Abstract
A composite material, including reinforcing fiber material with principal components SiO.sub.2 and/or CaO and/or Al.sub.2 O.sub.3, and with a Mg content by weight of between about 0% and about 10%, an Fe.sub.2 O.sub.3 content by weight of between about 0% and about 5%, and a content by weight of other inorganic substances of between about 0% and about 10%, and consisting essentially of mineral fibers and non fibrous particles to a total percentage of not more than about 20% by weight, the weight percentage of the part of the non fibrous particles which have a diameter of greater than or equal to about 150 microns being between about 0% and about 7%. Also, the composite material includes a matrix metal selected from the group consisting of aluminum, magnesium, copper, zinc, lead, tin, and alloys having these as principal components, the volume proportion of the mineral fibers being in the range of from about 4% to about 25%. This composite material is economical to manufacture and has very good wear characteristics, machinability, and bending strength.
