HEAT RESISTANT SEMI-AROMATIC POLYAMIDE COMPOSITE STRUCTURES AND PROCESSES FOR THEIR PREPARATION.

摘要

The present invention relates to the field of composite structures and processes for making them, particularly it relates to the field of heat resistant polyamide composite structures. The composite structure has a surface having at least a portion made of a surface resin composition and comprises a fibrous material selected from non-woven structures, textiles, fibrous battings and combinations thereof, which is impregnated with a matrix resin composition. The surface resin composition and the matrix resin composition are made of a polyamide composition comprising a) one or more polyamide resins selected from semi-aromatic polyamide resins and b) one or more polyhydric alcohols having more than two hydroxyl groups.
