  • the plastic base body can be tightly wrapped with other fibers in the form of a fiber bundle, a so-called roving.
  • the thread tension of the wrapped rovings can be so high that they can constrict into the unidirectionally fiber-reinforced plastic base body, as a result of which defects in the fiber bundle of the plastic base body can occur.

L'invention concerne un procédé de fabrication d'un profilé en matière plastique (1) profilé au moins par endroits et renforcé par des fibres, comprenant les étapes suivantes : la fourniture de plusieurs premières fibres de renforcement (2), de préférence des fibres longues et/ou des fibres continues ; l'amenée des premières fibres de renforcement (2) à une unité (3) destinée à réunir les premières fibres de renforcement (2) et à produire un faisceau de fibres (4) uni, bi ou tridirectionnel ; l'amenée du faisceau de fibres (4) à une unité (5) destinée à imprégner le faisceau de fibres (4) d'une première matrice de matière plastique ; l'amenée du faisceau de fibres (4) imprégné à une unité (7) destinée à au moins en partie mettre en forme et à au moins en partie ou entièrement faire durcir la première matrice de matière plastique de manière à produire un corps de base en matière plastique (8) renforcé par des fibres, en particulier sous l'effet de la chaleur ; la fourniture de deuxièmes fibres de renforcement (9) destinées à être appliquées au moins par endroits sur le corps de base en matière plastique (8) renforcé par des fibres ; l'amenée du corps de base en matière plastique (8) renforcé par des fibres et pourvu des deuxièmes fibres de renforcement (9) à une unité (13) de profilage au moins en partie renforcé par des fibres et/ou de mise en forme de manière à produire un boudin de matière plastique (14) au moins en partie profilé, renforcé par des fibres (14), en particulier sous l'effet d'une pression ; le rognage du boudin de matière plastique (14) profilé au moins par endroits et renforcé par des fibres de manière à produire un profilé en matière plastique (1) profilé au moins par endroits et renforcé par des fibres.
