Abstract:Gr(C)/Mg composites were prepared by low-pressure infiltration. Results showed that the infiltration, interface reaction and tensile stress of composite materials were affected obviously by fabrication conditions. Through fiber SiO2coating and optimum infiltration processing, composite materials with high mechanical properties were produced. Its tensile strength was as high as 509 MPa and modulus of elasticity 142 GPa.
