Abstract
A chassis for a vehicle is disclosed which combines rigidity, speed of manufacture, and a small environmental footprint. Such a chassis comprises a framework of Interconnected tubular sections (14, 18) and at least one composite sheet (50) bonded to the framework, at least part of the composite sheet being of unidirectional fibers. The sheet can be non-flat, and is preferably a concave geometry such as a tub. It can be composed of a plurality of sections (78, 80). The part of the composite sheet that Is of unidirectional fibers extends obliquely rearwardly from a tubular section on one side of the chassis toward a further tubular section on another side of the chassis, the fibers also being oriented obliquely rearwardly In the same sense. A further similar part extends in the opposite direction/symmetrically, overlapping as necessary.
