製造されている。(Prior art) Currently, long fiber metal composite materials are usually formed in an array by the so-called drum winding method, in which metal foil with a thickness of 0.05 m to 11 mm and fiber filaments are wound around a drum at regular intervals and fixed with resin. The resulting fiber mats are cut to a predetermined size, stacked alternately, fitted into a mold, degreased in a vacuum, pre-solidified using a vacuum hot press, hot isostatic press (HIP) or a vacuum hot press, and then Manufactured using HTP hardening foil metallurgy.

に採算がとれるものではない。However, metals generally become less malleable as they are alloyed, and particularly highly alloyed Ti alloys and Ni alloys encounter the problem that they cannot be processed into thin foil shapes. Among these Ti alloys, Ti-6Ajl-4V alloy foil is produced as a two-phase alloyed (α phase β phase) alloy for use in experimental Ti alloy matrix composite materials, but it is expensive and is not suitable for industrial use. It is not something that can be economically profitable.

従って、前記箔冶金法は箔加工が困難な上記Ｔｉ合金、
Ｎｉ基合金には適していない。Therefore, the foil metallurgy method is suitable for the Ti alloy, which is difficult to process into foil.
Not suitable for Ni-based alloys.

As a result of working on the development of a Ni-based composite material and investigating a manufacturing method suitable for this material, we developed a Ti alloy.
Ｎｉ基合金の金属粉末のＩＩＩ用化に到達した。We have achieved the use of Ni-based alloy metal powder for III applications.

いる。Conventionally, methods for producing metal powder include mechanical methods and physical methods, which are often used in the production of various metal powders, but T
For Ti alloys, Ni5 alloys, etc., there are physical rotating electrode methods, inert gas atomization methods, etc. In the rotating electrode method, the powder material is used as an electrode, and arc or plasma is applied while rotating to rotate the molten part. This method uses centrifugal force to create powder, and is mainly used to produce Ti and Ti alloy powder.On the other hand, the inert gas atomization method atomizes molten metal using an inert gas to obtain powder. Many Ni-based alloys are produced using this method.

空ホットプレス。(Means for Solving the Problems) The feature of the method of the present invention that meets the above objectives is that the metal powder such as the Ti alloy or Ni-based alloy is molded to a desired thickness using a binder. This and a fiber mat in which fiber filaments are arranged at regular intervals and fixed with a binder are alternately laminated to form a preform.The preform is degreased in a vacuum, and then heated in a vacuum hot press.

複合材料を製造する粉末シート法による上記複合材料の
製造方法である。This is a method for producing the above-mentioned composite material using a powder sheet method in which a long fiber metal composite material is produced by HIP treatment or by first pre-solidifying with a vacuum hot press and then solidifying by HIP treatment.
ここで、前記金属粉末シートの成形は、例えばポリエス

が、合金粉末は成形後の粉末シーＨＥの７０％以下の粒
径のものを用いる。Here, the metal powder sheet is formed by forming a mixture of the required alloy powder and a binder on a release paper such as a polyester film using a knife, but the alloy powder is formed in the powder sheet HE after forming. Use particles with a particle size of 70% or less.
具体的にはシート成形に用いる粉末粒子径はシート厚さ
を制限するため、繊維体積率を考えると、０．５＋＋宵
以下が好適である。Specifically, since the powder particle diameter used for sheet molding limits the sheet thickness, in consideration of the fiber volume fraction, a diameter of 0.5++ or less is suitable.
又、下限については特に制限はないが、固化成形体の酸
素、窒素のトラップ量は粒子径が小さい程、高くなるた
めに１０μ以上とするのが良好である。The lower limit is not particularly limited, but the smaller the particle diameter, the higher the amount of oxygen and nitrogen trapped in the solidified compact, so it is preferable to set it to 10 μm or more.

おいては離型紙とナイフェツジの隙間に粉末が詰まり、
筋状の欠陥を往じるので好ましくない。Figure 1 shows the relationship between the particle size of the alloy powder and the powder sheet thickness (powder-binder mixture viscosity 70°000-130°
,000CP), and the maximum powder sheet thickness is 1
In the case of dragon, the maximum particle size of the powder is at most 0.6f1
If the particle size of the powder exceeds 70% of the thickness of the powder sheet after molding, the powder will clog the gap between the release paper and the knife.
This is not preferable because it causes streak defects.
又、成形時における上記バインダーと粉末との混合体の
粘度もシート製造に影響があり、通常、５０，０００Ｃ
Ｐ〜１５０，０００ＣＰの範囲が効果的である。In addition, the viscosity of the mixture of binder and powder during molding also affects sheet production, and is usually 50,000C.
A range of P to 150,000 CP is effective.
第２図はこの合金粉末の粒径と粘度との関係を示してお

ンダーが分離する傾向が強くなり、低粒子密度の縞模様
を生じる。FIG. 2 shows the relationship between the particle size and viscosity of this alloy powder. Below 50,000 CP, there is a strong tendency for the alloy powder and binder to separate during compaction, resulting in a striped pattern with low particle density.
一方、１５０，０００ＣＰ以上になると混合体の粘度が
高くなりずぎ、シー１−表面の肌荒れや混合体のとぎれ
たシートができる。On the other hand, if it exceeds 150,000 CP, the viscosity of the mixture becomes too high, resulting in a rough surface of the sheet 1 and a broken sheet of the mixture.
又、上記粉末シートはナイフェツジで成形後、乾燥する
が、この乾燥ば６０ ’Ｃ以下で行うのがよく、それ以
上ではシートと離型紙間に気泡を生じ表面が凹凸になる
恐れがあるので望ましくない。Further, the above powder sheet is dried after being molded with a knife, but this drying is preferably carried out at a temperature of 60'C or lower, as air bubbles may form between the sheet and the release paper and the surface may become uneven if the temperature is higher than that. do not have.

Fibers made of μ SiC filaments, SiC whiskers, SiC fibers produced by stereopolymerization of polycarbosilane, etc. are conceivable, but each should be used in consideration of their characteristics.
又、固定するバインダーとしては前述したアクリル樹脂
系バインダーの使用が実用的である。Further, as the binder for fixing, it is practical to use the above-mentioned acrylic resin binder.

Any method of IP processing can be implemented, but
The most effective method is to perform HIP treatment after preliminary assimilation using a final hot press.
