Abstract

The invention relates to a manufacturing method and a structure of a carbon fiber wheel rim. The manufacturing method comprises the following steps of: heating a substrate to reach a temperature where the substrate can be plasticized, performing extrusion forming to obtain a strip body of a desired shape, wherein the strip body comprises two side walls, a connecting wall connected between the opposite end surfaces of the side walls, and an inner annular wall connected between the radial inner edges of the side walls, and enclosing a space among the two side walls, the connecting wall and the inner annular wall; then, joining the two ends of the strip body into a circle shape to form a wheel rim skeleton blank body, performing milling to enable a plurality of through holes to be formed in the two side walls of the wheel rim skeleton blank body or the two side walls and the inner annular wall, and forming a wheel rim skeleton; subsequently, performing a roughening procedure on the surface of the wheel rim skeleton, then covering a carbon fiber cloth material which is cut into a preset shape on the rough surface of the wheel rim skeleton, and performing heating for shaping; and finally, performing surface treatment to obtain the carbon fiber wheel rim which is light in weight and good in structural strength.

Description

technical field [0001] The present invention relates to a manufacturing method and structure of a carbon fiber rim, in particular to a method of coating a carbon fiber cloth on the surface of a rim skeleton body that has been milled with a plurality of through holes, so as to obtain a carbon fiber rim with good structural strength but Lightweight rims. Background technique [0002] In addition to being used as a basic means of transportation, the use of bicycles also has multiple functions such as leisure and sports. Coupled with the improvement of research and development capabilities and the advancement of technology, the appearance, riding comfort, body strength, weight, and speed of bicycles have become the focus of development; especially for bicycles used in professional competitive competitions, riding comfort, body Strength, weight, and speed are definitely the goals pursued by drivers. [0003] In order to make bicycles develop towards the direction of lightweight...
