Abstract
An aluminum alloy slide support member which is disclosed herein as a cylinder block of an internal combustion engine includes a slide portion, such as the cylinder for slideably supporting the piston, made of a fiber-reinforced aluminum alloy containing at least an alumina fiber as a reinforcing material, wherein the alpha rate of the alumina fiber is set in a range of 10.0 to 50.0% and the volume content of the alumina fiber is set in a range of 8.0 to 20.0%. Another embodiment employs carbon fibers in addition to the alumina fibers. Further, the walls of the cylinder barrel are of a varying thickness to equalize the cooling and cause uniform thermal expansion of the cylinder barrel.
