Aluminum matrix composite materials containing different volume fractions of SiC whisker (Al/SiC) and Saffil alumina short fiber (Al/ASl2O3) were fabricated by the direct squeeze infiltration method using different processing and aging conditions, and the mechanical properties of the resulting composites were investigated to find optimal fabrication conditions. Observations of the composites' microstructures showed that good bonding and uniform distribution of reinforcements were achieved. Results of hardness tests indicated that the optimum aging conditions for the composites containing 0.25 volume fraction of reinforcements were 6 hrs at 150 C and 4 hrs at 180 C. Compared to nonreinforced matrix, the mechanical properties of composites, such as hardness, Young's modulus and tensile strength, were improved by up to 80 percent. 39 refs.
