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 amorphous alumina-silica fiber material and mineral fiber material. The amorphous alumina-silica fiber material has as principal components 35% to 80% by weight of Al.sub.2 O.sub.3 and 65% to 20% by weight of SiO.sub.2, with a content of other substances of less than or equal to 10% by weight, with the percentage of non fibrous particles included therein being less than or equal to about 17% 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. 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 and bending strength are good.
