Investigating cavity pressure behavior in high-pressure RTM process variants

摘要: The paper addresses new variants of the high pressure resin transfer molding (HP-RTM) process namely injection RTM (HP-IRTM) and compression (HP-CRTM) for manufacturing carbon fiber reinforced composites with volume content. Both these processes utilize high-pressure equipment precise dosing mixing highly reactive epoxy amine hardener relatively throughput rates. results a study which investigated cavity measurement both HP-RTM using specially designed highpressure mold. investigations indicate that built up is characteristic selected variant. Further relationship between applied press force in HP-CRTM was studied.
