The objectives of the program are to study three basic hypotheses in fatigue of composite materials. Theese are 1 cyclic loading degradates the matrix properties and thus lower the compression strength more than tension-strength 2 the static strength and fatigue life have equal ranks and 3 the residual strength may increase. Both analytical and experimental approaches are used. The results are not yet conclusive. A sudden-death model is proposed to measure the degration of residual strength. Three regimes of residual strength are distinguished, these are the increase of strength, weak degradation, and strong degradation. Author
