The objective of this program was to evaluate recently developed thermoplastic resins as matrix materials for graphite reinforced composites. Thermoplastic polymers (PKXA Polysulfone, Radel 5010 polyphenylsulfone, P-300, and KM-1 polyethersulfones, and CM-1 fluorocarbon based resin) having high temperature capability (+350 F) were evaluated as matrix materials for graphite reinforced composites. Resin characterization studies were performed. Prepreg processing and laminate molding parameters were optimized. Mechanical properties evaluations conducted consisted of flexure, tension, compression, shear, bearing, and impact strength. A study was conducted to determine resistance of the graphite fabric/thermoplastic composites to fluids likely to be encountered in aircraft flight and maintenance operations. Thin (0.01-in.) titanium sheet was bonded to the laminate faces and these 'clad' specimens immersed in fluids to determine if the clad specimens were more fluid resistant than unclad specimens. Postforming and thermal cycling studies were performed on the clad specimens. The feasibility of using two joining methods, spot fusion and use of a glue gun, for attaching graphite reinforced composite repairs patches to graphite reinforced composite structure was demonstrated.
