A new model was developed to predict the creep-rupture life of continuously reinforced titanium matrix composite subjected to sustained transverse loading. The proposed model assumes that the maximum net-section stress in the matrix ligament dictates the rupture life of the transverse composite. A good correlation was observed between the predictions of the net-section model and the measured creep-rupture life. The failure depends on the ratio of fiber diameter to ply thickness and the failure is independent of fiber spacing parallel to the loading direction. The proposed model predicted a reasonable lower bound solution and should be an useful conservative design tool. The Wright-Crossman (W-C) model was found to be non-conservative.
