ABSTRACT:
This composite material includes reinforcing hybrid fiber mixture material in a matrix of metal which is aluminum, magnesium, copper, zinc, lead, tin, or an alloy having these as principal components. The hybrid fiber mixture is a mixture of alumina fiber material and mineral fiber material. The alumina fiber material has principal components of at least about 80% by weight of Al.sub.2 O.sub.3 and remainder substantially SiO.sub.2. And the mineral fiber material has as principal components SiO.sub.2, CaO, and Al.sub.2 O.sub.3, the content of MgO being less than or equal to 10% by weight, the content of Fe.sub.2 O.sub.3 being less than or equal to 5% by weight, and the content of other inorganic substances being less than or equal to 10% by weight, with the percentage of non fibrous particles being less than or equal to 20% by weight, and with the percentage of non fibrous particles with diameters greater than 150 microns being less than or equal to 7% by weight. The volume proportion of the reinforcing hybrid fiber material is at least 1%. The qualities of this composite material with regard to wear, wear on a mating member, and bending strength are good.
