PCT No. PCT/EP91/00668 Sec. 371 Date Oct. 13, 1992 Sec. 102(e) Date Oct. 13, 1992 PCT Filed Apr. 9, 1992 PCT Pub. No. WO91/16159 PCT Pub. Date Oct. 31, 1991.Composite casting process for making castings, consisting in particular of light metal alloys reinforced by fiber or foamed material inserts, in particular motor parts such as pistons, cylinders, cylinder heads and motor blocks of internal combustion engines. In this process, firstly, a preform reinforced by the fiber or foamed material inserts is made by embedding and the penetration of a fiber bundle or a foamed material body in molten matrix metal or by a molten matrix metal and subsequently solidifying it. Then, the preform is immersed in a molten metal bath and subsequently inserted into a casting mould for integrally casting or casting around the final casting. In accordance with the invention, the preform is immersed into a molten metal bath which consists of the same or a similar metal or the same or similar metal alloy as the matrix metal of the preform or the metal used for integral casting or casting around the final casting and which is heated to a temperature which is higher than the melting point of the matrix material. |
