Abstract
A preform for the composite material and an aluminum composite material which can form a composite material has excellent abrasion resistant property and high strength and a manufacturing method of the same are disclosed. A pre-mixture 9 comprising aluminum borate whisker 3 and potassium titanate whisker 4 in the range of 5% to 20% by volume was sintered at certain temperature. The titanium oxide 11 produced by the whisker reaction was bound to the surface of aluminum borate whisker 3, and the preform having high strength was obtained accordingly. Aluminum composite material 10 having excellent abrasion resistant property and high strength was obtained by impregnating aluminum alloy 6 to preform 1 for composite material.
