METHOD FOR PRODUCING FIBER-REINFORCED COMPOSITE MATERIALS FROM POLYAMIDE 6 AND COPOLYAMIDES MADE OF POLYAMIDE 6 AND POLYAMIDE 12

摘要

The present invention relates to a method for producing fiber-reinforced composite materials, by saturating a plurality of continuous filaments or woven fabrics, optionally together with reinforcement materials, containing caprolactam and other starting materials for polyamide 6, or other starting materials for copolymers of the caprolactam, passing the materials through at temperatures between 70 and 100ºC, and anionically polymerizing them at temperatures between 100 and 190ºC, and optionally re-polymerizing them at temperatures between 90 and 170ºC.
