Abstract
Textile reinforcing material useful for producing composite laminated articles by a general injection-molding technique, which is fabricated by arranging a stack of layers having textile reinforcements in a mold of a shape corresponding to that of the article to be fabricated and, after the mold has been closed, injecting a resin into it. At least one layer of the stack of textile reinforcements has a structure in which ducts extend in at least one direction therein to facilitate the flow of the resin during injection.
