In order to obtain the high performance metal matrix composites with good reliability and high shape flexibility, we have designed the fabrication process of composites by low-pressure infiltration method. Followings are result of this study ; 1) Infiltration methods to porous preform with low-pressure were proposed. 2) Modeling and numerical simulation of infiltration and solidification processes was developed, and fabrication conditions of composites without casting defects were found. 3) Optimum process of composites was proposed by using the evaluation of mechanical and functional properties and the observation of microstructure of composites.
