METHOD FOR PRODUCING A SUBSTANTIALLY VOIDLESS FILAMENT REINFORCED RESIN MATRIX COMPOSITE

摘要

A method of producing a substantially voidless filament reinforced resin matrix composite comprising placing a filament reinforced uncured resin matrix composite in a mold cavity to occupy a portion of the cavity, the resin matrix being at least partially desolvated and containing voids, filling the remaining portion of the cavity with dry uncured resin powder of the same resin as the matrix resin and compression molding whereby the resin powder melts and acts to transfer pressure isostatically to the composite and to infiltrate the resin matrix and fill the voids.
