摘要

Toughened epoxy prepregs are utilized in advanced composite structures on military aircraft.rnThe conventional processing route employs autoclave curing under a pressure of 7 bars (100 psi)rnand long cycle times to achieve final properties. An out-of-autoclave advanced composite curingrntechnology has been employed that uses a heat transfer fluid (HTF) to apply heat and modestrnpressure to the uncured epoxy prepreg during processing. The HTF enables precise control of thernprocess temperature throughout the curing process. As this technology is based on rapid heatrntransfer and the ability to accurately control mold temperature, it offers potential savings onrnprocess time, energy, investment, and overall component manufacturing costs. Additionally, arndifferential vacuum technique has been applied to the laminates during the cure cycle that yieldsrnvoid-free laminates. This paper reviews the progression of the process development and thernresulting panel and component qualities. Data showing process parameters, laminate properties,rnand cured components are presented.
