The Al-SiC_p composite was fabricated by the liquid mixing and squeeze casting method. The effects of squeezing pressure in the fabrication of the Al-SiC_p composite were studied by analysing microstructure and mechanical properties. The results could be summarized as follows; 1) The tensile strength and hardness of Al-SiC_p composite were increased as the squeezing pressure was increased. However, the elongation and amount of wear were decreased as the squeezing pressure was increased. 2) When the high squeezing pressure at the high molten temperature was applied in fabrication, the mechanical properties of Al-SiC_p composite were declined, which resulted from the deterioration of SiC_p particles in the matrix alloy. 3) The wear mechanism at the matrix alloy only was changed from adhesive wear to oxidation wear and from oxidation wear to fusion wear. However, the Al-SiC_p composite represented sliding wear mechanism resulting from the sliding action of SiC_p particles in the matrix alloy.
