【発明の詳細な説明】
本発明は、炭素繊維強化金属の製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing carbon fiber reinforced metal.
炭素繊維強化金属は、金属単体にくらべて一般
に軽量であり、また高弾性、高強度であるととも
に耐摩耗性、耐熱性などの点においても優れてい
るといわれている。しかしながら、炭素繊維は金
属と濡れにくいという性質を有するため、金属と
炭素繊維とを単に複合することによつては、上記
のような優れた特性を有する炭素繊維強化金属は
なかなか得られない。 Carbon fiber-reinforced metals are generally lighter than metals alone, and are said to have high elasticity and strength, as well as excellent wear resistance and heat resistance. However, since carbon fibers have the property of being difficult to wet with metals, it is difficult to obtain carbon fiber-reinforced metals with the above-mentioned excellent properties by simply combining metals and carbon fibers.
炭素繊維の濡れ性を改善し、上記のような優れ
た特性を有する炭素繊維強化金属を得るために、
マトリツクスとなる銅やニツケルなどの金属の溶
湯中に、その溶湯に触れても溶融しないほど十分
に高い融点を有する金属、たとえば白金、ロジウ
ム、ルテニウム、パラジウムなどの金属を被覆し
た炭素繊維を浸漬し、次いでこの溶湯中から炭素
繊維を引上げてその所望量を集め、加圧加熱して
一体化する方法が知られている。 In order to improve the wettability of carbon fibers and obtain carbon fiber-reinforced metals with the above-mentioned excellent properties,
Carbon fibers coated with metals such as platinum, rhodium, ruthenium, palladium, etc., which have a sufficiently high melting point so that they do not melt even when they come into contact with the molten metal, are immersed in a molten metal such as copper or nickel that forms the matrix. Next, a method is known in which carbon fibers are pulled up from this molten metal, a desired amount of carbon fibers are collected, and the fibers are integrated by pressurizing and heating.
しかしながら、このような方法によつて得られ
た炭素繊維強化金属は、炭素繊維の被覆金属がマ
トリツクスとなる銅やニツケルなどの金属中に溶
込まず、炭素繊維の周囲を囲むように残存してい
るので、その金属と被覆金属との接触面で電食が
起つて上記諸特性が低下したり、たとえば摺動材
として使用したような場合には、摺動面の摩耗に
伴つて上記被覆金属が摺動面の表面に露出し、耐
摩耗性が低下したり、相手材を傷損したりすると
いう欠点があつた。 However, in the carbon fiber-reinforced metal obtained by such a method, the coating metal of the carbon fiber does not dissolve into the matrix metal such as copper or nickel, and remains surrounding the carbon fiber. As a result, electrolytic corrosion may occur on the contact surface between the metal and the coating metal, resulting in the deterioration of the above properties.For example, when used as a sliding material, the coating metal may deteriorate as the sliding surface wears. This has the drawback that the material is exposed on the surface of the sliding surface, resulting in decreased wear resistance and damage to the mating material.
一方、上記方法において、アルミニウム溶湯中
にニツケル被覆炭素繊維を浸漬することも行なわ
れている。この場合には、ニツケルがアルミニウ
ム中に拡散し、炭素繊維の表面から離散する。し
かしながら、この離散したニツケルはアルミニウ
ムと反応して非常に脆い金属間化合物を形成する
ので、このような方法によつて得られた炭素繊維
強化金属はマトリツクスの機械的強度が低く、到
底実用に供し得ないものであつた。 On the other hand, in the above method, nickel-coated carbon fibers are also immersed in molten aluminum. In this case, the nickel diffuses into the aluminum and becomes discrete from the surface of the carbon fiber. However, since this discrete nickel reacts with aluminum to form a very brittle intermetallic compound, the mechanical strength of the matrix of the carbon fiber reinforced metal obtained by this method is low and it cannot be put to practical use. It was something I couldn't get.
本発明の目的は、従来技術の上記欠点を解消
し、機械的強度が高く、かつ耐摩耗性などの諸特
性に優れた炭素繊維強化金属の製造方法を提供す
るにある。 An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a method for manufacturing carbon fiber reinforced metal that has high mechanical strength and excellent various properties such as wear resistance.
上記目的を達成するために、本発明において
は、ニツケルを被覆した炭素繊維を、銅もしくは
銅を主成分とする金属の溶湯に浸漬して前記ニツ
ケルと金属とを相互に、かつ均一に拡散せしめて
合金化し、次いで前記溶湯から前記炭素繊維を引
上げてその所望量を集め、加圧加熱して一体に成
形することが特徴とする炭素繊維強化金属の製造
方法が提供される。 In order to achieve the above object, in the present invention, carbon fiber coated with nickel is immersed in a molten metal of copper or a metal whose main component is copper, so that the nickel and the metal are mutually and uniformly diffused. There is provided a method for manufacturing a carbon fiber reinforced metal, characterized in that the carbon fibers are alloyed using the molten metal, and then the carbon fibers are pulled up from the molten metal, a desired amount thereof is collected, and the carbon fibers are pressurized and heated to be integrally formed.
本発明を詳細に説明するに、炭素繊維は直径３
〜20（μ）程度のもので、その形態は長さ数十ミ
リメートル以下の短繊維や、長繊維、あるいは織
物、編物、マツト、不織布などの布帛状をしてい

ス中にそのマトリツクスに対し10〜70（体積
％）、好ましくは30〜60（体積％）含有せしめら
れる。 To explain the present invention in detail, the carbon fiber has a diameter of 3
~20 (μ), and its form is short fibers with a length of several tens of millimeters or less, long fibers, or fabrics such as woven, knitted, matte, and nonwoven fabrics. Such carbon fibers are contained in the matrix in an amount of 10 to 70 (vol%), preferably 30 to 60 (vol%).
上記のような炭素繊維へのニツケルの被覆は電
気メツキ、無電解メツキ、蒸着、溶射などの方法
によることができる。なかでも、炭素繊維に損傷
を与えることが少なく、かつ被覆厚を均一にする
ことが容易な電気メツキによる方法が特に好まし
く用いられる。 Nickel can be coated on the carbon fibers as described above by methods such as electroplating, electroless plating, vapor deposition, and thermal spraying. Among these, a method using electroplating is particularly preferably used because it causes little damage to the carbon fibers and it is easy to make the coating thickness uniform.
炭素繊維に対するニツケルの被覆厚は、製造し
ようとする炭素繊維強化金属のマトリツクス組成
を考慮して決定する。たとえば、マトリツクス中
に占めるニツケルの量を比較的少なくしたい場合
には0.1〜0.5（μ）程度、上記ニツケル量を比較
的多くしたい場合には0.5〜３（μ）程度とす
る。 The thickness of the nickel coating on the carbon fibers is determined in consideration of the matrix composition of the carbon fiber reinforced metal to be manufactured. For example, if the amount of nickel occupied in the matrix is desired to be relatively small, it is about 0.1 to 0.5 (μ), and when it is desired to make the amount of nickel relatively large, it is about 0.5 to 3 (μ).
炭素繊維強化金属のマトリツクスを形成する金
属としては銅、または銅を主成分とし、その銅中
に少量の錫、亜鉛などを添加したものが用いられ
る。これら錫や亜鉛の添加は、炭素繊維強化金属
の機械的強度や耐摩耗性などの特性を一層向上さ
せるうえで効果がある。 The metal used to form the carbon fiber reinforced metal matrix is copper, or copper as a main component, with a small amount of tin, zinc, etc. added to the copper. The addition of tin and zinc is effective in further improving the mechanical strength, wear resistance, and other properties of the carbon fiber reinforced metal.
さて、上記のようなニツケル被覆炭素繊維と金
属とを用いて炭素繊維強化金属を製造するには、
まず、ニツケルを被覆した炭素繊維を銅または銅

とする金属は、その酸化を防止するため不活性ガ
ス雰囲気中におくのが好ましい。 Now, in order to manufacture carbon fiber-reinforced metal using the above-mentioned nickel-coated carbon fiber and metal,
First, carbon fiber coated with nickel is immersed in a molten metal of copper or a metal whose main component is copper. While this immersion is being carried out, nickel is diffused into the copper or copper-based metal, and copper or copper-based metal is diffused into the nickel.
Alloyed. In this case, copper or a metal containing copper as a main component is preferably placed in an inert gas atmosphere to prevent its oxidation.

圧加熱して所望の形状に一体成形する。 Next, the carbon fibers are pulled up from the molten metal. The pulled carbon fibers are uniformly coated with copper or an alloy of copper-based metal and nickel, so the desired amount is placed in a graphite die in the direction of the fiber axis. They are arranged so that they are completely random or facing a desired direction, and are integrally molded into a desired shape by heating and pressurizing them.
