<p>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.</p> |
