Description

technical field [0001] The invention belongs to the technical field of friction plate materials, and in particular relates to a friction plate material and a preparation method thereof. Background technique [0002] Friction materials are generally composed of mineral-based inorganic materials and organic materials, in which polymers are binders, fibrous organic and inorganic components are reinforcing materials, and powdery mineral and organic materials are fillers. These components are compounded, cured and processed to produce a braking material. With the disclosure of environmental problems caused by asbestos materials, a variety of alternative fibers have been used, such as "semi-metal" hybrid brake pads and asbestos-free organic brake pads, of which "semi-metal" hybrid brake pads are mainly made of coarse Steel fiber / steel wool is used as reinforcing fiber and an important mixture. Asbestos-free organic brake pads mainly use glass fiber, aramid fiber and carbon fiber ...
