摘　　要：The preparation and properties of ceramic short fiber reinforced Al-Si alloy matrix composite and it's application on the piston for internal combustion engines are presented. Alumina or aluminosilicatefiibers reinforced Al-Si alloy matrix composite has more excellent synthetical properties at elevated temperature than the matrix alloys. A partially reinforced Al-Si alloy matrix composite piston produced by squeeze casting technique has a firm interface between reinforced and unreinforced areas, low reject rate and good technical tolerance. As a new kind of piston material, it has been used for mass production of about 400,000 pieces of automobile engines piston. China has become one of a few countries in which aluminum alloy matrix composite materials have been used in automobile industry and attained industrialization. 关键词：氧化铝纤维 Al-Si 合金合成活塞申请压榨扔
