Problems solved by technology

However, a load-bearing car shell cannot be formed in this form of construction, because it is far from reaching the necessary mechanical strength and resistance to violent impacts. Therefore, a load-bearing, stable steel frame must be used as a base component here. and supporting structures

Embodiment Construction

[0027] figure 1 The construction of a motor vehicle shell 1 according to the invention is schematically shown, which consists of a shaped, long-fiber-reinforced thermoplastic substrate 2 into which continuous fiber bundles or fiber strips 3 are integrally incorporated. The integrally joined continuous fiber bundles form a three-dimensional support structure 4 which includes a base structure 10 . In the middle of the car shell, between a front wheel suspension 8 and a rear wheel suspension 9, a long, high-strength, longitudinally arranged continuous The fiber bundles 3no, meanwhile, longitudinally arranged continuous fiber bundles 3nu are integrally added in the lower surface of the base below the axis plane 5 or in the horizontal NU. The lower surface and the upper surface of the base are connected to each other by substantially vertical shear force-transmitting wall panels 11 , and the base structure 10 is connected to the front wheel suspension 8 and the rear wheel suspensi...

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.

Description

technical field [0001] The invention relates to a motor vehicle shell made of fiber-reinforced thermoplastic and to a method for producing such a motor vehicle shell. Background technique [0002] Since significant advantages such as corrosion resistance, noise reduction and weight reduction can be achieved with fiber-reinforced plastics compared to previous metal car skins, attempts have been made to come up with a method that can be manufactured from fiber-reinforced plastics in an economical mass-production method load-bearing car shell. But this has not been realized so far, this is because the structure and manufacture of automobile shells are too complex and laborious, and therefore too expensive and time-consuming, or because simple manufacturing methods, such as short-fiber reinforced injection molding, are far from being able to achieve the desired results. High mechanical properties required. For racing cars and prototype cars, for example, the autoclaving of a b...
