HIGH TEMPERATURE AEROSPACE APPLICATIONS

摘要

Carbon fiber composite structures have been increasing in usage for aerospace applications due to their low density and high strength and stiffness properties. For certain applications such as commercial aircraft engines, high service temperature materials are increasingly being desired. Traditional epoxy resin systems which are suitable for the resin transfer molding process are deficient in either service temperature or impact resistance, limiting the expansion of their usage. A series of new resin transfer molding resins have been developed by 3M for carbon fiber composite structure which increase the service temperature of conventional epoxy resins while retaining the impact resistance. These systems are described in this paperwith supporting neat resin and composite laminate data.
