Abstract
A hollow-chamber lightweight component is described which at least comprises a shell-shaped housing part (1) made of high-strength material. a ribbed supporting structure (2) made of plastic, in particular of thermoplastic material, and at least one cover plate (4) or covering shell (20) made of a high-strength material which is, in particular. different from plastic and a method of producing the lightweight component is described. The supporting structure (2) is up against the inside of the housing part (1) and is joined, in particular. to the housing part (1). The cover plate (4) or covering shell (20) largely covers the space formed from housing part (1) and supporting structure (2) and is joined in its peripheral region at least with one part of the boundary (10) of the housing part (1).
