Textile reinforcements for composite materials and method of manufacturing thereof

摘要: From 3 to 25 g/m2, in particular from 5 10 g/m2 of a pulverulent reactive hot-melt composition including prepolymer and hardener for the latter are applied onto one or two faces textile reinforcement. The becomes active only at temperature above that which powder softens become tacky. This on makes it possible preform reinforcement before is employed manufacture an article made composite material.
