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 into a resin transfer molding system. The process includes wetting the at least one (dry or partially wetted) fibrous sheet with a neat first pre-ceramic polymer resin. The process includes injecting a second pre-ceramic polymer resin including a filler material into at least one fibrous sheet and curing the pre-ceramic polymer resin.
