Problems solved by technology

[0002] Most of the existing carbon fiber bicycle brackets are manufactured by hand lay-up process. This process consists of weaving carbon fiber filaments into cloth→resin pre-impregnation→air drying→cutting→rolling→curing→polishing→painting. The process is complicated and the production efficiency is extremely low. High cost, the product is not recyclable

Abstract

The invention provides an injection-molded bicycle frame by using a carbon-plastic material. The bicycle frame comprises a frame main body as well as a front fork, a seat stay, a left chain stay and a right chain stay which are integrally injected and molded by using the carbon-plastic material, wherein, the frame main body is composed of a left half frame and a right half frame which are respectively and integrally prepared from the carbon-plastic material in the injection molding mode. In the invention, the bicycle frame is produced by a new carbon-fiber injection molding process, wherein, the frame body is divided into the left and right parts which are respectively prepared in the injection molding mode, which belongs to original innovation of the manufacturing technology in the carbon-fiber bicycle industry, provides an effective and feasible process for large-scale and efficient production of carbon-fiber bicycles and realizes successful application of cladding and granulating and injection molding processes to production of the bicycle frame. The process has the advantages of accelerating popularization of the carbon-fiber bicycles in China with low fabrication cost so that the bicycles become popular commodities, promoting development of the carbon-fiber bicycle industry in China and providing rich experience for development of subsequent carbon-fiber products.

Description

technical field [0001] The invention relates to a carbon fiber bicycle, in particular to a bicycle frame formed by injection molding of carbon plastic material. Background technique [0002] Most of the existing carbon fiber bicycle brackets are made by hand lay-up process. This process is made of carbon fiber filaments into cloth → resin pre-impregnation → air-drying → cutting → rolling → curing → grinding → coating, the process is complicated, the production efficiency is extremely low, The cost is high and the product cannot be recycled. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is aimed at the deficiencies of the prior art, and proposes a bicycle frame made of carbon plastic material with high production efficiency and low cost. [0004] The technical problem to be solved by the present invention is achieved through the following technical solutions, a bicycle frame made of carbon plastic material, which is characte...
