で、実使用に制約を受けるという問題がある。2. Description of the Related Art Fluorine resin is widely used as a sealing material because it has excellent sliding characteristics. However, fluorine resin alone is easily deformed by external force and has a large amount of wear. In order to do so, various reinforcing fillers have been blended. By the way, the use of aluminum as the mating material of the sliding material has been increasing along with the recent trend of weight reduction. In that case, the sliding material is a member filled with conventional glass fiber, carbon fiber, various metal powders or the like. If this is the case, the aluminum material of the other party is likely to be abraded, so there is a problem in that actual use is restricted.

Describes that when a very small amount of aromatic polyamide short fibers of about several percent is dispersed in a thermosetting resin, abrasion resistance is improved. However, in the combination of thermosetting resin and aromatic polyamide short fibers, the dispersibility of the aromatic polyamide fibers in the matrix resin is poor, and it is difficult to make a homogeneous sliding material, which is a problem for practical use. was there.
Further, a sliding part member obtained by firing a mixed powder of aromatic polyamide fiber and tetrafluoroethylene resin powder is known. However, similarly to the above, the dispersibility of the aromatic polyamide fiber is not always good, and it is difficult to obtain a homogeneous sliding material.

As a result, the dispersibility and mechanical strength of the aromatic polyamide fiber pulp in the fluororesin is significantly improved as compared with when the fluororesin contains aromatic polyamide short fibers, glass fibers, carbon fibers, etc. The inventors have found that the scope of application of the present invention expands and have completed the present invention.

好ましい。The present invention will be described in detail below. The aromatic polyamide fiber pulp used in the present invention means fibrillated aromatic polyamide fibers. As an index of fibrillation, there is a BET specific surface area, but the BET specific surface area of the pulp suitable for the present invention is 3 to 17 m 2 / g,
It is more preferably 4 to 15 m 2 / g. Surface area is 3m
If it is less than 2 / g, it is difficult to uniformly mix the fluororesin powder and the aromatic polyamide fiber, and the mechanical strength of the molded product is insufficient. Further, when the BET specific surface area exceeds 17 m 2 / g, the mixture becomes too bulky when mixed with the fluororesin and mixing is difficult, and it is difficult to obtain a uniform molded body,
As a result, it is difficult to obtain the reinforcing effect. The aromatic polyamide fiber used in the present invention means polyparaphenylene terephthalamide, polypara or metabenzamide, polymetaphenylene isophthalamide, or a structure thereof.
The term "fiber containing by weight" means that polyparaphenylene terephthalamide fiber is particularly preferable in terms of heat resistance and reinforcing effect.

Hexafluoropropylene copolymer resin (FEP), tetrafluoroethylene-ethylene copolymer resin (ETFE), vinylidene fluoride resin (PVDF), trifluoroethylene chloride resin (PCTFE) can be used, but among them heat resistance In terms of sliding characteristics, PTFE is preferable. The fluororesin powder has an average particle diameter of 5 to 200 μm, preferably 7 to 10
0 μm, more preferably 10 to 50 μm is used. When the average particle size exceeds 200 μm, the dispersibility of the aromatic polyamide fiber pulp is deteriorated and the strength is hard to be expressed. If the average particle size is less than 5 μm, the particles are likely to undergo secondary agglomeration, and uniform mixing becomes difficult, so that the mechanical strength of the molded product is difficult to be obtained.

It was used. These were weighed in predetermined amounts shown in Table 1 and mixed using a vertical high-speed mixer (Kakuta Super Mixer, capacity 5 l, mixing conditions 2000 rpm / 1 minute). Then, it was put into a mold having a predetermined shape and preformed under a pressure of 1000 kg / cm 2 . The preform was heated in a firing furnace by raising the temperature from room temperature to 380 ° C. over 7 hours, maintaining the temperature at 380 ° C. for about 1 hour, and then returning to room temperature over about 7 hours. The fired product obtained was cut to prepare a sample for measuring physical properties, and the sample was provided for evaluation. Among the measurement results, mechanical properties are shown in Table 1 and sliding properties are shown in Table 2. Bending strength and elastic modulus were remarkably improved and Shore hardness was also improved by filling PTFE with Twaron pulp. When the sliding characteristics of the sample of Example 2 were evaluated, the coefficient of dynamic friction was comparable to that of PTFE, and the coefficient of wear was significantly smaller than that of PTFE, indicating good sliding characteristics.

Various short fibers (chopped fibers) were used instead of the aromatic polyamide fiber pulp. Mixing of each ingredient,
Molding and preparation of measurement samples were performed in the same manner as in Examples 1-3. The evaluation results are shown in Table 1 as in the examples. The sample of the comparative example was considerably inferior in bending strength and flexural modulus to the sample of Example 2. Further, the Shore hardness varied considerably, probably because the fibers were not well dispersed in the measurement sample.
