Reinforcing material, for e.g. skis, is made from glass, carbon or synthetic filaments, coated with thermoplastic and joined by fusion

摘要

Reinforcing material (1) is based on crossing layers (2, 4) of parallel filaments (3, 5) of glass, carbon or synthetic materials with a volume of 30-600 dtex. The filaments are coated with a thermoplastic material at a rate of 10-500 g per 1000 m and joined by localized fusion of the coating. Reinforcing material (1) is based on crossing layers (2, 4) of parallel filaments (3, 5) of glass, carbon or synthetic materials with a volume of 30-600 dtex. The filaments are coated with a thermoplastic material at a rate of 10-500 g per 1000 m and joined by localized fusion of the coating. The filaments in the first layer (2) can be volumized or texturized, or coated with an anti-unraveling thermoplastic powder. A variant can have a third layer of parallel filaments laid across the other two.
