Fabrication of Unidirectional Fiber Reinforced 6061 Aluminum Alloy Using High Pressure Squeeze Casting
Abstract
Aluminum Alloy castings have been successfully reinforced with unidirectional graphite fibers. The reinforced castings were fabricated using an innovative technique known as high pressure squeeze casting. Previously, squeeze casting has been recognized as a superior metal forming method. The materials fabricated in this study demonstrate the ability of squeeze casting to achieve good fiber distribution and infiltration without the need for pretreatment of the fibers. There was very little observed chemical reaction between the graphite fibers and the aluminum in the as-cast condition. The strength of the reinforced castings increased with increasing fiber volume fraction, although the strengths were generally less than those predicted by rule mixtures. The tensile strengths ranged from 120 MPa for fiber volume fractions of 5 percent to 52 percent, respectively. Aluminum castings, Aluminum alloys, Squeeze casting, Fiber-reinforced metal castings.
