トリツクスとする繊維強化金属複合材料（図下
FRMと略記する）の製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention is a fiber-reinforced metal composite material (see the figure below) that uses inorganic fibers as a reinforcing material and a metal or alloy (hereinafter abbreviated as matrix metals) as a matrix.
(abbreviated as FRM)).

沈積法、押出、圧延などの塑性加工法などがある
が、加工上の容易さ、製造コストなどの点から液
相法が実用的である。 FRM has significant characteristics not seen in other materials in terms of specific strength, specific modulus of elasticity, and heat resistance, and its use is expanding in industrial fields such as space, aviation, and automobiles. FRM manufacturing methods include liquid phase methods such as molten metal impregnation, solid phase methods such as diffusion bonding, powder metallurgy (sintering, welding) methods, deposition methods such as thermal spraying, electrodeposition, and vapor deposition, extrusion, and rolling. There are plastic working methods such as , but the liquid phase method is practical from the viewpoint of ease of processing and manufacturing cost.
液相法によるFRM製造には下に示すような問
題点がある。即ち無機質繊維とマトリツクス金属

クス金属類との濡れ性を改善する方策が考えられ
ているが、繊維１本１本毎に均一にコーテイング
する事が困難で予期される効果が出にくい事と工
程の複雑さによつて、実用上問題がある。 FRM production using the liquid phase method has the following problems. That is, wetting between inorganic fibers and matrix metals is generally poor, and matrix metals do not impregnate the fiber gaps, often making it impossible to obtain a good FRM. Furthermore, the fiber bundles are often pushed to one side by the pressure of the molten metal and become unevenly distributed, making it impossible to install them at desired positions. In order to solve this problem, a method has been considered to improve the wettability with matrix metals by applying a coating to the surface of the inorganic fibers, but it is difficult to uniformly coat each fiber, which is expected. However, there are practical problems due to the difficulty in achieving the desired effect and the complexity of the process.
また、溶湯鍛造法やガス加圧含浸法を用いる事
によつて、濡れ性の悪いマトリツクス金属類と無
機質繊維を強制的に複合化する事は可能である
が、この方法の用いられるマトリツクス金属類は
比較的低融点を有しているものでなくてはならな
い。高融点を有するマトリツクス金属類にこの方
法を用いようとすると装置材質、規模等に特別の
配慮が必要であり、経済的でなくなる。 Furthermore, by using the molten metal forging method or the gas pressure impregnation method, it is possible to forcibly composite matrix metals with poor wettability and inorganic fibers; must have a relatively low melting point. If this method is used for matrix metals having a high melting point, special consideration must be given to the equipment material, scale, etc., making it uneconomical.
本発明者らは液相法によるFRM製造方法にで
特に高融点を有するマトリツクス金属類を用いて
も安価かつ容易に良好なFRMを製造する方法を
鋭意検討した結果、本発明に至つた。 The present inventors have intensively studied a method for producing a good FRM inexpensively and easily even when matrix metals having a particularly high melting point are used in the FRM production method using a liquid phase method, and as a result, the present invention has been achieved.
即ち、無機質繊維を強化材とし金属または合金

無機質繊維を収束した後、この集束繊維束を該マ
トリツクス金属類の溶融体と一体化し、冷却する
事により複合化する事を特徴とするFRMの製造
方法である。 That is, in an FRM in which inorganic fibers are used as reinforcement materials and metals or alloys are used as a matrix, the FRM has a melting point that is lower than the melting point of the matrix metals and 50°C or higher, and has a solubility in the matrix metals that is higher than that of the matrix metals. At a temperature 10℃ higher than the melting point
After converging the inorganic fibers in advance with one or more metals (hereinafter abbreviated as convergent metal elements) having a volume of 10% or more, the convergent fiber bundle is integrated with the melt of the matrix metal. This is a manufacturing method for FRM, which is characterized by compounding by oxidizing and cooling.
以下に本発明を詳細に説明する。 The present invention will be explained in detail below.
本発明に用いられる無機質繊維とは、炭素繊
維、シリカ繊維、シリコンカーバイド繊維、ボロ
ン繊維及びアルミナ質繊維などである。使用目
的、強化目的に従つてこれら無機質繊維の適当な
のを選択する事が好ましい。 Inorganic fibers used in the present invention include carbon fibers, silica fibers, silicon carbide fibers, boron fibers, and alumina fibers. It is preferable to select an appropriate inorganic fiber according to the purpose of use and reinforcement.
また、使用目的に基づいてロービング状、繊布
状、不織布状またはチヨツプドストランド状など
如何なる形態にても本発明に用いる事ができる。 Moreover, it can be used in the present invention in any form such as roving, fabric, nonwoven fabric, or chopped strand depending on the purpose of use.
無機質繊維の体積含有率（Vf1）はFRMに対し
て５％以75％以下が望ましい。５％以下では繊維
による強化効果が発揮しがたい。75％以上では複
合化が困難であるばかりか、繊維間の接触確率が
高まり、逆に強度が低下するほどの悪影響が見ら
れる。 The volume content (V f1 ) of the inorganic fibers is preferably 5% to 75% of the FRM. If it is less than 5%, it is difficult to achieve the reinforcing effect of the fibers. If it exceeds 75%, it is not only difficult to form a composite, but also the probability of contact between fibers increases, which has such an adverse effect that the strength decreases.
マトリツクス金属類として用いられるものはマ
グネシウム、アルミニウム、銅、ニツケル、チタ

好適なマトリツクス金属類が選択される。 The matrix metals used include magnesium, aluminum, copper, nickel, titanium, iron, lead, tin, and zinc. When you want light weight and high strength, use magnesium, aluminum, etc.
When heat resistance and high strength are desired, copper, nickel, titanium, iron, etc. are preferable, but suitable matrix metals are selected depending on the purpose and application.

元素類で集束された無機質繊維束（集束繊維束）
とマトリツクス金属類を複合化する前に集束金属
元素類が液化してしまい、集束繊維束形状が崩れ
るなどの不都合が生ずる。 The focused metal elements must have a melting point lower than the melting point of the matrix metals and at least 50°C, and have a solubility in the matrix metals of 10% by volume or more at a temperature 10°C higher than the melting point of the matrix metals. No. When the melting point is lower than 50℃, it is an inorganic fiber bundle that is bundled with a metal element (bundled fiber bundle).
The focused metal elements are liquefied before they are combined with the matrix metals, causing problems such as the shape of the focused fiber bundle being distorted.

属類の融点より高い場合は集束繊維束とマトリツ

解し切らずに無機質繊維の周囲に集束金属元素類
が残在したまま複合化される事になり、マトリツ
クス金属の効果が発揮されなくなる。 In addition, if the melting point of the focusing metal elements is higher than the melting point of the matrix metals, when the focusing fiber bundle and the matrix metals are combined, the focusing metal elements are in a solid state, so diffusion into the matrix is slow, and the focusing metal elements are in a solid state. Since the fiber bundles remain in their original state in the matrix, the original purpose of compositing is often not achieved. In addition, if the solubility of the focused metal elements in the matrix metals is less than 10% by volume at a temperature 10°C higher than the melting point of the matrix metals, the focused metal elements will not completely dissolve in the matrix metals and become inorganic. The focused metal elements will remain around the fibers and will be composited, and the effect of the matrix metal will no longer be exhibited.
この様な集束金属元素類の好適なものは、マト

から選択される。 Suitable focusing metal elements are limited by the type of matrix metal, but include lithium, sodium, potassium, magnesium,
Examples include calcium, strontium, barium, copper, zinc, cadmium, aluminum, indium, germanium, tin, lead, antimony, and bismuth. Of course, once the matrix metals are determined, metal elements that meet the above conditions are selected from among these metal elements.
集束繊維束における繊維の体積含有率（Vf2）

以上である。Vf2が30％以下の場合、マトリツク

類の特性を著しく損なう。 Volume content of fibers in focused fiber bundle (V f2 )
can be in any range, but preferably 30℃
That's all. When V f2 is 30% or less, the concentration of the focused metal elements in the matrix metal increases after being composited with the matrix metal, significantly impairing the properties of the matrix metal.

を用いてこれらの集束繊維束を製造する事が可能
である。 Various methods can be used to bundle the inorganic fibers with a binding metal element, and examples of suitable methods include liquid metal impregnation and molten metal forging. Since the melting point of the focusing metal elements is relatively low, it is possible to produce these focused fiber bundles using simple equipment.

法の一例として重力鋳造法、低圧鋳造法、高圧鋳
造法、溶湯鋳造法などがあげられる。 Generally used methods are used to composite the focused fiber bundle made in this way with matrix metals.
Although FRM manufacturing technology can be applied, a method that exhibits the effects of the present invention even more clearly is a manufacturing method using a liquid phase. This is because the focused metal elements tend to diffuse and dissolve into the matrix metal. Examples of this method include gravity casting, low pressure casting, high pressure casting, and molten metal casting.
