Foreign Object Damage and Fatigue Interaction in Unidirectional Boron/Aluminum-6061


An experimental program was conducted to study the effects of foreign object damage (FOD) on the bending fatigue characteristics of a composite material, unidirectional boron/aluminum-6061. Fatigue curves were generated for a control group and each of four levels of FOD. The composite was further, characterized by static tensile and nondestructive tests. All tests were carried out at room temperature. A similar damage and fatigue experiment was done for a titanium alloy, Ti-6A1-4V, to provide baseline data with which to compare the composite. It was concluded that the composite suffers a greater percentage reduction in fatigue strength than does Ti-6A1-4V for a given impact energy.
