Abstract: The tailgate (1) or rear door for a motor vehicle with a rear window includes a single-piece main carrying structure (10) with a peripheral, flexurally resistant frame (11), with an upper transverse beam (12), two lateral longitudinal beams (13, 14) and at least one lower transverse beam (15). The main carrying structure consists of a fibre-reinforced moulding compound (20) with at least two impregnated, integrated continuous-fibre bands (21) and this moulding compound is non-positively connected to the rear window (2) and together with this forms a flexurally resistant structure. Thereby, the continuous-fibre bands (21) in sections are integrated into the frame (11) in an arrangement vertical (v) to the surface (H) of the tailgate, by way of the continuous-fibre bands (21) being arranged vertically to the surface (H) and/or at a vertical distance (d) to the surface (H).

Abstract: A vehicle cell made of reinforced—reinforced thermoplastic material includes a shape-defining, long-reinforced-reinforced thermoplastic matrix (2) with integrated continuos fiber strands or strips (3). In a base structure (10), which includes a base plate (6), uninterrupted continuous fiber strands running longitudinally (3no) in an upper base area (NO) and continuous fiber strands running longitudinally (3nu) in a lower base area (NU). The upper and the lower base areas are connected with vertical walls (11). This results in an economically manufacturable, light-weight, rigid and safe vehicle cell.

Abstract: A structural component of fiber-reinforced thermoplastic material has a shape-forming long-fiber-reinforced thermoplastic matrix and separate, single load-bearing plastified and consolidated continuous fiber strands with a thermoplastic matrix in a defined position within the structural component. The positions of the shape forming long-fiber-reinforced thermoplastic matrix and the separate, single load-bearing plastified and consolidated continuous fiber strands with a thermoplastic matrix define interfaces therebetween. The continuous fiber strands are interconnected and have at least one load-transmitting flat internal connecting area between two continuous fiber strands. The single continuous fiber strands form a load-bearing supporting structure which is integrated in and thermoplastically bonded to the long-fiber-reinforced thermoplastic matrix at the interfaces therebetween.

Abstract: A supporting structure for a lightweight vehicle has a central cross tube (10) extending across the vehicle under driver's and occupant's seats. The tube has an enclosed volume formed from a floor plate (14), a top plate (11), a front wall (12) and a rear wall (13). The ends of the cross tube are fixedly attached to longitudinal support members (21, 22), forming a lightweight, rigid and safe structure. The cross-section of the central cross tube is made large (at least 15.times.25 cm) to absorb side impact forces and can contain traction power batteries which results in good weight distribution. Side rings define door openings and are rigidly attached to the cross tube and longitudinal support structure and to transverse roof struts to form a complete passenger enclosure.
