  • Patent number: 4942013
    Abstract: A process and system for vacuum impregnation of a fiber reinforcement, such as carbon cloth, with a resin to produce a resin-fiber composite. Liquid resin enters in arrangement or system comprising a fiber reinforcement layer on a tool or mold and is directed via a system of flow paths to impregnate the fiber reinforcement layer uniformly across the width thereof and along the length of the fiber reinforcement layer. According to one embodiment, a fiber reinforcement layer, e.g., carbon cloth, is placed on a tool. A porous paring film is applied over the fiber reinforcement layer and a bleeder layer, e.g., fiberglass, is applied over the parting film. A non-pourous film is placed over the bleeder layer, a breather cloth, e.g., fiberglass, is then applied over the non-porous film, and a vacuum bag is placed over the entire assembly and sealed to the mold surface. Liquid resin is fed to the assembly within the vacuum bag. Resin spreader means, e.g.
