Carbon fiber bicycle rims worth tens of thousands of dollars are produced like this

The expensive price of carbon fiber I believe many car enthusiasts know that low-end carbon fiber also needs several thousand, and the high-end price is unlimited. As for why it is so expensive, it is because carbon fiber is composed of a variety of carbon element materials, and carbon fiber is made of carbon fiber. The production process is complicated, and it is made of composite materials such as organic fibers and graphite crystallites. Due to the strength and weight of carbon fiber, the performance is better than other materials.

Because of the lighter weight and greater strength of carbon fiber, carbon fiber is widely used, both in industry and in the military. Of course, this technology is also applied to the pursuit of lightweight bicycle wheels and bicycles. Above, below, let us reveal the production process of carbon fiber wheels.

The first is to pile the organic fibers together and press them together in the same direction with a strong external force, and then place the stacked organic carbon fibers in a pre-made mold. The mold is made by concentration and requires one layer. A layer of superimposed raw materials is put into the mold.

After the raw materials in the mold are placed, the mold and raw materials are placed in an oven for high-temperature baking until the material is formed. The processed fiber elements will only increase greatly in terms of performance and general hardness.

After molding, the next step is the punching process. Punching is a very careful process, because different hole numbers require different punching data to process. If there is a slight error, then the previous efforts will be abandoned.

Not only that, the punching force of the angle of each hole must be controlled well to ensure that the products produced will not make mistakes when used, and will not cause the spokes to be unable to fit in. The hole must be carefully measured. Depth to ensure normal use when installing the hub.

The perforated wheel set needs to be surface treated. The treated carbon fiber can form a better surface, and then rinse it with a solvent, mainly to rinse off excess impurities and excess carbon filaments, and then dry after washing. After drying, a thin layer of cortex will be formed on the surface of the wheel set to play a protective role.

After the above process is completed, the finished rim can be obtained, and then the product inspection is carried out to check whether it can be delivered and whether the various indexes meet the indicators. After the various indexes are compounded, the factory will be delivered. A lightweight rim is just like this It's produced.
