ある。However, in order to improve dimensional accuracy, these
There is a problem that mechanical processing reduces the sliding properties, and because the strength of the fibers used for the fabric base material is low, it is difficult to obtain sufficient mechanical strength to withstand high load usage conditions as a laminated sliding member. In addition, there are other problems such as poor heat resistance and chemical resistance, making it difficult to use in high-temperature and corrosive atmospheres.

起因するものであると考えられる。Although the laminated sliding member constructed in this way exhibits much superior load resistance, heat resistance, and chemical resistance compared to the aforementioned laminated sliding member using a cloth base material such as cotton cloth, The sliding properties have not been improved in any way, and the problem that the sliding properties deteriorate after machining remains unsolved.This is extremely important for the aromatic polyamide fiber itself. If the laminated sliding member is formed by simply winding threads to which a binder is attached, there will be no binder between the threads (or if the laminated sliding member is formed by simply winding threads to which a binder is attached), there will be no binder present between the threads (or the generally used A cloth base material 1 having a structure as shown in FIG. 1. In other words, a binding material 4 is made by mixing a solid lubricant into a cloth base material 1 made of plain weave in which weft threads 2...2 and warp threads 3...3 intersect alternately. When formed by impregnating with solid lubricant (1), solid lubricant (
2) Since the binder (binding material) is not sufficiently impregnated between the threads of the fabric base material 1 and exists only on the surface, it is easily separated from the surface by the action of a high load; 2) When performing zero-machining processing, the surface is impregnated. This is thought to be due to the fact that the attached solid lubricant is removed.
