摘要（英）：

The invention relates to a manufacturing method of a brake lining in the automotive industry, in particular to a method for manufacturing a brake lining with silicate whisker, which can improve the porosity of the brake lining and enhance the strength of the brake lining so that the performance of the brake lining is more stable under the conditions with high temperature and high speed. In the method, the applied bonding agents are phenolic resin, silicon modified phenolic resin and butyronitrile modified phenolic resin, the applied reinforcing materials are steel cotton fiber, aramid fiber pulp, mineral fiber, ceramic fiber, aramid fiber pulp and mineral fiber, the applied friction performance regulators comprise abrasives, lubricants and stabilizers, wherein the abrasives are aluminum oxide, iron oxide, magnesium oxide and friction powder, the lubricants are graphite, sulfide and mica, the stabilizers are silicate whisker, the applied fillers for the friction performance regulators are barium sulfate, potassium titanate and magnesium oxide. The brake lining manufactured with the formula can effectively improve the porosity and the high temperature resistance of materials.
