DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0063] In a flowchart, FIG. 1 shows the individual steps of a method according to a preferred embodiment or an alternative, respectively, for producing a load-bearing tool component 1.

[0064] In a first step S1, as start of the method, PBO fibers 4 (ZYLON® HM) as fiber components as well as epoxy resin as thermosetting matrix component 8 of a matrix system 6 are selected for a fiber-plastics composite 2 (see FIG. 2). Thereafter, the method progresses into a step S2, in which the matrix system 6 is provided. The matrix system 6 thereby has epoxy resin as a (thermosetting) matrix component 8. The matrix system 6 can thereby have only epoxy resin as thermosetting matrix component 8, but also further matrix components, such as, for instance, vinyl ester resin or unsaturated polyester resins.

[0065] Step S2, providing the matrix system 6, comprises a step S2.1, providing a carrier film 10 (see FIG. 2) as well as a step S2.2, in which the unhardened matrix system 6 is applied to the carrier film 10.

[0066] The step S3, compiling PBO fibers with length distribution adapted to the field of use, takes place after the step S2. In this step S3, at least one PBO fiber roving 11 with circular or ellipsoidal/elliptical cross section is initially provided in a (first sub-)step S3.1. A (PBO fiber) roving is understood to be a bundle of parallel (PBO) fibers in the form of continuous fibers. The PBO fiber roving 11 is thereby unwound from a coil (not illustrated). So-called primary fibers and no recycled secondary fibers are used thereby. In a step S3.2, this PBO fiber roving 11 is thereafter formed into a strip-shaped PBO fiber roving 11′, which is as flat as possible, in order to attain the best possible fiber-matrix bond without disadvantageous hollow spaces, as described below. For example, the PBO fiber roving 11 can be guided via discharge devices and deflection rollers and can be fanned out as widely as possible. So as not to attain any continuous PBO fibers, the flat, strip-shaped PBO fiber roving 11′ is trimmed into PBO fiber cuttings 12 (see FIG. 3) of predetermined length distribution in a step S3.3. In this context, the term length distribution refers to the proportionate distribution of the present lengths of the PBO fibers, in the case of which the PBO fibers can be at hand of equal length (share of the single length in the length distribution is 100%, a single “peak”) or of a different length (trimmed) (at least two different lengths with respective shares of below 100%). One could also say that the length distribution is a function over the length, the value of which reflects the share of the length, wherein the sum of the share is 100%. In the event that the PBO fibers have different lengths, the length distribution can have, for example, exactly two or more defined, different lengths of PBO fibers. The length distribution can also be a normal distribution of the length of the PBO fibers by a maximum of a certain length. Together with optionally further fibers, these PBO fiber cuttings 12 form a fiber mixture. In addition to the PBO fiber cuttings 12, the fiber mixture can have further fibers, such as, for instance, carbon fibers. The fiber mixture can in particular have only the plurality of PBO fiber cuttings 12 of a single predetermined length.

[0067] In a step S4, the fiber mixture with the PBO fiber cuttings 12 is then lastly added to the matrix system 6. This takes place in a defined manner by means of a step S4.1, dripping of the fiber mixture with the PBO fiber cuttings 12 in a quantity, which is adapted to the field of use, onto a matrix layer 14 of the matrix system 6. A fiber layer 16 with (at least) the PBO fiber cuttings 12, which bears on the matrix layer 14 of the matrix system 6 and which optionally protrudes into said matrix layer and penetrates into the latter, is thus created. A volume share of the PBO fibers 4 in the fiber-plastics composite 2 can also be adjusted via the quantity, which is adapted to the field of use.

[0068] To embed the PBO fibers 4 or the PBO fiber cuttings 12, respectively, into the matrix system 6 primarily completely, the application of a further matrix layer 14 of the matrix system 6 onto the fiber layer 16 takes place in a step S5. To produce a semi-finished product 18, which can also be handled well and which does not adhere in particular to system components during further processing, a further carrier film 10 is applied to the applied further matrix layer 14 in a step S6. A sandwich configuration thus results as the semi-finished product 18 consisting of carrier film 10, matrix layer 14, fiber layer 16, matrix layer 14, and carrier layer 10, in the case of which the fiber layer 16 is placed symmetrically between the other layers and is in particular embedded. The matrix layers 14 form the thermosetting plastic matrix 8.

[0069] In a subsequent step S7, the semi-finished product 18 produced in this way is compacted and in particular flex-levelled by means of a compacting unit. In this state, the produced semi-finished product 18 can be handled, in particular stored, transported, shaped, in particular trimmed, torn, or bent. Several layers of the semi-finished product 18 can also be placed one on top of the other or stacked one on top of the other in layers, wherein the carrier films 10 between the layers are in each case removed.

[0070] After the carrier films 10 have been removed, the compacted semi-finished product 18 is subsequently fed to a heatable (heating press) mold, in particular placed into said mold, which presses the semi-finished product 18 in a positive manner and thus brings it into its final shape, heats up and hardens by means of the press heating process, in order to lastly demold the tool component 1 according to the invention in the design of a fiber-plastics-composite press-molded part. The viscosity of the matrix system 6 thereby initially decreases strongly under the high pressure and the high temperature, and allows for a (partial) flowing of the matrix system 6. In this state, the PBO fibers 4 are wetted completely by the matrix system 6, or the PBO fibers 4 have a direct contact with the matrix system 6, respectively, if possible on all surfaces. Shortly afterwards, the matrix system 6 reacts with associated increase of its viscosity and hardens.

[0071] In a last step S9, the press-molded tool component 1 is lastly removed from the heatable mold and can be used in a chip-removing tool.

[0072] In a perspective view, FIG. 2 shows a (manufacturing) method according to the invention or an SMC system 20 (Sheet-Molding-Compound System 20), respectively, which is adapted to a method according to the invention, for producing the semi-finished product 18 for the fiber-plastics-composite tool component 1 according to the invention according to a further, second preferred embodiment. This second embodiment/alternative of the method is a subset of the first embodiment, wherein the steps S8 and S9 are not used, because only the semi-finished product 18 is produced for a later processing.

[0073] Concretely, FIG. 2 shows the SMC system 20, in the case of which a carrier film 10 in the form of a PE cover film is unwound and is fed to the further method stations (see arrow for direction of movement) on a conveyor belt 22 (step S2.1). The matrix system 6 or the matrix layer 14, respectively, is applied or squeegeed, respectively, to the carrier film 10, which is transported onward by means of the conveyor belt 22, by means of a squeegee unit 24, to the carrier film 10 (step S2.2). The matrix system 6 is (at least partially) provided thereby (step S2).

[0074] Above the squeegee unit 24, the flat, strip-shaped PBO fiber rovings 11′ run parallel and in the same direction as the conveyor belt 22, running side by side. These strip-shaped, parallel PBO fiber rovings 11′ are fed to a cutting device 26, which cuts them into the desired length. After the cutting, the PBO fiber roving 11′ disintegrates loosely into individual fibers, adhere to one another electrostatically and which form the flat PBO fiber cuttings 12. Even though a partial falling apart of the PBO fibers 4 in the PBO fiber cuttings 12 is possible, it hardly takes place. In this embodiment, these PBO fiber cuttings 12 form the fiber mixture. The cut PBO fiber cuttings 12 fall in an unoriented manner onto the epoxy resin film, which forms the matrix layer 14 of the matrix system 6, and are thus dripped on (step S4.1). A fiber content or a volume share, respectively, of the PBO fibers 4 in the fiber-plastics composite 2 can be adjusted via the web speed of the conveyor belt 22.

[0075] The fiber layer 16 applied in this way on the matrix layer 14 and the carrier film 10 is transported onward by means of the conveyor belt 22, and a further carrier film 10, to the underside of which a further matrix layer 14 of the matrix system 6 is applied with the help of a further squeegee unit 24, covers the fiber layer 16 (steps S5 and S6). A semi-finished product 18 is now present as web, in the case of which the fiber layer 16 is surrounded by the matrix layers 14.

[0076] This semi-finished product 18 is guided through downstream a rolling mill 28, where the matrix system 6 or the two matrix layers 14, respectively, with the PBO fibers 4 or the fiber layer 16, respectively, are flex-levelled into one another, in order to connect the two layers 14, 16 to one another well, in order to embed the PBO fibers 4 into the matrix system 6 as well as possible, and in order to reduce possible hollow spaces of air inclusions or of fiber shares, which are too small, and to avoid them completely, if possible. The semi-finished product 18 in web-shape is wound onto rolls at defined weights and is stored for several days until reaching the thickening depth. This semi-finished product 18 as SMC molding compound (Sheet Molding Compound) can then in particular be trimmed, so that an SMC molding compound, which is adapted to the heatable mold, is molded.

[0077] In a partial view, FIG. 3 shows a schematic top view onto the fiber layer 16, in which the PBO fiber cuttings 12 are located one on top of the other in an unordered manner and form layers. Ideally, a PBO fiber cutting 12 has a thickness of exactly one fiber of the PBO fiber 4, or the thickness corresponds to the diameter of an individual PBO fiber 4 of approx. 10 μm, respectively. An approximately even and high fiber share or volume share, respectively, of the PBO fibers 4 is thus attained.

[0078] FIGS. 4 and 5 in each case show a scanning electron microscope (SEM) image with two different magnification levels. The two FIGS. 4 and 5 show a polished section of a fiber-plastics-composite layer 2 produced according to the method, wherein the plane of the polished section lies parallel to the PBO fibers 4. This plane is also drawn in schematically in FIG. 11 with the description “sectional plane parallel to the PBO fiber”. The SEM image thus corresponds to a top view onto the individual layers of the fiber-plastics composite 2, as it is suggested, for instance, in FIG. 3. An individual PBO fiber cutting 12, seen in FIG. 4 on the left-hand side, is surrounded roughly with a dashed line. It can be seen clearly in FIGS. 4 and 5 that the individual, flat PBO fiber cuttings 12 only have few PBO fibers 4 one on top of the other in a direction perpendicular into the side plane, or a thickness of only a few PBO fibers 4, respectively. A PBO fiber cutting 12 has in particular fewer than ten layers of PBO fibers 4 in the direction of its smallest extension. In FIG. 5, which is the fivefold magnification of the fiber-plastics composite 2 from FIG. 4, a line parallel to the PBO fibers 4 is drawn in in the center. Along this line, viewed starting from the top right, leading to the bottom left in FIG. 5, a first layer of PBO fibers 4 can be seen, which is provided with the designation (1). A second, third, fourth, and fifth layer are in each case identified with (2), (3), (4), and (5). This PBO cutting 12 thus only has five layers of PBO fibers 4, viewed into the side plane. The frayed ends of the PBO fibers 4 originate from the polished section for the SEM image, in the case of which the surface was polished off to be flat. Bright regions represent the matrix system 6, whereas the dark, fiber-shaped regions represent the PBO fibers 4.

[0079] FIGS. 6 and 7 likewise show a scanning electron microscope image of a polished section of a fiber-plastics-composite layer 2 produced according to the method in two different magnifications, wherein, this time, the plane of the polished section lies perpendicular to the PBO fibers 4. In other words, FIGS. 6 and 7 in each case show a cross sectional view of the hardened fiber-plastics composite 2, wherein the (sectional) plane is shown schematically in FIG. 11 with the description “sectional plane perpendicular to the PBO fiber”. For example, elliptical cross sections of the PBO fibers 4 show that these cut-off PBO fibers 4 have a different orientation in the plane, in which the PBO fibers 4 of a layer are located, than, for example, the PBO fibers 4 with circular cross section. It can also be seen that the volume share of the PBO fibers 4 is higher than the volume share of the matrix system 6.

[0080] FIG. 8 shows a schematic longitudinal sectional view through the semi-finished product 18, which was produced by means of the above-described SMC system 20. A layered composite of the carrier film 10, the matrix layer 14, the fiber layer 16, the matrix layer 14, and the carrier film 10, can be seen, which is present after the step S6, applying the carrier film 10. The layers 10, 14, 16 of the layered composite bear loosely one on top of the other and have not been compacted yet.

[0081] In a schematic detail view, FIG. 9 shows a magnified partial section, which is suggested with the ellipsis in FIG. 8, essentially through the fiber layer 16 of the layered composite of the semi-finished product 18 from FIG. 8. The introduced PBO fiber cuttings 12 are not yet completely embedded in the matrix layers 14 at some points, but air inclusions 34 are still present, which have a negative impact on a bonding of the matrix system 6 with the PBO fibers 4 or the PBO fiber cuttings 12, respectively. Surfaces of the PBO fiber cuttings 12 are thus present, which are not in direct contact with the matrix layers 14. To attain an embedding, which is as complete as possible, of the PBO fiber cuttings 12, the step S7, compacting of the semi-finished product 18 follows, in which the semi-finished product 18 is compacted and the PBO fibers 4 are flex-levelled into the matrix system 6.

[0082] FIG. 10 shows a longitudinal sectional view through the semi-finished product 18 after the step S7, compacting, during which the semi-finished product 18 comprising the fiber-plastics composite 2 was flex-leveled by means of the rolling mill/the compacting unit 28. The two oppositely directed arrows thereby suggest the applied pressing force of the press rolls.

[0083] In a schematic detail view, FIG. 11 shows, identical to FIG. 9, the magnified partial section, which is suggested in FIG. 10 with an ellipsis, through the fiber layer 16 of the layered composite of the semi-finished product 18 from FIG. 10, after the steps S7, compacting, and S8, pressing, heating, and hardening of the semi-finished product 18 in the heatable mold (not illustrated). The thickness (dimensions in FIGS. 8 to 11, viewed in the vertical direction) of the semi-finished product 18 was reduced on the one hand, the air inclusions 34 were removed on the other hand.

[0084] Schematically, FIG. 12 shows a side view of the semi-finished product 18, which was press-molded into the final fiber-plastics-composite tool component 1 after the step S8, pressing, heating, and hardening of the semi-finished product 18 in a heatable mold (not illustrated).

[0085] In a cross sectional view through the PBO fiber roving 11, FIG. 13 shows in a schematic manner the step S3.2 forming the PBO fiber roving 11 with elliptical cross section into a flat, strip-shaped PBO fiber roving 11′ with the smallest possible thickness (the thickness with approximately two fiber diameters is illustrated schematically in FIG. 13). The thickness of the strip-shaped PBO fiber roving 11′ is thereby defined as the distance of the side surfaces, viewed in the vertical direction, in FIG. 13. When cut off, the PBO fiber cuttings 12 then likewise result with the smallest possible thickness.

[0086] FIG. 14 shows a top view onto a tool component 1 according to the invention of a preferred embodiment in the form of a carrier plate with plate-shaped basic structure 36. The PBO fiber cuttings 12, which are located one on top of the other and which are embedded in the matrix system 6, can be seen, which are located in a plane (in FIG. 14 identified with plane E here) in an undirected manner and which thus effect a two-dimensional isotropic material property of the tool component 1. The tool component 1 is formed from several layers of the pressed and hardened semi-finished product 18, in order to attain a necessary thickness (seen in FIG. 14 the dimension perpendicular into the side plane/figure sheet plane or perpendicular to the plane E, respectively) and stiffness of the carrier plate, and in order to absorb the mechanical stresses.

[0087] FIG. 15 shows the tool component 1, which was produced from the carrier plate shown in FIG. 14, wherein the tool component 1 in the form of the carrier plate is inserted into a chip-removing rotary tool 38 comprising a modulus-like base body or modulus-like carrier, respectively. The tool component 1 is thereby fastened to a clamping portion 42 as well as to carrier portions 44 by means of screws 40 in the axial direction. The carrier portions 44, which carry cutters 46, the clamping portion 42, here in the form of a hollow shaft cone receptacle, and/or a carrier plate 48 fastened on the front side, can have the fiber-plastics composite 2 with the PBO fibers 4 as material, or can consist completely of the fiber-plastics composite 2. The entire rotary tool 38, optionally except for smaller elements, such as, for instance, the screw 40, the cutter 46, or cutter inserts, can be constructed from the fiber-plastics composite 2. Due to the fact that the weight of the rotary tool 38 with a large diameter is low, a clamping portion 42 with a small diameter can be used. This allows for the use on a spindle with a small diameter, as it is currently used in the case of machine tools.

[0088] Any disclosure in connection with the method according to the invention for producing a fiber-plastics-composite tool component also applies for the load-bearing tool component according to the invention, and any disclosure in connection with the load-bearing tool component according to the invention also applies for the method according to the invention.

[0089] It goes without saying that deviations from the above-described embodiments are possible, without leaving the basic idea of the invention. For example, the production method of the fiber-plastics composite can differ from the described alternative to the effect that the fiber-plastics composite is produced in 3D printing (additive manufacturing), wherein the fibers are embedded in the matrix to be printed, for example as continuous fibers or continuous fiber rovings, respectively. The fibers are thereby placed in such a way by means of a positioning device that they are implemented in the component or the tool component, respectively, during the matrix discharge or plastic discharge, respectively, directly by means of the discharged plastic. For example, fiber-plastics-composite tool components can thus be manufactured additively from granulate with continuous fibers. The tool components can thus be applied layer by layer of the finest plastic drops with the help of a special nozzle onto a movable component carrier, and can thus be constructed to form 3D components.
