Problems solved by technology

Its specific gravity is less than 1 / 4 of steel, but its strength is very strong, and its corrosion resistance is outstanding. It is a new generation of reinforced fibers. Carbon fiber is widely used in civil, military, construction, aerospace and supercar fields. Carbon fiber bicycles (Carbon Bike ) are mainly mid-to-high-end racing bicycles. As an emerging material, carbon fiber is mainly used in frame (carbon frame), front fork, wheel set (carbon knife rim), etc. Although carbon fiber has been widely used in bicycle components , but the existing technology has disadvantages such as complex process, low efficiency and high cost, and needs to be further improved

Abstract

The invention provides a surface repair and grinding process for a carbon fiber bicycle frame. The frame comprises a main bracket and a front fork. The front fork is mounted on the main bracket. The surface repair and grinding process for the carbon fiber bicycle frame comprises the following steps of firstly, embryo rough grinding, secondly, rough repair, thirdly, hand painting, fourthly, baking,fifthly, repair and grinding of the filling position of a frame joint, sixthly, repair and grinding treatment of the filling position of the frame, seventhly, paint spraying, eighthly, fine grindingtreatment, ninthly, bright face grinding and tenthly, good product grinding. The surface repair and grinding process for the carbon fiber bicycle frame has the beneficial effects of being simple, lowin production cost, high in working efficiency and the like and has the great economic value and social value.

Description

technical field [0001] The invention relates to the technical field of carbon fiber bicycle frame processing, in particular to a surface repairing process of a carbon fiber bicycle frame. Background technique [0002] Carbon fiber not only has the inherent intrinsic characteristics of carbon materials, but also has the soft processability of textile fibers. Its specific gravity is less than 1 / 4 of steel, but its strength is very strong, and its corrosion resistance is outstanding. It is a new generation of reinforced fibers. Carbon fiber is widely used in civil, military, construction, aerospace and supercar fields. Carbon fiber bicycles (Carbon Bike ) are mainly mid-to-high-end racing bicycles. As an emerging material, carbon fiber is mainly used in frame (carbon frame), front fork, wheel set (carbon knife rim), etc. Although carbon fiber has been widely used in bicycle components , but the existing technology has disadvantages such as complex process, low efficiency, high...
