Abstract

The invention discloses a carbon fiber composite material hand brake pulling cable and a preparation method thereof. The pulling cable is prepared from the following raw materials in volume ratio: a carbon fiber reinforcing material 55%-67%, liquid epoxy resin 30%-40%, a curing agent 1%-3%, a curing accelerator 1% and an active toughening agent 1%. The preparation method comprises the following steps: (1) mixing the raw materials according to the volume ratio to form carbon fiber tows; (2) knitting the carbon fiber tows into ropes by a rope knitting method to form a twisted cable; (3) secondarily curing the twisted cable in a curing oven; (4) mounting the secondarily cured twisted cable on a yarn loading device, adjusting the speed to be reasonable, and controlling the number of sections, with unit length, of the carbon fiber cable to form a stranded cable; and (5) treating the surface of the stranded cable by using polyurethane emulsion to form a pliable and tough protecting film. The carbon fiber hand brake pulling cable is high in specific strength and high in specific modulus, is small in coefficient of linear expansion in high-temperature and low-temperature environments, and is lighter than the traditional cable, is anti-corrosion and is easy to arrange.

Description

technical field

[0001] The invention relates to the technical field of auto parts, in particular to a carbon fiber handbrake cable and a preparation method thereof. Background technique

[0002] At present, automotive mechanical hand brakes and cable-type electronic parking systems are connected to the brake shoes through steel cables, and the car is braked by friction clamping between the brake shoe and the brake hub or the friction plate and the brake disc. Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce the performance.

[0003] In addition, because some steel wires are exposed to the air for a long time, the steel wires will be corroded and rusted, so that the mechanical properties of the steel wires cannot be fully exerted, which will affect the overall performance of the auxiliary braking mechanism and even cause danger.
