CONTROLLED ATMOSPHERIC PRESSURE RESIN INFUSION PROCESS

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 surfa ce finishes comparable to or exceeding those made using an autoclave.
