Abstract
The invention is an apparatus for forming fiber reinforced resin structures In detail, invention includes a fluid impervious outer first sheet. A mold surface is includes upon which can be supported a lay-up of at least one layer of fibrous material, and over which can be placed the first fluid impervious outer sheet and its edges marginally sealed upon the mold surface to form a chamber. A first vacuum port for drawing a vacuum upon the chamber is located in proximity to the lay-up. A first distribution medium is positioned between the fabric lay-up and the fluid impervious outer sheet for distributing resin into the lay-up. A second fluid impervious sheet is located between the first distribution medium and the first impervious sheet. A resin inlet port extends from the exterior of the chamber through the first and second impervious sheets an is in communication with the first distribution medium. A second distribution medium is located between the first and second impervious sheets for providing a flow path from the lay-up to the outlet port. A second vacuum port extends from the exterior of the first impervious sheet to the chamber and in communication with the second distribut…
