ABSTRACT:
A hybrid yarn is made up of an intimate mixture of spun yarns of reinforcing fibers and spun yarns of thermoplastic matrix fibers. The spun yarns are obtained by cracking with slow, gradual stretching of the multifilaments. After stretching, parallel fibers are wrapped with a continuous thermoplastic filament. The invention may be used to produce hot-stamped parts.
