Elements of continuous-fibre-reinforced moulding compositions based on polyamide and rubber, and process for preparing them.

摘要

1. Structural components of roving-reinforced polyamide moulding materials and rubber and process for their production. …2.1 The object of the present invention was to provide rigid but nevertheless resilient composite elements having good vibration-damping properties, in which the individual parts can be firmly bonded to one another without the use of adhesion promoters. …2.2. According to the invention, the desired combinations of properties can be realised in structural components of at least two moulding materials A and B firmly bonded to one another, where … …  a) the moulding material A consists of a roving-reinforced polyamide-containing moulding material and …  b) the moulding material B is the rubber obtained after vulcanisation of a rubber composition applied to A and containing a rubber which contains carboxyl or anhydride groups. … …2.3. The structural components are suitable for all purposes in which a combination of high rigidity and high resilience is required, for example for flank protection elements in vehicle construction or for armour plating.
