摘要

The fatigue behavior and damage mechanisms of 2-D and 3-D carbon/epoxy composites with approximately the same 51/100 fiber volume fraction were investigated. A test program was con- ducted on fatigue residual strength and fatigue life under constant amplitude tensile fatigue loading. Equations of predicting the fatigue life for both 2-D and 3-D composites were provided.
