In the current investigation, continuous SiC fibers/aluminum alloy composites using AA6061 alloy plates and preformed wires which consist of continuous SiC fibers and AA1050 aluminum have been prepared by a vacuum hot press method, and wear properties of these composites have been examined against S45C steel wheel under lubricant conditions. FRM prepared was the unidirection reinforced composites involving continuous SiC fiber of 4.3 vol%. Three kinds of composite surfaces classified by the reinforced direction of SiC fibers and two kinds of matrix surfaces distinguished by the cutting direction of the stacking alloy plates were used for a wear testing. The experimental results obtained are summarized as follows: (1) Wear loss of continuous SiC fibers/aluminum alloy composites is much smaller than that of the matrix alloy, and the SiC fiber in composites is found to improve wear resistance. (2) The reinforced direction of SiC fibers for wear resistance is more effective in the order of longitudinal>perpendicular>transverse. (3) The difference in the kinetic frictional coefficients is not recognized between the composite surface and the matrix one.
