Abstract

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 G^Ic are described. Test results at room temperature and at cryogenic temperature are presented.
