An experimental investigation has been conducted to study the behavior of a polyimide-resin/glass-fiber laminate over a range of temperatures from -320 deg F to 1050 deg F. The behavior was studied before and after various exposures to temperatures from 450 deg F to 800 deg F and pressures of 760, 35 and 10 to the -6th torr. Mechanical properties in flexure and shear were determined by 3-point bending tests on ...
