What are the advantages of Carbon Fiber?

Answer 1

1. Carbon fiber roller tube is beneficial to improve the production efficiency of machinery and equipment: carbon fiber composite material is less dense and stronger, and can reduce weight by about 70% compared with the same type of steel tube body, and about 30% compared with the same type of aluminum alloy tube body. The use of carbon fiber material to make the rollers on the paper machine equipment, in the application not only can effectively reduce the self-weight of the equipment, but also significantly reduce the movement inertia of the rollers, which is conducive to the high-speed and stable operation of the rollers, and improve the production efficiency of machinery and equipment from the whole.

2. The coefficient of thermal expansion of carbon fiber roller tube is close to zero: carbon fiber composite materials are designable and can increase the stiffness in the main direction and control the coefficient of thermal expansion through an optimized lay-up scheme according to the actual needs of the structure. For example, the optical lens barrel made of carbon fiber composite material adopts the one-to-one customized lay-up method, and the thermal expansion in other directions is offset by the thermal expansion parallel to the fiber direction, so that the thermal expansion coefficient of the component is nearly zero.

3. The product accuracy of carbon fiber roller tube is more controllable: there are various molding methods for carbon fiber composite materials, and the dimensional accuracy and surface quality of carbon fiber roller tube mainly depend on the molding process and strict product quality control. Good process level can effectively reduce the quality defects on the surface of the finished product, make it smooth and flat, and ensure the dimensional tolerance. The mechanical processing of traditional metal pipe parts has the risk of deformation, and higher dimensional accuracy is especially important for some high precision instruments and equipment. Take an antenna support rod made of hollow thin-walled carbon fiber round tube as an example. By replacing the original aluminum support rod with the carbon fiber composite tube, the dimensional stability and accuracy of the antenna are significantly improved.

4. Longer service life of carbon fiber roller tube: carbon fiber composite material has good fatigue resistance, and the lightness of the material itself can reduce the load-bearing of the parts, the weight is light and the friction is small, so when it is used for rotating the roll body, even if the speed is fast, the roll body is not easy to produce large deflection, which can effectively avoid the damage of the surface protection layer of the roll body and the shaft head and other related parts, and reduce the cost of replacement and maintenance. Carbon fiber composite material is also very corrosion resistant, and can resist the corrosion of general industrial chemicals (except strong alkali and acid), and it is easy to maintain and clean.

5. The vibration amplitude of carbon fiber roller tube is small: the stiffness of carbon fiber composite tube is much higher than that of ordinary steel tube, and using it as a roller body will produce less vibration in the high-speed operation of mechanical equipment. The carbon fiber composite roll applied on the printing machine equipment can not only achieve higher speed but also higher printing quality compared with the traditional metal roll.

6. Small deformation of carbon fiber roller tube: carbon fiber composite material has better performance in tensile, compression, bending, bending shear and torsion, etc. carbon fiber roller tube has small deformation in long-term mechanical operation, which can provide better working condition for the equipment. For example, the use of carbon fiber composite pilling rolls in textile machinery has good dimensional stability and is not easy to deform, especially in longer roll bodies, the twist deformation rate of carbon fiber composite is much lower than that of traditional steel rolls.
