Patent

CA 2647466

The invention relates to a web-like or sheet-like semi-finished product capable of forming a polymeric foam composite material by heat treatment, which semi-finished product is formed by a web-like or sheet-like fibrous material and a mixture comprising curable resin and unexpanded thermoplastic particles of at least two different qualities with mutually different expansion temperature introduced into the fibrous material, wherein thermoplastic particles of at least one of said qualities remain unexpanded in the semi-finished product. The invention also relates to a polymeric foam composite material formed by such a semi-finished product. Furthermore, the invention relates to methods for producing such a semi-finished product and such a polymeric foam composite material.

La présente invention concerne un produit semi-fini de type toile ou de type feuille capable de former un matériau composite de mousse polymère par traitement thermique, lequel produit semi-fini est formé par un matériau fibreux de type toile ou de type feuille et d'un mélange comprenant une résine durcissable et des particules thermoplastiques non expansées d'au moins deux qualités différentes avec une température d'expansion mutuellement différente introduit dans le matériau fibreux, les particules thermoplastiques d'au moins une desdites qualités demeurant non expansées dans le produit semi-fini. La présente invention concerne également un matériau composite de mousse polymère formé par un tel produit semi-fini. En outre, l'invention concerne des procédés de production d'un tel produit semi-fini et d'un tel matériau composite de mousse polymère.
