Abstract

Feuille composite (48) consituée d'une résine moulable et de fibres de renforcement. La résine est une résine thermoplastique, une résine thermodurcissable ou un mélange des deux et les fibres de renforcement sont des fibres centrifugées par un défibreur à processus rotatif, ladite feuille composite comprenant au moins 5 couches distinctes de fibres de renforcement par millimètre d'épaisseur. La feuille composite compte au moins dix couches distinctes de fibres de renforcement et de préférence au moins 30 couches distinctes. Au moins 85 % des fibres de renforcement sont des monofilaments et les fibres de renforcement sont des fibres de laine de verre.
