Abstract

A method of manufacturing a composite material in which layers of reinforcing filaments are stitched across with filaments of a thermoplastic polymer and then interposed between sheets of the same thermoplastic polymer as that used to stitch across the reinforcing filaments. The resultant stack is then heated under pressure for sufficient time for the thermoplastic polymer to impregnate the reinforcing filaments whereupon the thus formed composite is cooled under compression in order to avoid any distortion thereof.
