  • Patent number: 5702663
    Abstract: An vacuum bag for forming of a fiber reinforced composite article, made of a curable elastomer, having molded in resin distribution means. Optional vacuum conduits are molded into the periphery of the bag, causing the bag to be adapted to any number of mold shapes. The bag contains a resin distribution conduit sealed into the vacuum bag. A multiplicity of cross channels are formed on the inner surface of the bag, covering most of the area under which the fiber lay up is placed within the mold. These cross channels can be formed from a pattern of multiple, variegated small dots or pentagons, which, under vacuum, leave a multiplicity of small crisscross channels running along the inner surface of the vacuum bag. This pattern of distribution channels covers most of the fiber lay up, except for a perimeter area which insures resin flow into rather than across the fiber lay up.

  • Patent number: 5316462
    Abstract: An unitary vacuum bag for forming of a fiber reinforced composite article, made of a curable elastomer, having molded in resin distribution means formed to the specific article to be made. Optional vacuum conduits are molded into the periphery of the bag, causing the bag to be adapted to any number of mold shapes. The vacuum bag is constructed upon that mold which forms the base for the construction of the desired fiber reinforced composite article. The bag contains an open sided, resilient main distribution conduit running laterally along the long axes of the vacuum bag with branch conduits, depending upon the shape of the mold, to provide for long distance flow of resin to all parts of the composite article. A multiplicity of cross channels are formed on the inner surface of the bag, covering most of the area under which the fiber lay up is placed within the mold.
