Abstract

PURPOSE:To produce a composite material having good adhesion between a reinforcing material and molten matrix metal, by introducing the reinforcing material in the mold cavity having a material which evolves heat by a prescribed reaction stuck thereto, heating said material then introducing the molten metal into a casting mold. CONSTITUTION:A thermit material 4 is stuck to the wall surface 3 in the forming chamber 2 of a casting mold 1. For example, alumina fibers 5 are heated together with a stainless steel cylindrical case 6 contg. said fibers to a required temp. and are then disposed in the chamber 2. Then, the material 4 is ignited to induce thermit reaction. The melt 8 of an Al alloy is charged into a pressurizing chamber 7 communicating with the chamber 2, and is pressurized by a plunger 9 and after the pressurized state is maintained, the melt 8 is thoroughly solidified. Thereafter, the solidified body is removed by a knockout pin 10, and the case 6 and the Al alloy solidifying and sticking around the same are machined off, and the composite material of the alumina fibers and the Al alloy is taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION Komei Komei is concerned with 111 methods for making compound monthly interest rates, and also provides credit unions with 'A1. i j J method (, 2).

One of the methods for manufacturing compound monthly interest is to fill a mold with reinforcing material, introduce molten 71-rix metal into the mold, and insert a blank Ic J, which is engaged with the mold, into the mold.
A so-called high-pressure casting method is known in which a single helix metal is solidified while being heated to 11 degrees Celsius in a mold.

In this high-pressure casting method, as proposed in Japanese Patent Application No. 1983-'I070/I ('1) filed by the same applicant as the present applicant, (During 1 etc., the molten 71~lix metal should not penetrate into the ()T1°), thereby directing the reinforcing material and the 71~lix metal into a tight blind hole. Preheat to a temperature above the melting point of the trix metal and introduce the molten 7 trix metal I
