Problems solved by technology

[0003] Since the reinforcement materials for automobile clutch face sheets all contain metal wires such as copper wires, the friction coefficient, wear performance, product density and burst strength of the face sheets are not very ideal, and the actual use of the face sheets leads to the failure of automobile clutches. The smoothness and wear resistance during work are not high, and the service life is short
And a large amount of copper is used, which is not only a waste of resources, but also causes serious environmental pollution.

Abstract

The invention provides a carbon fiber composite line for automobile clutch surface patch and the application thereof in preparation of an automobile clutch. The carbon fiber composite line for the automobile clutch comprises a carbon fiber long filament and a carbon fiber core spun yarn with the carbon fiber long filament as the core yarn, and does not comprise metal wires; the carbon fiber composite line also can comprise glass fiber twistless roving, a glass fiber twistless extrusion yarn and chemical fiber roving. The invention also provides the automobile clutch surface patch comprising the carbon fiber composite line. With the adoption of the carbon fiber composite line, the environmental pollution and waste of resources caused by copper wires and other metal wires in the automobile clutch are solved, and the performances of the automobile clutch are also improved.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a carbon fiber composite thread for an automobile clutch face and a preparation method and application thereof. Background technique [0002] With the development of the automobile industry, higher requirements are put forward for the supporting friction materials; especially for the quality of the clutch face in the transmission system, which is responsible for transmitting power torque, the requirements are more stringent: in addition to requiring a suitable and stable friction coefficient, relatively In addition to low wear and high burst strength, good clutch stability must also be required. The clutch face consists of rubber compound and composite fibers. In the prior art, the composite fibers for clutches all contain metal wires except chemical fibers and inorganic fibers. For example, the Chinese utility model patent (authorized notification number CN201582324U) discl...
