Abstract:
A process for resin transfer molding (RTM) with staggered injection of a resin is provided that injects resin into a plurality of injection ports of a mold. The temperature and pressure applied to the mold are controlled during injection to limit promote rapid filling of the mold cavity. The injection ports are activated for injecting the resin in any order of individually, in groups, or pairings. Fibers are readily added to the mold separately or within the resin. Cycle times of from 1 to 5 minutes are provided for the process.
