METHOD FOR MANUFACTURING FIBER REINFORCED METAL COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing new fiber reinforced metal (FRM) by which a mold releasing plate having a product shape is unnecessary and the FRM having complicated shape can be taken out and it does not take much time for machining. SOLUTION: The method for manufacturing the new FRM includes: a process for placing a vessel 3 where a blank 1 for impregnating with the non-impregnating part of a preform coated with a graphite sheet is housed in a state it is embedded into a filling material 2 such as fused salt heated and fused, into a mold 7; a process for pouring the molten metal 5 into the mold 7 and for pressure-impregnating molten metal 5 from the impregnated part 4 in the blank 1 for impregnating; a process for taking out the formed body from the mold 7, cutting off the metal 5 covering the impregnated part 4 and exposing the filling material 2; and a process for taking out the blank 1 for impregnating from the formed body and for separating a graphite sheet, after dissolving the filling material 2 with water from the exposed portion.
