    摘要： Methods and apparatuses for making PMC's and composites include an infusing step wherein the resin reservoir and the preform are maintained under substantially the same vacuum pressure during the infusing step or the associated structure associated with the maintenance. Substantially the same vacuum pressure may be accomplished using a collapsible resin reservoir that is enclosed within or external to the vacuum bagging assembly of the fiber preform. This method results in a maximum achievable vacuum compaction pressure and simplified resin infusion process. This process may be used to manufacture prepregs and aerospace grade fiber reinforced resin composites, also disclosed herein, that have fiber volume, void content and laminate quality that meets or exceeds those made using an autoclave.
