SiC fiber reinforced Ti-6Al-4V composites (TMCs) was prepared by the foil-fiber-foil method. The fatigue crack growth rate of the TMCs was investigated under the condition of f=10 Hz, R=0.1 and σmax =300 MPa, and the fracture surface of TMCs was observed by scanning electron microscopy (SEM). Results show that the crack growth rate at the stage Ⅱ of crack propagation is well consistent with Gaussian function. SEM observation indicates that distinct fatigue striations exist in the stable propagation area of the fatigue crack of the Ti-6Al-4V matrix. The failure modes of TMCs include fiber breakage, matrix cracking, fiber/matrix interfacial debonding, et al under the loading condition
