Abstract: The tensile and impact fractography of carbon fiber reinforced zinc composite prepared by位eans of vacumn liquid-infiltration were investigated respectively with the aid of scanning electron microscopy.The fracture process of the composite was also studied by kinetic longitudinal, off-axis uniaxial and transverse tests.The results show that its normal fracture has a lot of filaments pulled-out and the matrices cleavaged.Its fracture process is that higher stresses at the tip of cracks initiated in the matrices or at the w eaker interface result in debonding of carbon fiber so that the filaments are broken and pulled out,sim ultaneousely othercracks in the matrices propagate and connect along their cleavage planes,leading to the failure of the composite,The influence factors upon the fracture of the composite,such as interfacial bonding strength,fiber orientation and distribution,have also been discussed in this paper.
