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 () and at least one sheet () bonded to the framework. Laser cutting, CNC bending, and computer-controlled welding mean that the required production time can be kept to 120 seconds and the rigidity of the structure as a whole is sufficient. Such a chassis also has an exceptionally low carbon footprint. The sheet can be metallic, such as Aluminium or Aluminium honeycomb, or it can be a composite material such as one comprising a paper-based core and a fibre-reinforced plastics coating. 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, ideally joined by a method allowing a positional tolerance so that any tolerance in the construction of the framework can be accommodated. A corresponding method of manufacturing a chassis is also disclosed.
