Abstract: The invention concerns a vehicle wheel, comprising a body of a plastics material and at least one adapter for fastening the body to a wheel mounting, the at least one adapter having at least one protuberance which engages in a recess in the body, or, if multiple adapters are used, at least one adapter is formed such that it engages in a recess of the body over its full surface area, the adapter being arranged in such a way that, after assembly of the body on the wheel mounting, the adapter is positioned between the body and the wheel mounting, or the adapter being arranged in such a way that the body is positioned between the wheel mounting and the adapter, so that the adapter lies on the outside of the body after assembly.

Abstract: A structure for absorbing energy from impacts thereon, the structure being plastically deformable by an impact, with, if appropriate, the possibility that it is at least to some extent disrupted. The structure can include a) ribs for reinforcement, the ribs arranged with respect to one another at an angle with respect to the axial direction such that on failure of a rib a force acting on the structure is immediately absorbed axially by another rib, b) ribs running axially, the ribs being in essence corrugated or of zigzag shape, c) at least one rib running axially in a first plane and connected to at least two ribs running axially in a second plane rotated with respect to the first plane. The structure includes, in the direction of impact, at least two layers, each of which has different compressibility properties and different failure properties.

Abstract: The invention relates to a wheel for a motor vehicle, comprising a wheel body (3) with a rim tape (7) for receiving a tire and a rim star (9) or a wheel disk, through-holes (13) for receiving fastening means (17) of the wheel body (3) on a vehicle axle being formed in the rim star or in the wheel disk. The wheel body (3) is produced from a reinforced polymer material and is connected non-positively, positively or integrally to a cap (5), the cap (5) covering the rim star (9) or the wheel disk. Furthermore, the invention also relates to a process for producing the wheel.

Abstract: The invention concerns a vehicle wheel, comprising a rim (1) of a plastics material and at least one adapter (5) for fastening the rim (1) to a wheel mounting (3), the at least one adapter (5) having at least one protuberance (9) which engages in a recess (11) in the rim (1), or, if multiple adapters (5) are used, at least one adapter (5) is formed such that it engages in a recess (11) of the rim over its full surface area, the adapter (5) being arranged in such a way that, after assembly of the rim (1) on the wheel mounting (3), the adapter (5) is positioned between the rim (1) and the wheel mounting (3), or the adapter (5) being arranged in such a way that the rim (1) is positioned between the wheel mounting (3) and the adapter (5), so that the adapter (5) lies on the outside of the rim (1) after assembly.

Abstract: The present invention relates to binders for the preforming process to which textile structures are subjected when structural materials are produced by the RIM or RTM method, where the binder composed of an amorphous polyimide is spray applied in a solvent onto the textile structure or onto the textile, and is used as binder for the preforming process. The present invention further relates to a process for producing moldings made of fiber-reinforced composite materials.

Abstract: Process for producing fiber-reinforced composite materials, by a) molding a textile structure and then spray-applying a binder, or saturating the textile structure with a binder, or b) first spray-applying a binder to a textile structure, or saturating a textile structure with a binder, and then subjecting the material to forming and drying.
