Abstract : A design allowables test program was conducted on Celion 3000/PMR-l5 and Celion 6000/PMR-15 graphite/polyimide composite to establish material performance over a 116K (-250 deg F) to 589K (600 deg F) temperature range. Effects of aging, thermal cycling and moisture were also evaluated. Tension, compression and properties were determined for uniaxial, pseudoisotropic and +/- 45 laminates. Test results show sufficient strength and stiffness to substantiate graphite/polyimide composites as an acceptable structural material for high temperature structural applications. (MM)
