<p>The invention relates to a laminate composed of two, three, four or more aluminum-containing metal sheets. The metal sheets, which may for instance be of an aluminum alloy, are bonded together by means of adhesive layers. In the adhesive layers, which are of a thermohardening material, there are embedded poly-paraphenylene terephthalamide threads. These threads are provided in the form of yarns made up of endless filaments and lie in a practically straight line in the adhesive which substantially consists of a thermohardening material. The adhesive layers contain the threads in an amount of 20 to 80% by weight.</p> |
