Abstract

The tensile-tensile fatigue behavior of a polymer-derived ceramic matrix composite was studied in air at room temperature, 982°C and 1204°C. The fatigue life was found to decrease with increasing stress according to the relationship σ_peak = σ_uts N_f^k, where σ_peak is the peak cyclic stress, σ_uts the monotonic ultimate tensile strength, k is a constant and N_f the number of cycles to failure. At elevated temperatures, the composite endured more than one million cycles (1 cycle = 2 reversals) for peak stresses below a well defined proportional limit stress observed during monotonic tensile testing. The role of the fiber coating and the fiber-matrix interface in the high temperature fatigue resistance of this material is discussed.
