Method of manufacturing a plastic tank with reinforcements
A method for producing a plastic tank having one or more reinforcements. The method includes forming at least one part of the tank wall with a semi-finished panel made of plastic having at least one outer layer composed of a first thermoplastic, forming a reinforcement for the tank wall with at least one fibre-reinforced structural component comprising a matrix composed of a second thermoplastic that is weldable to the first thermoplastic. The fibre-reinforced structural component is then applied to a predefined region of the at least one outer layer of the semi-finished panel. The fibre-reinforced structural component is then fused with the outer layer of the semi-finished panel by applying heat to the semi-finished panel and the applied fibre-reinforced structural component. The fused fibre-reinforced structural component and semi-finished panel is then formed into a final shape. Optionally, the formed component is then connected to at least one other part of the tank wall to form the complete tank wall.
RESIN SHEET HAVING HAIR-LIKE BODIES AND MOLDED ARTICLE THEREOF
A resin sheet having: a surface layer having hair-like bodies arranged regularly on one surface thereof; and a second layer directly laminated to a surface opposite that of the hair-like bodies of the surface layer, the surface layer comprising a thermoplastic polyurethane resin and the second layer comprising a polymer alloy resin of a polycarbonate-based resin and a polyester-based and resin.
PLANAR COMPOSITE MATERIAL
A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fiber web or a thermoplastic film, and at least two unidirectional oriented-fiber layers B and B′, the layers B and B′ having a bidirectional fiber orientation. The layers are not only needled but also stitched to one another.
Method For Producing a Moldable, Thermoplastic, Continuous Fiber Reinforced Composite Structure, Moldable Composite Structure, and Device For Producing Same
The invention is characterized by a semifinished composite structure product with the at least two layers, of which the at least one layer, in which the continuous fibers are contained, is heated such that the matrix of thermoplastic material is heated within at least one first surface region to or above a melting temperature that can be assigned to the thermoplastic material, and the matrix of thermoplastic material is kept to a temperature below the melting temperature within a second surface region directly adjoining the first surface region. The semifinished composite structure product is heated in this way so that the moldable thermoplastic, continuous fiber-reinforced composite structure in which the continuous fibers within the first surface region are movable relative to each other and those within the second surface region are spatially fixed relative to each other.

Method for manufacturing a heating mat for a motor vehicle
A method for manufacturing a heating mat for a motor vehicle. The method includes the following steps: providing a heating ply having a deformable structure and two heating elements inserted into the structure, said two heating elements being separated by a deformation area of the structure; stacking the heating ply between an upper layer and a lower layer, wherein at least one of the heating ply and the upper and lower layers includes a thermoformable material; assembling the stack by at least one fastening rod; and thermoforming the stack thus assembled, so as to secure the heating ply and the upper and lower layers into a single piece; and stretching the deformation area in the stacking direction.
Method and apparatus for deep-drawing a tray from sheet material
The invention relates to a method and an apparatus for deep-drawing a tray (1) from fiber-based sheet material (2), such as polymer coated board. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger plate (11) for forming the tray bottom inwardly, the plunger plate being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is provided for free forming of the tray side walls while wrinkling or tearing of the same is avoided. Spacer plates (13) may be positioned behind the plunger plate (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) there below, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.
DEEP-DRAWN SEGMENT
A method for producing a water-tight, water-vapour-permeable segment, having a three-dimensional contour, for a shoe shaft, an item of clothing or a rucksack or for producing a shoe shaft, an item of clothing or a rucksack, the segment being free of connection points in its surface, and the method for producing the segment being a thermoforming process in which the two-dimensional flat structure obtained is completely laminated in its entirety, the segment being free of connection points in its surface. Also, a water-tight, water-vapour-permeable segment of a three-dimensional functional laminate for introduction into a shoe or shoe shaft, an item of clothing or a rucksack, the segment being dimensionally stable under its own weight, of a single piece and free of connection points in its surface.
Systems and methods for thermoplastic panel stretch/roll forming
A thermoforming method includes forming a skin comprising a plurality of plies thermoplastic resin and fiber, securing an edge of the skin to a mandrel, heating, via a heating element, the skin to a forming temperature, moving a thermoforming apparatus with respect to the mandrel, rolling at least one roller of the thermoforming apparatus along the skin in a direction away from the clamped edge of the skin in response to the thermoforming apparatus moving with respect to the mandrel, and in response to the at least one roller of the thermoforming apparatus rolling along the skin, compressing the skin between the at least one roller and the mandrel, consolidating the plurality of plies of material, and bending the skin to conform to a shape of the mandrel. The consolidated and formed skin is then cooled and removed from the mandrel.
