Laminate of aluminium sheet material and aramid fibres.

摘要

The invention relates to a laminate composed of two, three, four or more aluminium-containing metal sheets. The metal sheets (2), which may for instance be of an aluminium alloy, are bonded together by means of adhesive layers (3). In the adhesive layers, which are of a thermohardening material, there are embedded poly-paraphenylene terephthalamide threads (4). They are provided in the form of yarns made up of endless filaments, which lie in a practically straight line in the adhesive substantially consisting of a thermohardening material. The adhesive layers contain the threads in an amount of 20 to 80% by weight.
