At this time, the vane 6 serves as a gas sealing material and receives sliding movement from both the cylinder 3 and the piston 4. FIG. 5 is a sectional view schematically showing the structure of a vane rotary compressor, in which a rotor 8 with vanes 6 rotates inside an elliptical cylinder 9, and a room divided into each bay 76 is The suction-compression-discharge operation is repeated.

た材質と摺動する際の耐摩耗性、耐焼付性に優れている
事が要求されている。In these rotary compressors, the cylinder and piston are made of different materials (for example, in the case of a rolling piston compressor as shown in Figure 4, cylinder 3 is made of soft eutectic graphite cast iron, etc., and piston 4 is made of heat-treated (In many cases, MoNiCr cast iron, etc., which has increased strength due to the use of aluminum alloys, is used.) Therefore, the vane material is required to have excellent wear resistance and seizure resistance when sliding with these different materials. There is.

In the case of a rolling piston compressor as shown in the diagram,
The cylinder 3 and the vane 6 are fitted so that the clearance therebetween is on the order of μm, and the coefficient of thermal expansion of the vane 6 is required to be close to that of the cylinder 3.

係数の点からもＡ１合金製へ−ンが用いられている。In addition, in the vane rotary type compressor as shown in Fig. 5, since the vanes 6 form part of the rotating body as described above, the input reduction effect by reducing the weight of the vanes 6 is large, and the weight of the vane material can be reduced. It is strongly required. Since automotive air conditioners are required to be lighter, the housing and compressor rotor 8 are made of AN alloy. Also from the point of view, A1 alloy horns are used.

されていなかった。However, although conventionally used iron-based materials such as high-speed steel have excellent wear resistance and a coefficient of thermal expansion close to that of the other material, improvements in weight cannot be achieved. It was needed. On the other hand, although Aj2-based materials are superior in terms of weight reduction, their wear resistance is significantly inferior to that of iron-based materials, and their coefficient of thermal expansion is quite different from that of cylinders and pistons, so they are not suitable for use in the above-mentioned automobiles. It had not been put to practical use except in the case of air conditioners.

の完成に到ったものである。The present inventors have proposed that the compressor vanes be used on sliding surfaces that require particularly wear resistance (for example, in the rollin piston type compressor shown in FIG. 4, the surface that slides on the piston 4, and as shown in FIG. 5). In the illustrated rotary type compressor, a material (A) with excellent wear resistance forms at least the central part of the surface that slides on the circular cylinder 9), and a lightweight material 1 forms the other surfaces. (B)
By creating a composite type vane in which these are combined, a vane material with excellent wear resistance and light weight can be obtained, and the materials A and B and their ratio (A/B) can be appropriately selected. The present invention was completed by discovering that the coefficient of thermal expansion can be brought close to that of the cylinder and piston.

。- High-strength carbon fibers cut into lengths of approximately 2 mm are hardened with an organic binder, and the volume of the reinforcing fibers is 20%.
This preform was fired in a non-oxidizing atmosphere to produce a molten metal forging preform, and a 4032 alloy (CAN-3i series) was molten metal forged into the molten metal forging preform. The thermal expansion coefficient of this carbon fiber FRM (hereinafter referred to as C-FRM) is due to the effect of the low thermal expansion coefficient of carbon fiber and 403
Combined with the effect of high Si content in the two alloys, the
'/'C. Using the fillet and toe of the C-FRM,
C-FR as shown in Figure 3(a) using a Schlemann extruder.
A composite material was created in which an alumina rod l was located near the end of the cross section of M2. In the above-mentioned Schlemann extrusion, after fitting the ends (la and lb) of each alumina rod 1 to each other, the alumina rods 1 having the shape shown in the second circle and having metallized surfaces are The length was made longer by joining them using root brazing. Further, after this elongated alumina rod 1 was composited with C-FRM, the joint portion of the alumina rod 1 was determined by ultrasonic flaw detection and cut at this position to obtain a composite material of a predetermined length. Next, C covering the alumina rod l
-Remove a part of the FRM and finish it by grinding and polishing it into a predetermined shape as shown in Figure 3(b).In particular, place an alumina rod in the center of the sliding surface A-1 where wear resistance is required. l was exposed.

When this composite vane is used, for example, as a vane for the birch vane rotary compressor shown in FIG. It is superior to ferrous materials such as high-speed steel, which are currently used in the industry. In addition, on the sliding surface with the rotor 8, S of the An-5t alloy matrix
