Abstract
A slide member is made of an aluminum alloy and compositely reinforced at its sliding surface by a reinforcing material. The reinforcing material is a mixture of alumina short fibers consisting of not less than 80 wt. % alumina and the remainder silica and having 5-60 wt. % alpha alumina content, and non-spherical mullite particles consisting of 40-86 wt. % alumina and the remainder silica and having 3-60 microns mean diameter. The volumetric percentages of the alumina short fibers and the mullite particles are 2-12% and 5-25%, respectively, on the basis of the volume of the reinforced portion.
