Abstract:

An experimental investigation was made to determine the ultimate tensile strength and elastic modulus of HMF 33034 woven style graphite epoxy exposed to elevated temperatures 16 C, 50 C, 80 C, 110 C, 140 C, and 170 C. Specimen were of three different layups 045-4590s, 450-4590s and 4590-450s. An instron universal testing machine with 20,000 lb maximum load capacity was used to apply the uniaxial tensile loading. A Marshall clamshell furnace was used for maintaining the elevated temperatures. Results of the investigation indicate that ultimate tensile strength decreases with temperature increase in the 045-4590s orientation panel. For 450-4590s and 4590-450s orientation panels, ultimate tensile strength increases with temperature up to 140 C 284 F, and decreases above 140 C 284 F. In all cases, the elastic modulus decreases as temperature increases.
