Abstract

2dimension-continuous carbon fiber reinforced magnesium（2D-C

/Mg）composites were fabricated by liquid-solid extrusion directly combining with vacuum infiltration technique.The effects of different cooling rate on the carbon fiber

hardness and ultimate tensile strength of C

/Mg composites were analyzed.The experimental results reveal that a higher cooling rate can reduce the damage of carbon fiber

relief the interface reaction

and improve the ultimate tensile strength（UTS）and hardness of the composites prepared.The tensile strength of 2D-C

/Mg composites with T700 carbon fiber can reach 450 MPa.
