CA 2760968

A method for manufacturing a composite material member is provided with a step of shaping, in accordance with a die, a laminated body wherein prepreg sheets are laminated.  The laminated body includes a first layer wherein fibers are arranged in one direction.  In the first layer, a first surface intersecting with such direction and a second surface intersecting with such direction face each other.  Since the fibers are discontinuous between the first surface and the second surface, the laminated body is easily shaped, and wrinkles are not easily generated on the composite material member manufactured by using the laminated body as a material.

L'invention concerne un procédé de fabrication d'un élément en matériau composite qui consiste à former, selon une matrice, un corps stratifié dans lequel des feuilles préimprégnées sont stratifiées. Le corps stratifié comporte une première touche dans laquelle des fibres sont disposées dans une direction. Dans la première couche, une première surface s'entrecoupant avec une telle direction et une seconde surface s'entrecoupant avec une telle direction se faisant face. Etant donné que les fibres sont discontinues entre la première surface et la seconde surface, le corps stratifié est aisément formé, et des plis ne sont pas facilement générés sur l'élément en matériau composite fabriqué à l'aide du corps stratifié utilisé comme matériau.
