A method for fabricating fiber reinforced plastic structures includes a mold surface upon which can be supported a lay-up of one or more layers of a fibrous material, and over which can be placed a fluid impervious outer sheet with an inlet port and having its edges marginally sealed upon the mold surface to form a chamber. A vacuum outlet is connected to the chamber for drawing a vacuum there from. A resin distribution system is positioned between the lay-up and the fluid impervious sheet. The resin distribution system includes a resin distribution medium for receiving resin from the inlet port and a resin containment layer between the resin distribution medium and lay-up for preventing resin flowing from the resin distribution medium into the lay-up until the resin distribution medium is substantially filled with resin.
