Abstract

On forme par aiguilletage ou par liage thermique une natte (4) constituée d'écheveaux de fibres (1) qui contiennent des fibres de verre (1) et des fibres (2) de matières thermoplastiques. On façonne avec cette natte sous l'effet de la pression et de la chaleur un corps composite (7) qui contient des fibres de verre (1) dans une matrice homogène (8) de matière thermoplastique. Ce corps composite peut à son tour être façonné pour former des éléments en matière plastique renforcée par des fibres de verre.
