A program was conducted for investigation of materials to provide improved thermal resistance in an aviation fuel environment. Toward providing polymerics structures with improved thermal resistance, four classes of materials were investigated. These were coated foams, uncoated foams, filled thermoplastics, and unfilled thermoplastics. Specific materials were selected and evaluated for their retention of mechanical performance as a function of time following exposure to JP-5 fuel at elevated temperatures. The most promising materials obtained in the program consisted of a polyester fiber mat and a low-density open- celled polyimide foam. Of the thermoplastics investigated, the nylon, polyimide, and polymer 360 all exhibited substantial retention of mechanical properties in the hyperthermal fuel environment. Of importance was the inclusion of glass fillers, which provided geometrical integrity to the thermoplastic while at the elevated temperatures.
