Title
(EN) FIBER-REINFORCED COMPOSITE MATERIAL
(FR) MATÉRIAU COMPOSITE RENFORCÉ PAR DES FIBRES

Abstract
(EN)
According to a fiber-reinforced composite material (11) of the present invention, a laminated fiber bundle layer is formed by laminating a plurality of fiber bundle layers formed of a reinforced fiber, and furthermore a matrix is impregnated in the laminated fiber bundle layer. At either side of a neutral surface (16), the number of +θ fiber bundle layers which have a fiber orientation angle of +θ is the same as the number of -θ fiber bundle layers which have a fiber orientation angle of -θ. The order of laminating the fiber bundle layers is inversely symmetrical to a standard surface, and the number of other fiber bundle layers disposed between each of the +θ and -θ layers at both sides by the standard surface is the same.

La présente invention porte sur un matériau composite renforcé par des fibres (11), dans lequel matériau une couche de faisceaux de fibres stratifiée est formée par stratification d'une pluralité de couches de faisceaux de fibres constituées par une fibre de renfort, et, de plus, il est réalisé une imprégnation d'une matrice dans la couche de faisceaux de fibres stratifiées. De chaque côté d'une surface neutre (16), le nombre de couches de faisceaux de fibres +θ qui ont un angle d'orientation de fibre de +θ est le même que le nombre de couches de faisceaux de fibres -θ qui ont un angle d'orientation de fibre de -θ. L'ordre de stratification des couches de faisceaux de fibres est inversement symétrique par rapport à une surface standard, et le nombre d'autres couches de faisceaux de fibres disposées entre chacune des couches +θ et -θ des deux côtés vis-à-vis de la surface standard est le même.

 繊維強化複合材料(11)は、強化繊維からなる複数の繊維束層を積層して積層繊維束層を形成し、更に積層繊維束層にマトリックスを含浸させることにより構成されている。また、中立面(16)を挟む両側のそれぞれで繊維配向角度が+θの繊維束層である+θ層の数と、繊維配向角度が-θの繊維束層である-θ層の数とが同じであり、繊維束層の積層順は基準面に対して逆対称であり、基準面を挟む両側のそれぞれにおける+θ層と-θ層との間に配置される他の繊維束層の数が同じである。
