Abstract
A method of forming a metal matrix composite component includes positioning a preform including an electrically non-conductive fibrous material in a shaping tool. The fibrous material is pre-coated. The method includes flowing a molten metal comprising zinc into the shaping tool so that at least a portion of the preform is enveloped by the molten metal to form the metal matrix composite component; and cooling the metal matrix composite component.
Claims10
A method of forming a metal matrix composite component, the method comprising:
- positioning a preform comprising an electrically non-conductive fibrous material in a shaping tool, wherein the fibrous material is pre-coated, wherein the preform comprises a metallic wire;
- flowing a molten metal comprising zinc into the shaping tool so that at least a portion of the preform is enveloped by the molten metal to form the metal matrix composite component;
- cooling the metal matrix composite component;
- and
- compressing the molten metal and the portion of the preform;
- wherein the shaping tool comprises a mold tool and a bag that at least partially encloses the mold tool, and compressing the molten metal and the portion of the preform includes:
- reducing a pressure within the bag with the molten metal and the portion of the preform on the mold tool.
