An efficient method for producing and testing organic-matrix composite specimens for research purposes is described. The production method is adaptable to in-house manufacturing and provides complete control over a large variety of material and processing variables. The rod-shape, uniaxially reinforced or neat-resin specimens may be cut to length and tested without further machining. Conventional short-beam shear, flexural strength, and compression test methods may be used. Development of test methods for performing torsional shear tests and for determining the fracture energy GIc are described. Test results at room temperature and at cryogenic temperature are presented.
