The objective of this research was to investigate the effects of manufacturing variables (injection pressure, pre-heated temperature and vacuum assistance) on resin transfer molding (RTM). Specimens were made of 40 plies of TGFC-7628 cloth fiberglass mats or 12 plies of TGFW-600 woven roving fiberglass mats under different process conditions. The fiber volume contents of the specimens were 50.3% or 45% in the experiments. The flexural strengths of all the finished products tested by the method of three point bending were compared to each other to understand the influences of each process variable on the RTM products. Both the pre-heated temperatures and the injection pressure were found to affect the quality of the RTM product. 8 refs.
