An experimental investigation was made to determine the ultimate tensile strength and elastic modulus of HMF 330/34 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: (0/45/-45/90)s, (45/0/-45/90)s and (45/90/-45/0)s. 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 (0/45/-45/90)s orientation panel. For (45/0/-45/90)s and (45/90/-45/0)s 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.
