Description of the invention (―) [Detailed description of the invention] The present invention is based on a method of manufacturing a bicycle crank, and the special M series is based on a method that uses gold fat members as internal materials. After the foam body is coated, the composite material prepreg is coated to form the heat-reformable W ', and after a few more steps, a bicycle crank with a very light Ml and a ketone impact can be completed. Bodhisattva knows that bicycle cranks are the heaviest shortcomings and are in line with the value of industrial use. 〔The present invention is back to the description〕 The space for the development of the bicycle industry in Nachi is quite large. My plaque can be said to be one of the major bicycle producing countries. * In recent years, in order to cater to the needs of modern times and face the low cost of manual labor in Southeast Asia At the same time, domestic people have also continued to move towards the direction of lightweight and mass-produced bicycles. The evolution of general bicycles is mainly from the most primitive to make # 锇 # as the main manufacturing material section to #Alum_ as the main manufacturing material • When the compound material is used as the main manufacturing material, and when K Osmium is used to produce bicycles, its eggs can be said to be quite heavy, and it is easy to cause the operator to bear on the ride. The most important shortcomings caused by Bo's use of * 戡 as the material will be changed to #Aluminum as the main policy of the Central Ministry of Economic Affairs of the Central Bureau of Industry and Economics Beigong Consumer Cooperative (please read the note on the back ^ item before filling out this page) However, K aluminum is the material used to manufacture the entire bicycle, and its volume is still quite large. Therefore, the shortcomings of r volume are too heavy. The shortcomings of J cannot be completely changed, so some people have improved the composite material as the main manufacturing material of bicycles. It is expected that although the main material of this kind of composite material is quite light, its strength is quite low, and its impact resistance and rigidity are also very insufficient. Therefore, the above problem is really impossible for bicycle manufacturers. Break through the bottleneck.
