and 12 in a comparatively simple manner. The individual regions 10, 11 and 12 can for example be formed with blanks made from different organo sheets. The different types of organo sheets differ here with regard to their material thickness. However, the organo sheet types can additionally also differ from one another with regard to the materials of their reinforcing fibers, the alignment of the reinforcing fibers and/or the number of fiber layers present. In this way, a laminate is formed from partially overlapping individual layers, in the case of which the layer thicknesses of the organo sheets used differ from one another in the respective regions 10, 11 and 12 by way of load-appropriate selection.

[0067] Here, the organo sheets can in principle each have a thermoplastic, but also thermoset matrix and be optionally reinforced with at least one metallic insert. By way of example, polypropylene (PP) or polyamide (PA) is used for the thermoplastic matrix. Reinforcing fibers of the respective organo sheets are for example composed from glass, carbon or aramid. Alternatively or additionally, natural fibers can also be used.

[0068] In the design variant illustrated, an organo sheet having a single-layered woven fabric or single-layered laid scrim is used for example for the carrier region 10, wherein the organo sheet has a material thickness in the range from 0.4 mm to 1 mm, for example in the range of 0.6 mm here. In the reinforcing region 11 which is close to the sill, a multi-layered woven fabric or laid scrim is provided, and also a material thickness in the range from 0.9 mm to 4 mm, for example in the range from 1 mm to 1.5 mm. A material thickness in the range from 1.8 mm to 4 mm, in particular in the range from 2 mm to 2.5 mm, is in turn provided in the frame region 12, wherein the fibers here are aligned unidirectionally to a comparatively great extent. The individual regions 10, 11 and 12 are thus of differing thickness and formed with a different number of fiber layers. Moreover, in the reinforcing region 11, there is at least one continuous overlap provided either with at least one portion of the carrier region 10 or with a portion of the frame region 12 (for example in the region of the mirror triangle).

[0069] Correspondingly to the enlarged illustration of FIG. 4, the use of different types of organo sheets means different types of organo sheets bear against one another and on top of one another at node regions K, and also plastic material is applied in particular to such node regions K, for example for the formation of an injection-molded portion 120 for a part of a frame-side decorative surface. This is to be taken into account in the production method of the door module 1.

[0070] The structure of the door module 1 and its production are illustrated with further details on the basis of FIGS. 5A to 14. For the sake of simplicity and for better identifiability of individual details, the door module 1 is illustrated here in each case only in sections in the manner of a so-called demonstrator module, and therefore merely a section of the frame region 12, a section of the frame region 11 and a section of the areal carrier region 10 are evident in each case here. Correspondingly, in FIGS. 5A to 14, the door module 1 is illustrated merely at maximum with a length a and a width b, which correspond in each case to a fraction of the total length and the total width, respectively, of the door module 1 in its finished shape.

[0071] FIGS. 5A and 5B show the door module 1 in its state when connected as intended to the bodyshell R, looking at an inner side and an outer side of the vehicle door T. From this, in particular in conjunction with the individual illustrations of FIGS. 6, 7A and 7B, it is evident that the regions 10, 11 and 12 of the door module 1 are formed with different blanks of organo sheets of different types. Whereas a blank for the reinforcing region 11 in this case completely overlaps an edge, which is close to the sill, of the blank provided for the carrier region 10, there is merely a partial overlap provided between the blank for the frame region 12 and the blank for the carrier region 10 in order to ensure a connection of the blanks on the finished door module 1.

[0072] Plastic material is in each case injection-molded onto the blanks of organo sheets for the formation of the individual regions 10, 11 and 12. Injection-molded sections and overmolded sections of the individual blanks can be produced from different plastic materials here. Alternatively, different elements and regions can be formed by a plastic material, such as, for example, PP LGF 30, by means of injection molding on the (organo sheet) blanks.

[0073] By way of example, an injection-molded portion 101 is thus provided on the door module 1, fastening openings being formed on the edge side of the respective regions 10, 11 and 12 by way of said portion. The door module 1 is fixed to the door inner skin of the bodyshell R by way of the fastening openings of the injection-molded portion 101. At least some of the edge-side fastening openings formed on the injection-molded portion 101 can also be used for fixing functional components to the door module 1. Reinforcing ribs 100 which are injection-molded with the plastic material are also shaped on an inner side of the carrier area 10 of the door module in order to at least locally stiffen the carrier region 10 and/or in order to locally stiffen any fastening openings.

[0074] An injection-molded portion 120 is also formed on the inner side of the frame region 12 by way of the plastic material, said injection-molded portion forming a part of a frame-side decorative surface. In this case, for example a portion of a decorative surface with a grained visual appearance is then formed by way of the injection-molded portion 120 composed of plastic material which is injection-molded onto the frame region 12, and therefore separate paneling is no longer required at least over a part of the frame region 12 (see in particular FIG. 7A).

[0075] On an outer side of the door module 1, correspondingly to FIG. 7B, reinforcing ribs are likewise formed by way of an injection-molded portion 121 on the frame region 12. The reinforcing region 11 is also reinforced by way of an injection-molded portion 110 with reinforcing ribs. On the outer side illustrated in FIG. 7B, it is also possible for a part of a guide rail 2A, 2B, or alternatively a bearing point at least for a guide rail 2A, 2B of the window regulator, to be shaped by way of an injection-molded portion 102 on the carrier region 10.

[0076] The door module 1 illustrated is distinguished by the use of organo sheets of differing thickness which are formed onto one another and patched, and which are first thermoformed in a shaping tool in order to form the door module 1. After the shaping by means of the tool, an injection-molding function is performed in the same tool in order to form interfaces, functional regions (such as, for example, the guide rails 2A, 2B in the injection-molded portion 102) and stiffening ribs. Details relating to design variants of a production method are illustrated on the basis of FIGS. 8A to 14 which are explained below.

[0077] FIGS. 8A and 8B thus initially show the door module 1 of FIGS. 6 to 7B without the plastic material injection-molded thereon, looking at the outer side (FIG. 8A) and the inner side (FIG. 8B). In FIGS. 8A and 8B, blanks Z1, Z2 and Z3 with which the functionally and spatially separated regions 10, 11 and 12 of the door module 1 are formed are highlighted in this case. Here, a first blank Z1 is composed of an organo sheet of a first type having a material thickness in the range of 0.6 mm. The blank Z1 in this case has merely one fiber layer, for example. A second blank Z2 is composed of an organo sheet of a second type for the formation of the frame region 12. The organo sheet of the second type for the second blank Z2 for the frame region 12 has several (at least two) fiber layers, in particular possibly a UD tape, and also a material thickness in the range from 2.0 mm to 2.5 mm with a comparatively great unidirectional fiber alignment. A third blank Z3 for the reinforcing region 11 is composed of an organo sheet of a third type and can likewise have several fiber layers. A material thickness of the organo sheet of the third type in this case lies in the range from 1 mm to 1.5 mm.

[0078] In the design variant illustrated, provision can in principle be made for the reinforcing fibers for all three blanks Z1, Z2 and Z3 to in each case be provided in single-layered or multi-layered woven fabrics, laid scrims, knitted fabrics or in UD tapes and to be configured in the form of glass fibers in a thermoplastic matrix.

[0079] Correspondingly to the exploded illustration of FIG. 9, the individual blanks Z1, Z2 and Z3 are first produced separately from the different types of organo sheets and then used to form the door module 1 by means of a shaping tool W (see FIG. 13).

[0080] In the case of a production method which is illustrated in exemplary fashion on the basis of the flow diagram of FIG. 10, a process sequence is then for example provided as follows:

[0081] 1. First, the areal blank Z1 which substantially forms the carrier region 10 is heated, specifically above the actual (forming) tool WZ which is sketched in an exemplary and schematic manner in FIGS. 12 and 13.

[0082] 2. The blanks Z2 and Z3 are subsequently heated in a heating station, for example a horizontal heating station.

[0083] 3. The blanks Z2 and Z3 are subsequently transferred into the tool WZ, for example by means of a needle gripper.

[0084] 4. In this case, the blanks Z2 and Z3 are attached to a fixed tool side WZa of the tool WZ and needle-mounted on needles N of the tool WZ.

[0085] 5. The blanks Z2 and Z3 are then pre-draped inside the tool WZ. For the frame region 12, on which the injection-molded portion 120 for forming a part of a frame-side decorative surface is injection-molded, the blank Z2 in particular is pre-draped in a manner which is as true to the final contour as possible. In order to pre-drape the blanks in a manner which is true to the final contour, contact to the tool WZ is provided over as large an area as possible, in particular in order to achieve comparatively great cooling prior to the overmolding with plastic material. Elsewhere, the pre-draping of the blanks in a manner which is close to the final contour may be sufficient. By way of example, merely draping of the blanks Z2 and Z3 in a manner which is close to the final contour is required in an overlap region of the blanks Z2 and Z3. Here, there is correspondingly only pointwise contact made with the tool WZ for slower cooling.

[0086] 6. Whereas a manufacturing machine was fully open for the introduction and needle-mounting of the blanks Z2 and Z3 in the tool WZ and the pre-draping of the blanks Z2 and Z3, said machine is subsequently transferred into an intermediate position. In this intermediate position, the blank Z1 for forming the carrier area 10 is introduced into the tool WZ.

[0087] 7. Subsequently, the tool WZ is closed and the injection-molding process is carried out in order to shape the individual injection-molded portions 100, 101, 102, 110, 120 and 121 on the blanks Z1, Z2 and Z3 of the different types of organo sheets, said blanks being arranged in the forming tool WZ.

[0088] In the context of the proposed design variant, the blanks Z2 and Z3 having greater material thickness, which therefore have a higher heat capacity, are consequently arranged on the tool WZ at an earlier stage and pre-formed, before a blank Z1 made from a thinner organo sheet is transported into the tool WZ. In this case, in addition to the manufacturing machine which receives the tool WZ, the blanks Z2 and Z3 can already be formed in a suitable station at forming temperature. Such a heating station for example has an IR emitter or a circulating air oven.

[0089] In the context of the transfer of the blanks Z2 and Z3 into the tool WZ, the blanks can be already preformed and at least partially consolidated. Here, a handling system provided for the transfer can then simultaneously be used as a preformer, for example. Once the handling system has been moved out of the tool WZ after the preforming and the arrangement of the blanks Z2 and Z3 in the tool WZ have been completed, the thinner blank Z1 is introduced into the tool WZ. In this case, the thinner blank Z1 has been heated for example above a cavity of the tool WZ, for example above an IR emitter field. In this connection, provision can also be made that it is necessary for merely a linear displacement into the tool WZ to be carried out in order to supply the thinner blank Z1.

[0090] In the design variant illustrated, during the production process the blank Z2 is in particular pre-draped on those subregions of the frame region 12 which are highlighted with I. and II. in FIG. 11. In the subregion I. on which the covered part of the frame region 12 is generated by way of injection-molded plastic material, complete consolidation may be carried out in order to ensure complete overmolding with the plastic material, for example PP LGF 30 here. There is also no overlapping join of two blanks in said subregion, and therefore the surface temperature does not predominate for the process times and the overmolding of the relatively cold organo sheet blank Z2 for the visual graining to be provided by way of the injection-molded plastic material makes process-reliable conditions possible.

[0091] By contrast, in the subregion II., pre-draping with pronounced embossing of the blank Z2 takes place in a manner which is close to the final contour. Here, a relatively large process window is consequently available, since slower cooling takes place without tool contact.

[0092] FIGS. 12 and 13 show further details for the production process. In said figures, it is in particular possible to see needles N which are configured on a fixed tool side WZa of the tool WZ and on which the blanks Z1, Z2 and Z3 made from organo sheet—for example the blank Z2 provided for the frame region 12 in FIGS. 12 and 13—can be needle-mounted in order to fix the corresponding blank on the tool WZ. In principle, corresponding needles N could in this case also be provided on an opposite tool side WZb, but are not illustrated in FIG. 13.

[0093] During the fixing of the blanks Z1, Z2 and/or Z3 to the tool WZ, the needles N can also be used to generate passage openings on the respective blank. In particular, such passage openings can be generated in overlap regions of at least two blanks Z1 to Z3. Plastic material can then be introduced through said passage openings of a plurality of blanks Z1 to Z3, said openings then at least partially overlapping, and therefore portions of the blanks Z1 to Z3 which lie on top of one another in the overlap region have the injection-molded plastic material injected therethrough and are thereby fixed to one another in a positively locking manner when the plastic material is cured. By means of the plastic material which is injected through the passage openings, it is consequently possible for the blanks Z1 to Z3 to be “riveted” to one another by way of the plastic material.

[0094] In this connection, FIG. 14 shows possible nozzle positions D1 and D2 for the plastic material to be injected. In addition, an advancing slide region VB is illustrated in FIG. 14. At said advancing slide region VB, the tool WZ can be used to realize a local preforming operation which runs ahead of the actual shaping operation. In the advancing slide region VB, in which an overlap region of a plurality of blanks Z1 to Z3 is also provided, it is for example possible for slight overpressing by 0.1 mm to 0.2 mm to take place.

[0095] In a deviation from the design variant illustrated, it is of course possible for the door module 1 to have merely two different types of organo sheet or more than three different types of organo sheets, which are connected to one another to form the door module and are optionally fixed to one another by way of injection-molded plastic material. In this case, the different types of organo sheets can differ from one another not only with regard to their material thickness and the number of fiber layers present but also by the materials of their reinforcing fibers and/or alignment of said reinforcing fibers.
