    摘要: By evacuating the resin feed tank to a pressure below atmospheric pressure, employing cyclic compaction, and controlling the net compaction pressure, we are better able to control a resin infusion process, particularly a vacuum assisted resin transfer molding process, and produce aerospace-grade fiber-reinforced resin composite having fiber volume fractions and tool-side surface finishes comparable to or exceeding those made using an autoclave.

    摘要: A composite item is fabricated in system that includes a layer of preform, supply of resin, mandrel, and bagging film. The layer of preform corresponds to the composite item. The supply of resin is sufficient to infuse the preform. The mandrel includes a preform receiving zone to receive the layer of preform and a resin receiving zone to receive the supply of resin. The resin receiving zone is adjacent to the preform receiving zone. The bagging film is operable to generate an envelope surrounding the preform receiving zone and the resin receiving zone.
