a strip specimen is cut from a unidirectional strong, brittle fiber composite material, and the surfaces of both ends of the specimen are grit-blasted. the specimen is then placed between metal load transfer members having grit-blasted surfaces. sufficient compressive stress is applied to the load transfer members to prevent slippage during testing at both elevated temperatures and room temperatures. the need for adhesives, load pads, and other secondary composite processing is eliminated. this gripping system was successful in tensil testing, creep-rupture testing, and fatigue testing uniaxial composite materials at 316 c
