Method for resin transfer molding

摘要

A resin reservoir particularly adapted for use with a resin transfer molding process. This reservoir comprises a pressure yielding porous sponge containing about two to about ten times the sponge's weight in resin. The reservoir is used in a resin transfer molding process. The process comprises applying pressure to a pressure yielding porous sponge containing resin to transfer the resin to a porous article precursor. The resin reservoir facilitates resin transfer molding by providing a resin reservoir that can ensure the desired impregnation of a porous preform such as a dry fiber composite precursor.
