Preparation method of integrally-woven friction material
The invention provides a preparation method of an integrally-woven hot-pressed friction material. According to the method, metal fibers, inorganic fibers and / or organic fibers are made into plied yarns; the plied yarns are woven into cloth through a multi-layer integral weaving method; the cloth is soaked in resin and then dried, so that a blank can be obtained; the blank is cut and then placed ina hot-pressing mold; hot-pressing curing is conducted to obtain a semi-finished product; and the semi-finished product is subjected to heat treatment, machining and other procedures, so that a finished product can be obtained. As the friction material takes the integrally woven cloth as a framework, the fiber content of thefriction material is high, and the resin content of the friction materialis low. The finished product is high in strength and low in hardness, has certain flexibility, and can assist in solving the problems of an existing friction material.
