  • Perform for metal matrix composite material and cylinder block made of the same
    Patent number: 6383656
    Abstract: A preform for metal matrix composite material comprising: inorganic particles, small-diameter inorganic fibers, and large-diameter inorganic fibers. An average particle diameter of the inorganic particles is 1 to 50 &mgr;m. An average fiber diameter of the small-diameter inorganic fibers is 2 to 5 &mgr;m, and an average fiber length of the small-diameter inorganic fibers is 10 to 200 &mgr;m. An average fiber diameter of the large-diameter inorganic fibers is 4 to 20 &mgr;m, and an average fiber length of the large-diameter inorganic fibers is 10 to 200 &mgr;m. The small-diameter inorganic fibers catch and disperse the inorganic particles in a process of forming a formed body, and the large-diameter inorganic fibers create voids in cooperation with the small-diameter inorganic fibers in the process of forming the formed body.
