造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION C. Industrial Field of Application The present invention relates to a method for producing a 1+1 composite material of a fine hollow sphere metal bar, in which an aggregate of inorganic fine hollow spheres is impregnated with molten metal under pressure and solidified.

、巾広い分野において実用化が検討されている。Micro hollow spherical metal composite materials such as alumina, silica, graphite, and shirasu have excellent properties such as lightness, heat resistance, sound insulation, and rigidity, so they are used as building materials such as door materials, ceiling panels, floor materials, and aircraft. Practical applications are being considered in a wide range of fields, including parts for transportation systems such as automobiles and ships.
微小中空球体金属複合材料の製造方法は、加圧鋳造法、
減圧鋳造法、溶湯および粉末混合法等があるが、生産性
および経済性の点から加圧鋳造法が最も一般的である。The manufacturing method of micro hollow sphere metal composite material is pressure casting method,
There are vacuum casting methods, molten metal and powder mixing methods, etc., but the pressure casting method is the most common in terms of productivity and economy.

造法である。In the pressure casting method, microscopic hollow spheres of alumina, silica, graphite, shirasu, etc. are filled into a mold, heated to a certain temperature, and then
This is a manufacturing method in which a molten metal serving as a base material is poured into this mold, and pressure is applied to impregnate and solidify the molten metal into an aggregate of microscopic hollow spheres.

が失われる。However, in the above manufacturing method, there was a problem that the micro hollow spheres were destroyed during the process of impregnating the aggregate of the micro hollow spheres with the base metal molten metal. That is, when the impregnation pressure of the molten metal is high, the micro hollow spheres are destroyed by the influence of the hydrostatic pressure of the molten metal, and the molten metal permeates inside the micro hollow spheres, resulting in a loss of lightness.
また微小中空球体の静水圧破壊をおさえるため含浸圧力
を低くした場合は、巣欠陥等の内部欠陥を起こし、健全

。Furthermore, when the impregnation pressure is lowered to suppress hydrostatic fracture of the micro hollow spheres, internal defects such as nest defects occur, making it impossible to obtain a healthy micro hollow sphere metal composite material.

合材料を得る製造方法を開発したものである。As a result of various studies on the above-mentioned problems, the present invention has found that the destruction of micro hollow spheres in pressure casting greatly affects the pressing force of the molten metal and the shell thickness of the micro hollow spheres,
By adjusting these, we have developed a manufacturing method to obtain a healthy micro hollow sphere metal composite material.

法である。[Means and effects for solving the problem] The present invention provides a method for manufacturing a micro hollow sphere metal composite material in which an aggregate of inorganic micro hollow spheres is impregnated with molten metal under pressure and solidified. is 10 to 30-, gold i
This is a method for producing a micro hollow sphere metal composite material, characterized in that the pressure of the molten metal is 0.1 to 0.5 ton/cd.

得られるものである。That is, in the present invention, the shell thickness of the IIl-free micro hollow spheres is reduced to 1.
By filling a mold with 0 to 30 micron particles, pouring molten metal to serve as the base material, and impregnating and solidifying it under pressure of O,I ~0.5 ton/cd, there is no destruction of the micro hollow spheres. , and a healthy micro hollow sphere metal composite material free of nest defects can be obtained.

範囲では殻厚に関係なく微小中空球体が破壊するためで
ある。However, the reason why the shell thickness of the micro hollow spheres is set at 10 to 30 is that if the shell thickness is less than 10 -, if the pressure required to impregnate and solidify the molten metal is applied to the aggregate of the micro hollow spheres, it will break due to the hydrostatic pressure of the molten metal. This is because if the thickness exceeds 30μ, breakage will be reduced, but the weight reduction effect will be reduced. In addition, the pressure is set at 0.1 to 0.5 ton/c- because if the pressure is less than this, the molten metal will not completely impregnate the aggregate of micro hollow spheres, and if the pressure is higher than this, the hollow spheres will be usable. This is because the micro hollow spheres are destroyed in the range of , regardless of the shell thickness.

A micro hollow sphere metal composite material which is completely impregnated and has no nest defects etc. can be obtained.
