Reinforced thermoplastic component e.g. for motor vehicle interior load-bearing panel has main body and reinforcing elements of same or compatible thermoplastics

摘要

The component consists of a main body (1) comprising a first thermoplastic matrix, and at least one reinforcing element (2) of a material comprising a second thermoplastic matrix with continuous parallel fibres. The first and second matrices are of the same or compatible thermoplastics welded together or made in one piece. The reinforcing elements are in the form of elongated profiles with glass, mineral, vegetable or synthetic fibres lying parallel to their axes and making up 20 - 80 per cent of their weight. They have a Young modulus at 23 degrees C of between 10000 and 50000 MPa and a permitted stress of between 200 and 900 MPa.
