Apparatus and method for selectively distributing and controlling a means for impregnation of fibrous articles

A method for the production of fiber-reinforced resin structures comprising

• creating a fiber containing preform having desired dimensions and properties;
• placing a fluid impervious flexible sheet containing a resin port therein on said fiber reinforced preform and sealing it around said fiber containing preform so as to form a chamber containing said preform;
• positioning a resin channeling means on said fluid impervious flexible sheet, exterior to said chamber;
• forming a pocket between or around said resin channeling means and said fluid impervious flexible sheet to which a vacuum may be applied;
• applying a secondary vacuum to said pocket so as cause formation of channels on said fluid impervious flexible sheet;
• activating a primary vacuum to said chamber containing said fiber containing preform;
• infusing resin into said chamber containing said fiber-containing preform via said resin port;
• deactivating said secondary vacuum when said fiber containing preform has been impregnated with resin as desired so as to eliminate said channels formed;
• curing said resin-containing preform;
• deactivating said primary vacuum when said curing is complete;
• and
• removing said fluid impervious flexible sheet from said cured, resin containing preform.
