Development of Processable High-Temperature Resins for Composite Materials (Preprint)

摘要

As part of a cooperative research and development agreement, the Navy, the Air Force, and Boeing are jointly working towards the development of novel processable polymer resins for structural applications requiring demanding thermal stability and hot-wet performance, targeting service temperatures in the range of 450 and 700 deg F. An overview of the program's approach and screening tools will be presented. Emphasis will be placed on the thermal and moisture absorption analysis techniques that are being implemented to guide resin formulation development ensuring facile liquid-molding processing, viz. resin-transfer molding (RTM) and resin film infusion (RFI). Some key findings regarding structure-property relationships are discussed.
