Abstract

A process for producing a composite constructional element from a basic body made of plastic which is provided with ribs and is partially or completely connected to a reinforcing element made of metal or reinforced plastic. In this process, the connection of the basic body and reinforcing element to form the composite constructional element for the transfer of shearing, torsional, flexural and tensile/compressive stresses takes place at a subsequent time in a separate work step.
