Abstract

A composite material includes a metallic bottom flat element, a metallic top flat element, and an intermediate layer made of a thermosetting synthetic material and arranged between the bottom flat element and the top flat element. The intermediate layer includes three or more duromers, with at least one of the duromers being in a cured state and the other ones of the duromers being in an uncured state. The at least one of the duromers has a polymerization temperature between 50 and 100° C., with a second one of the other ones of the duromers having a polymerization temperature between 170 and 220° C. and a third one of the other ones of the duromers having a polymerization temperature between 230 and 260° C.
