Abstract: An air-guiding element on or in a vehicle is formed of at least one fiber-reinforced composite material having a multi-layered sandwich structure. At least one of the layers of the sandwich structure is a resilient layer that consists of or comprises a material comprising an elastomer, and the layers of the sandwich structure are interconnected by a plastic matrix material.

Abstract: A method and compression mold are provided for producing a sandwich component, in which an outer shell and an inner shell are compressed, together with foam particles in a cavity between the shells, which cavity is formed by two mold halves of a mold, under pressure and at an increased temperature to form the sandwich component. At least one mold half is heated in a first temperature-control zone to a higher maximum temperature than in a second temperature-control zone.

Abstract: A method is provided in which suitable carbon-fiber scrap is fed, together with a plastic polymer, to a pulverizer and extruder in order to produce a carbon-fiber polymer mass therefrom and to impregnate the mass with a resin. A regrind prepreg, which is given suitable forms and/or lengths, is thus obtained. The regrind prepregs thus obtained can then be given an approximately final form in an additional step by way of an extrusion process.

Abstract: A molded multilayer plastics component (1) with continuously reinforced fiber plies (2, 2?), which has a sandwich structure made of an internal structure (3) made of a foam material, embedded between at least two outer plies of fiber composite plastic. Around the periphery of the embedded internal structure (3) the component (1) has a coherent edge made of the fiber composite plastic, formed through peripheral overdimensioning (2?) of at least one of the fiber plies (2, 2?) with respect to the internal structure (3). Two alternative production processes are also disclosed for producing the multilayer plastics component (1).

Abstract: The invention relates to a composite component of at least (3) different material layers, having the following layer composition: a) a carrier layer or carrier structure of metal and/or fiber-reinforced plastic, b) a bonding agent layer of elastomer, c) a cover layer of carbon fiber-reinforced or mixed carbon fiber-reinforced plastic, wherein the plastic and the arrangement of the carbon fibers or mixed carbon fibers are chosen such that the carbon fibers or mixed carbon fibers are optically visible on the surface of the cover layer.
