Application of Ceramic Short Fiber Reinforced Al Alloy Matrix Composite on Piston for Internal Combustion Engines
In this paper, the preparation and properties of ceramic short fiber reinforced Al-Si alloy matrix composite and its application on the piston for internal combustion engines are reported. Alumina or aluminosilicate fibers reinforced AlSi 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 materials, it has been produced by batch production about 400000 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 attAln industrialization.
