CA 2468952

A fiber-reinforced composite material comprised of reinforcing fibers and a matrix resin, wherein at least some of the reinforcing fibers have their ends in the matrix resin, characterizes in that a second resin having an elastic modulus less than that of the matrix resin is present in contact with fiber ends of at least some of reinforcing fibers having above-mentioned ends and only in the neighborhood thereof.

L'invention concerne un matériau composite à fibres comprenant des fibres de renforcement et une résine matricielle. Au moins quelques unes desdites fibres de renforcement ont leurs extrémités dans ladite résine matricielle et se caractérisent par le fait qu'une seconde résine ayant un module élastique inférieur à celui de ladite résine matricielle est présente en contact avec les extrémités d'au moins quelques unes des fibres de renforcement ayant les extrémités susmentionnées et seulement dans leur voisinage.
