Abstract
The tensile and fatigue strengths of squeeze cast F332 aluminum alloy and its composites reinforced with 15 volume percent of discontinuous Fiberfrax® fiber after T5 heat treatment were determined at 400°C. Rotating beam fatigue testing was performed to determine the endurance strength of these composites for 50% probability of failure at 10 million cycles.
Substantial improvements in tensile and fatigue strengths were observed for the reinforced material compared to the matrix alloy. Long term 400°C thermal aging study indicates that there is no significant difference in fatigue strength between 100 hour and 1,000 hour aged samples.
