ABSTRACT:
Apparatus for the production of high strength fiber reinforced plastic structures via an improved vacuum assisted technique. A fluid impervious outer sheet is marginally sealed upon a mold to provide an enclosure, or chamber, in which a fiber lay up can be placed. The fluid impervious outer sheet is provided with a vacuum outlet, and the mold is provided with a resin inlet. Primary distribution media are provided one located on one side of the fiber lay up and the other on the opposite side of the fiber lay up. Each is of character which facilitates on application of a vacuum the ready, continuous flow of resin via the resin inlet into the chamber to the marginal edges of said resin distribution medium and flow through of the resin through the fiber lay up.
