摘要：
The influence of vacuum level, fluid type and preform type on the mold filling phase of the resin transfer molding process was experimentally investigated for a flat mold with unidirectional flow. The wetting out process of different preforms was experimentally investigated. The relative effect of macro-flow and micro-flow was examined for the different liquid-preform systems. Resin-mat system clearly shows the effect of macro-flow and micro-flow competition on the preform wet out, depending on the vacuum level. The equivalence between pressure gradient due to vacuum and pressure gradient due to imposed injection pressure is examined.
