摘要：
A cylinder liner or a cylinder block's bore portion formed of a composite alloy material reinforced with fibers and dispersed with ceramic particles. In the cylinder liner or the bore portion of the cylinder block, ceramic particles and alumina short fibers are uniformly dispersed in a light metal matrix. For producing the cylinder liner and the cylinder block, a preform having a shape identical with the cylinder liner or the bore portion is produced by mixing together the ceramic particles and the alumina short fibers. Molten light metal is infiltrated into voids of the preform during casting.
