Method for producing carbon fiber bicycle frame

Abstract

The invention discloses a method for producing a carbon fiber bicycle frame, comprising the following steps: using carbon fibers and epoxy resin to produce a prepreg cloth; cutting the prepreg cloth according to the bicycle frame structure to form tablets; and layeredly paving the tablets on a mandrel to form a preform. According to the invention, when the prepreg cloth is produced, by mixing the carbon fibers with the epoxy resin in advance and then curing and molding after paving the preform, the epoxy resin is distributed uniformly, the binding performance between the layers of the resin can be effectively raised, and the test of the produced test piece shows that compared with a test piece produced by a traditional forming process (RTM), the shearing intensity of a test piece produced by using the prepreg cloth to conduct preform pavementcan be raised by 6%. In addition, the method can improve the bonding of the resin between the layers of the product, reduce the problem of pinholes caused by nonuniform resin existing in the products produced by the prior art, thus the product quality is raised; the preposed operation of the preform can reduce the whole process time of the produces, thus the purpose of raising the efficiency is realized.

Description

technical field [0001] The invention relates to the field of bicycle manufacturing, and more specifically, relates to a method for manufacturing a carbon fiber bicycle frame. Background technique [0002] If there are various production methods of existing carbon fiber bicycle frames, the industry mainly focuses on the research of the frame forming process; but there is little research on the prefabricated body in the last process of forming; and among the existing prefabricated bodies, epoxy resin is not used. It is easy to distribute evenly, and it is easy to produce pinholes and fine holes, which will affect product performance and reduce shear strength. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a method for manufacturing a carbon fiber bicycle frame that can improve the shear strength. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A method for ma...
