Abstract:
A method for the production of fiber-reinforced resin structures comprisingcreating 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.
