Fatigue Response of Joint between Titanium and Titanium Matrix Composite

An integrally fabricated double scarf joint between a monolithic titanium alloy and the silicon carbide fiber reinforced titanium matrix composite was characterized under the fatigue loading condition. The mechanical response of the functionally graded material system was in-between those of the alloy and the composite under all loading conditions. There was a small improvement in fatigue life of the functionally graded material relative to that of the monolithic alloy.
