Laminaat met plaatselijke versterking.

摘要

A laminate of metal layers and plastic bonding layers situated between the metal layers includes two external metal layers extending substantially continuously and at least one internal metal layer. At least one of the internal metal layers has at least one opening, and at the position of the opening the other metal layers and plastic bonding layers are bonded together to the form of a packet of lower thickness. The relatively thick parts of the laminate can be used for the transfer of forces.
