Abstract : Graphite fibers were fabricated into NOL rings and biaxial-wound cylinders. Filament tensile strengths of NOL rings were determined at 75 deg, -320 deg, and -423 deg F (297, 77, and 20 K). Comparisons were made of ambient-temperature fiber tensile strengths as obtained from NOL rings, strand tests and biaxially wound cylinders. Fatigue characteristics of internally pressurized cylinders were determined at 75 deg and -320 deg F (297 and 77 K). Fatigue comparisons are made of graghite and glass-filament wound cylinders on the basis of specific strength. (MM)
