Abstract

PURPOSE:To obtain easily and inexpensively an excellent bearing and sliding material utilizing the characteristics of carbon fibers by coating the carbon fibers with a metal such as Cu or Ni or the alloy thereof and soldering such fibers to a backing metal. CONSTITUTION:The metal such as Cu or Ni or the alloy thereof is coated on the carbon fibers by a method such as plating, thermal spraying or vapor deposition and such fibers are soldered to the backing metal such as cast iron, steel or copper alloy. The carbon fibers are thereby easily and thoroughly joined to the backing metal, by which the bearing and sliding material utilizing the characteristics of the carbon fibers, such as high-temp. strength, low cost and excellent wear resistance is obtd.

まれている。DETAILED DESCRIPTION OF THE INVENTION Today, carbon fibers and glass fibers occupy an important position as composite materials. Above all, carbon fiber is highly heat resistant,
It is lightweight and has great strength at high temperatures, making it an important part of aircraft. In addition, carbon fiber also has the characteristic of having a small coefficient of friction. Wear resistance is especially important for bearings and sliding parts. Therefore, there have been many examples of using carbon fiber for these parts. That is, they include composites of carbon fiber and polymer resin, carbon fibers plated with various metals and alloys, and sintered. However, the former type has poor high-temperature strength, and the latter type is expensive, preventing its practical use.

It has been found that the two can be easily joined.
