Process for manufacturing composite articles and composite articles obtained

Abstract

Abstract Process for manufacturing finished articles consisting of continuous reinforcing fibres connected together by a thermoplastic matrix, characterised in that it comprises the following steps: - introducing particles of thermoplastic powder into the core of a continuous roving of fibres; - covering the said roving by means of a layer of plastic whose melting point is below that of the powder particles and by operating at temperatures such that the imprisoned powder particles cannot melt and continue to flow freely between the fibres; - stacking the flexible profiles thus obtained in several layers so as to produce the desired shape of the finished articles; - heat-treating the stack obtained; - cooling and solidifying. Application to the manufacture of components by filament winding, pressing and reinforcement of moulded components.
