Abstract
A method of manufacturing a composite material which comprises filaments enclosed in a matrix of a high temperature resistant thermoplastic polymer. The method entails impregnating the filament with a first high temperature resistant thermoplastic polymer in an amount sufficient only to lightly bind the fibres together. The bound fibres are then interposed between sheets of a second thermoplastic polymer and the whole structure subjected to heat and pressure for a time sufficient to ensure impregnation of said second thermoplastic polymer into said filaments and diffusion of the first thermoplastic polymer into the second thermoplastic polymer.
