Abstract:
Tests were performed evaluating the effects of thermal spikes on the moisture absorption characteristics, the ultimate tensile strength, and the buckling modulus of Thornel 300/Fiberite 1034 composites. Measurements were made on unidirectional and angleply laminates, using different types of thermal spikes. A survey was also made of the existing data. This survey, together with the present data, indicate how thermal spikes affect the moisture absorption and the mechanical properties of different graphite-epoxy composites.
