Such sliding members are usually made by pressing a fluororesin molding powder containing a filler or no filler into a mold whose inner surface has the outer shape of the intended sliding member. It has been produced by a compression molding method in which a so-called preformed product is made by sintering in a furnace. However, with this method, it is difficult to achieve the desired dimensional accuracy, and uneven thickness tends to occur. Additional finishing processes such as cutting are absolutely necessary. Furthermore, the core mold used therein is extremely expensive, as is well known, and the amount of resin used is extremely large. For example, in the case of a tubular sliding member with an inner diameter of 30'MII, although it is said that a wall thickness of 0.5M is sufficient, as long as the compression molding method is used, dimensional accuracy, thickness unevenness, and From the viewpoint of shape retention, etc., we have no choice but to make something several times thicker. In other words, we are making a molded product with a wall thickness that far exceeds its wear-resistant lifespan, even if we use paste extrusion, which is said to be able to produce thinner molded products than compression molding. However, it is difficult to manufacture a sliding member of the above size.

In order to apply the tape to such a core mold, it is necessary to overlay the raw film to a thickness that provides a necessary life span taking into account wear and tear on the sliding surface. When the core mold is a bar material such as a round bar or a square bar, a tape-shaped raw film may be wrapped around the outer surface of the core material until the required thickness is reached. This is no different from the four stages that have traditionally been used in the production of wrapped electric wires. Once the raw film is rolled up to the desired thickness, it is heated and sintered without removing the core. Sintering is accomplished by heating to 360-400'C in a conventional heating furnace. That is, during the heating, the remaining petroleum-based auxiliary agent is volatilized, and the PTFE fine powder particles are fused and integrated with each other. At this time, the raw film undergoes some volumetric shrinkage, but since the radial shrinkage is prevented by the core, the dimensional stability is not impaired beyond the linear expansion of the core. Such a sliding layer is formed.

In the present invention, after sintering is completed, a fiber-reinforced plastic (abbreviated as FRP) reinforcing layer is integrally fixed to the outer surface of the sliding layer after cooling. The FRP used here is a composite material that uses fibrous glass, asbestos, etc. as a reinforcing material and a thermosetting plastic matrix such as unsaturated polyester, epoxy resin, or 7-ether resin. 1 itself is publicly known and commercially available.

In order to integrally fix FRP to the outer surface of the sliding layer to form a reinforcing layer, uncured FRP is wrapped around the surface of the sliding layer, and then the FRP is subjected to a hardening treatment specific to the FRP, such as at a predetermined temperature. Just heat it to . In that case, in order to ensure integral adhesion between the sliding layer and the reinforcing layer, a part of the anchor is mechanically formed on the outer surface of the sliding layer by means such as embossing prior to sintering the sliding layer. Alternatively, the outer surface of the sliding layer may be chemically treated to remove fluorine using a metallic sodium solution or the like.

Once the FRP reinforcing layer is completed as described above, the desired sliding member can be obtained by simply removing the core mold. However, if the external shape of the intended sliding member is important, it is necessary to shape it into the desired external shape by cutting or polishing before removing the core.

Wrap it a second time so as to cover the joining line (3) on the side. After winding was completed, it was heated in a heating furnace at 370° C. for 1 hour. As a result, the auxiliary agent remaining in the raw tape is expelled, and the PTFE particles are sintered between each other, as shown in the figure (c).
It became an integrated sliding layer as shown in 4).

Example 6 In Example 5, the tape-shaped PTFE raw film was
The material is rolled up several times, placed in a core molded furnace, and sintered to form a sliding layer (4), after which the outer surface has knurls as shown in Figure 5. (16) Embossing was performed, and then the reinforcing layer (5) was fixed in one piece in the same manner as described in Example 1 to produce a sliding member of the present invention.
