Technical requirements of carbon fiber roller

I. Material selection The selection of carbon fiber roller material has a very important impact on the manufacturing process and product quality. Generally speaking, high-quality carbon fiber roller materials should meet the following conditions: 1. The quality of carbon fiber should be good, the fiber spacing should be uniform, and there should be no obvious fiber bundles, grains or inclusions. 2. Hardness should be high, at least exceeding HRC45. 3. The direction of the fiber cloth layer should be consistent with the axial direction of the roller shaft to ensure the uniformity of strength and hardness.

II. Production process The production process of carbon fiber roller is very complex, and some key requirements include: 1. The impregnation of carbon fiber and epoxy resin or other resins shall be uniform and thorough, and hollowing and bubbles are not allowed. 2. The equipment and process control in high temperature and hot environment should be accurate and reliable, so as to ensure the shape accuracy, dimensional accuracy and appearance quality of the roller shaft. 3. Pay attention to the mutual adhesion and wiredrawing strength between carbon fiber and composite material.

III. Product testing The product inspection of carbon fiber roller is also a key step in the manufacturing process. Common detection methods are: 1. Appearance quality inspection requires that the surface of the roller shaft is flat and free of depressions, burrs, bubbles, etc. 2.For diameter deviation detection, it is required that the diameter error of the roll shaft shall not exceed ± 0.02 mm. 3.For roundness deviation detection, it is required that the roundness deviation of the roll shaft shall not exceed 0.02 mm. 4. Hardness test: the hardness shall not be lower than HRC45. 5.Axial strength determination. The test strength shall be at least greater than 6 GPa. 6. determination of friction coefficient. Different materials have different friction coefficients.

In a word, the production of high-quality carbon fiber rollers requires strict control of materials, processes and testing. Only in this way can quality, performance and reliability of carbon fiber rollers be guaranteed, and at the same time, they can adapt to a variety of application scenarios.
