がやや高くなっている。The test results of Sample Nos. 1 to 9 are shown on the right side of Table 1. From the test results, a graph of the carbon fiber addition amount and the wear resistance is shown in FIG. 3, and a graph of the carbon fiber addition amount and the friction characteristics are shown in FIG. The test results of sample Nos. 1 to 9 are as follows:
It can be said that the friction coefficient and the wear amount are generally relatively low in the range of 5 to 30% by volume of the carbon fiber 24, and the addition of the carbon fiber 24 is less than 5% by volume. The abrasion resistance is insufficient and the effect of the addition does not appear, and the abrasion resistance is reduced. If it exceeds 30% by volume, the force of holding the PTFE carbon fiber 24 is weakened, and the abrasion resistance is reduced. When the sample No. 9 PAN-based carbon fiber 24 was added, the wear resistance was equivalent to that of the pitch-based carbon fiber, but the coefficient of friction was slightly higher.

The test results of sample Nos. 10 to 15 show that the friction coefficient is about the same as (or slightly lower than) the conventional resin-coated sliding material 10 due to the mixing of a predetermined volume% of solid lubricant composition.
In addition, the amount of wear is almost the same. As described above, if the addition of the solid lubricant is 1% or less, there is no addition effect, and
