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.

A process for producing a composite constructional element, said process comprising the steps of:
- forming a basic body which is made of plastic and which is provided with ribs;
- forming a reinforcing element which is either made of metal or reinforced plastic;
- either partially or completely connecting said basic body to said reinforcing element via a connection to form said composite constructional element, said composite constructional element being for transfer of any one of shearing, torsional, flexural, and tensile/compressive stresses, wherein said partially or completely connecting said basic body and said reinforcing element to form said composite constructional element takes place at a time subsequent to said forming of said basic body and said forming of said reinforcing element.
