Abstract:
A method of forming fiber reinforced polymer matrix composite structures having a low volume fraction of fiber reinforcement and carefully controlled thicknesses is provided. The method enables the production of composite structures having a fiber volume fraction of less than about 0. 5 through the use of vacuum bag molding, thereby eliminating the need for expensive closed molds, The method also eliminates the occurrence of âracetrackingâ of uncured resin during the resin infusion process.
