Carbon fiber reinforced composite materials are materials with excellent performance produced by combining carbon fiber and other matrices through composite processes. Carbon fiber tubes are circular tube structures made of carbon fiber, also known as carbon fiber tubes, also known as carbon tubes. They are composite cylindrical shell structures. an important application. Carbon fiber tubes are made of carbon fiber composite materials pre-impregnated with styrene-based polyester resin and then heated and solidified by pultrusion (twisting). As a product of carbon fiber composite materials, it is widely used in aerospace, aviation, machinery, shipbuilding, civil construction and other fields. It not only inherits the advantages of raw materials, but also shows excellent properties that single raw materials do not have. Carbon fiber has more complete properties than conventional materials.

1. Good mechanical properties. The mechanical properties of carbon fiber are very high. The density of T300 carbon fiber tube is only about 1.6g/cm³, and the tensile strength can reach 3600Pa. This makes the carbon fiber tube have a very high lightweight advantage and outstanding mechanical properties. In addition, the carbon fiber tube It also has high fatigue resistance. Compared with pipes made of other materials, carbon fiber pipes are light in weight and have higher performance advantages. They are also used in many industries that require high lightweight, such as aircraft and automobiles. At the same time, due to their It has small creep and can also be used in the production of robotic arms, space telescope tubes, and rollers.

2. Good chemical properties, carbon fiber pipes have very good chemical stability, carbon fiber pipes still maintain good stability in the environment of acid, alkali and salt corrosion, and have very high corrosion resistance, which also makes carbon fiber pipes It can be used very well in many fields.

3. Good fatigue resistance. The composite process of composite materials makes the interface between the fiber and the matrix possess adhesive properties, so that even if fatigue wear occurs, cracks will not easily propagate, thus improving the fatigue resistance of the material.

4. Good shock absorption performance. The natural frequency of parts made of carbon fiber is higher than that of traditional parts. Therefore, the parts are less likely to be damaged and failed due to resonance; in addition, the special structure between the component materials of the composite material due to the composite process enables it to effectively absorb vibrations caused by vibration. generated energy, thereby improving seismic characteristics.

5. Good damage safety performance. The fibers in composite materials can independently bear external loads. When a part of the fibers in the material fails, the remaining fibers will evenly share the external load, so the structure can continue to bear the load.

6. Good molding process performance. When making carbon fiber, the production of materials and the shaping of components can be completed at the same time. Especially when making complex structural parts, unnecessary parts are reduced, production costs and processing errors are reduced.

7. Longer service life: Carbon fiber composite materials have good fatigue resistance. The lightweight material itself can reduce the load-bearing load of parts and has low friction. When used to rotate the roller body, even if the rotation speed is very fast, the roller body is not prone to damage. The larger deflection can effectively avoid damage to the protective layer on the surface of the roller body and the shaft head and other related parts, and reduce the cost of replacement and maintenance.
