ABSTRACT:
A method for making a fiber reinforced composite article includes placing in a forming mold article cavity a preform which includes at least a fiber reinforcement arrangement, such as stacked piles of resin bonded sheets. Closure of the mold defines a matrix reservoir for excess matrix material in fluid flow relationship with the article cavity. Gas pressure applied to the excess matrix material while in the fluid condition forces that material back into the article cavity to nominally eliminate voids, pores and other internal and surface discontinuities from the article.
