Abstract: A composite member for a vehicle body a method for manufacturing such a composite member, in particular, for a vehicle roof, with a fiber-free outer skin (12) and a fiber-reinforced support layer (16), which is deposited at the inner side of the outer skin in order to support the outer skin. The side of the support layer (16) that faces away from the outer skin (12) is provided with a fiber-reinforced reinforcing layer (18) for reinforcing the support layer. The reinforcing layer has a higher fiber concentration than the support layer.

Abstract: The invention relates to a process for producing a composite component, with the following steps: separate producing a decorative composite made of at least one backing layer and of at least one colorant layer, separate producing a structural composite made of at least one outer layer and of at least one spacer confected thereto, introducing a connecting layer between decorative composite and structural composite, and joining of the structural composite and of the decorative composite together with hardening of the connecting layer.

Abstract: A roof module for motor vehicles is disclosed having an exterior skin, a material layer adjacent thereto, a spacer layer, and a circumferential plastic material.

Abstract: The invention relates to a device and a process for the preparation of polyurethane composite materials reinforced by fibers or solid particles, comprising at least one PUR spray-mixing head with a defined spraying direction and at least one application means for the directional application of fibers and/or solid particles, characterized in that the exiting direction of the fibers and/or solid particles can be changed in space relative to the spraying direction of the PUR spray-mixing head.

Abstract: The invention relates to a process for the production of fiber-reinforced composite components in which an outer film is bonded with a layer containing fiber-reinforced polyurethane, characterised in that a) first an elastic intermediate layer which has a modulus of elasticity of 0.5 MPa to 50 MPa and a thickness of 0.3 mm to 6 mm, is applied to the outer film which has a thickness in the range of 0.2 mm to 5 mm, and then b) at least one other layer is applied to the back of the intermediate layer, at least one layer containing fiber-reinforced polyurethane being applied.

Abstract: The present invention relates to composite elements constructed from an outer layer (i), a fiber-reinforced polyurethane (PU) material which contains in-mold release additives as a supporting layer (ii), and optionally, a decorative inner layer (iii). This invention also relates to suitable processes for the production of these composite elements and to body components comprising these composite elements.

Abstract: Processes comprising: providing a mold; providing an insert having a shape such that it fits exactly into the mold, and applying one or more layers selected from top coats and films (A) to the insert; placing the insert into the mold; introducing a polyurethane reactive mixture (D) into the insert; curing the polyurethane reactive mixture to form a polyurethane molding; and removing the polyurethane molding and insert from the mold.
