Carbon fiber bicycle disc brake base and its forming process

Abstract

The invention discloses a carbon fiber bicycle disc brake substrate and a molding process thereof. Processed cylindrical nuts with threads are embedded in two protruding legs of a prefabricated carbon fiber substrate; the substrate is placed in a mold, the cylindrical nuts are locked by screws and are fixed in a positioning mold cavity of the mold; the mold is closed and the substrate is molded; the mold is opened, the carbon fiber bicycle disc brake substrate is taken out, and the screws are unfastened, and thus the production of the integrated disc brake substrate is completed. The cylindrical nuts are embedded in the carbon fiber bicycle disc brake substrate, and are fixed by the screws, so that the carbon fiber bicycle disc brake substrate and the cylindrical nuts are integrally molded, and are excellently combined by utilizing the carbon fiber material characteristics; through the setprecision of the cylindrical nuts, the mounting size of a disc brake is ensured and the secondary processing steps are omitted; in addition, by the integrated molding mode, the damage to carbon fibers can be avoided, and the strength and the life of the disc brake substrate are effectively ensured.

Description

Technical field [0001] The invention relates to a method for manufacturing a bicycle disc brake base, in particular to a carbon fiber bicycle disc brake base and its forming process. Background technique [0002] With the continuous advancement of science and technology, carbon fiber composite materials (carbon fiber) are no longer limited to the use of aerospace. Various carbon fiber composite materials have also entered the lives of ordinary people, ranging from badminton rackets to cars. Carbon fiber composites are everywhere. The figure of the material. The strength of carbon fiber composite is higher than that of copper, but its own weight is less than that of aluminum. Compared with glass fiber, carbon fiber also has the characteristics of high strength and high modulus. It is a very excellent reinforced material and can be used as a new type of non-metallic material. To apply. [0003] Cooperate figure 1 , 2 As shown, the current common carbon fiber bicycle disc brake base...

AI Technical Summary

Problems solved by technology

Such a processing method is to carry out post-processing on the formed carbon fiber bicycle base. The drilling process will not only produce processing tolerances, resulting in poor dimensions of the product disc brake, but also damage the carbon fibers and affect the strength of the base.
