  • Liquid pressure forming
    Patent number: 8807199
    Abstract: A method of pressure forming a metal matrix composite (MMC), comprises: placing a fiber preform (not shown) into a die cavity (14) defined by a split die (12); introducing molten metal into the die cavity (14) through a sprue (16) to envelope the fiber preform; sealing the sprue (16); applying pressure direct to molten metal in the die cavity (14) with a mechanical compaction piston (18) to encourage infiltration of the fiber preform during solidification.
