Alumina-aluminosilicate fibre hybrid reinforced aluminium-silicon alloy was fabricated by pressure infiltration route. Tensile test results at room temperature and at 300°C are reported. It is shown that the alumina-aluminosilicate fibre ratio does have a strong influence on the ultimate tensile strength (UTS) of these hybrid composites. At an alumina-aluminosilicate ratio of 3∶2, the optimum UTS of hybrid metal matrix composites (MMC) was obtained. The UTS of only alumina fibre reinforced MMC was improved with increasing fibre volume fraction at 300°C. No fibre put-out was observed on the fracture surface and longitudinal section.
