IMPROVED LAMINATE RESIN TRANSFER MOLDING OF FIBROUS PREFORMS USING PARTICLE FILLED RESIN SYSTEMS

摘要

A process for manufacturing a ceramic matrix composite component, said process comprising inserting at least one fibrous sheet (18) into a resin transfer molding system (10). The process includes wetting the at least one (dry or partially wetted) fibrous sheet (18) with a neat first pre-ceramic polymer resin (28). The process includes injecting a second pre-ceramic polymer resin including a filler material (34) into at least one fibrous sheet (18) and curing the pre-ceramic polymer resin (24).
