Technological Study on a Carbon Fiber Reinforced Aluminum Composite Prepared by a New Vacuum Squeeze Casting Process

Abstract:

A near net shaped carbon fiber reinforced Al composite was prepared by a new vacuum squeeze casting process. The technology of mixing fibers and fine particles, the choice of binders, as well as the effect of a carbon coating obtained using a sol gel method are studied in this paper. The experimental results show that the fibers in the composite have a moderate volume fraction and a good distribution. The tensile strength and elastic modulus of the composite reach 900MPa and 200GPa respectively.
