An apparatus for use in the production of fiber reinforced polymer composite structures includes a mold having a mold surface and a fiber construction on the mold surface including at least one layer of resin absorbing fibrous lay up material. A stiffener on the fiber construction is constructed of a resin absorbing material. A flexible, resin impervious vacuum bag lays over the mold surface and is marginally sealed to the mold surface to define an enclosure for the fiber construction and stiffener. The vacuum bag has a resin inlet to permit introduction of a resin into the enclosure. A vacuum is drawn upon the enclosure to draw the vacuum bag against the fiber construction and stiffener. The stiffener spaces the vacuum bag from the fiber construction when the vacuum bag is drawn against the fiber construction and stiffener to facilitate the distribution of resin uniformly throughout the fiber construction. The stiffener is integrated with the fiber construction upon curing of the resin.

[ What is claimed is:] [1.] An apparatus for use in the production of fiber reinforced polymer composite structures, the apparatus comprising:a mold having a mold surface,a fiber construction on the mold surface comprising at least one layer of dry resin absorbing fibrous lay up material,a stiffener on the fiber construction, the stiffener being generally constructed of a dry resin absorbing material,a flexible, resin impervious vacuum bag over the mold surface, the vacuum bag being marginally sealed to the mold surface to define an enclosure, the fiber construction and stiffener being generally within the enclosure, the vacuum bag having a resin inlet to permit introduction of a resin into the enclosure, andmeans for drawing a vacuum upon the enclosure to draw the vacuum bag against the fiber construction and stiffener,the stiffener spacing the vacuum bag from the fiber construction to facilitate the distribution of resin uniformly throughout the fiber construction when the vacuum bag is drawn against the fiber construction and stiffener, the stiffener being integrated with the fiber construction upon curing of the resin.
