<p>A chassis(10) for a vehicle Is disclosed which combines rigidity, speed of manufacture, and an small environmental footprint. Such a chassis(10) comprises a framework(20) of interconnected tubular sections(10,12,14,16,18,20) and at least one sheet(50) bonded to the framework. Such a chassis(10) 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(50) 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.</p> |
