Hybridtråd til kompositmaterialer med termoplastisk matrice samt fremgangsmåde til fremstilling af denne

摘要

This hybrid yarn is of the type comprising an intimate mixture of threads of reinforcing fibres and of threads of thermoplastic matrix fibres, each of the threads of fibres having been obtained by cracking by a slow and progressive drawing of multifilaments. According to the invention, after drawing the parallel fibres (2, 3) are overwound with a continuous filament (19) of thermoplastic material. Application to the production of hot-pressed articles.
