Claim Text:
1. An apparatus for manufacturing a composite, comprising: a volumetrically restraining body structure that defines a cavity; a bottom release layer disposed within said cavity of said volumetrically restraining body structure, wherein said bottom release layer supports a cast material deposited on said bottom release layer; an air bag disposed between said bottom release layer and one or more surfaces of said volumetrically restraining body structure within said cavity, wherein one or more surfaces of said air bag are composed of a flexible metal sheet surfaced with a silicone coating; an air compressor connected to said air bag for pressurizing said air bag, wherein said pressurized air bag compresses said deposited cast material against said bottom release layer; one or more resin inlets disposed on said deposited cast material for infusing resin into said deposited cast material; and a vacuum outlet insertably connected in said cavity of said volumetrically restraining body structure, in communication with said deposited cast material, for drawing a vacuum through said deposited cast material and for drawing said resin from said one or more resin inlets into said deposited cast material; whereby said compression of said deposited cast material by said pressurized air bag reduces excessive resin rich areas in said composite created from said deposited cast material infused with said resin.
