Carbon fiber tube, also known as carbon fiber tube, is a tubular product made by combining carbon fiber and resin. The common production methods are carbon fiber prepreg rolling, carbon fiber wire pultrusion, winding and so on. In the production process, we can make different types and sizes of carbon fiber tubes according to the adjustment of the mold. In the production process, the surface of carbon fiber tube can be beautified. At present, the surface of carbon fiber tube is in the form of 3K matte plain, matte twill, bright plain, bright twill and so on. How about the specific performance of carbon fiber tube, the following Shandong Interi new material to give you a brief introduction.

What are the characteristics of carbon fiber tubes?

Carbon fiber tube is the main material for carbon fiber, carbon fiber tensile strength, soft easy processing, especially the mechanical properties are very excellent. Carbon fiber has high tensile strength and light weight. Compared with other high performance fibers, carbon fiber has the highest specific strength and specific modulus. The composite of carbon fiber and resin matrix is the best in terms of specific strength and specific modulus.

The specific strength of carbon fiber resin composite material, that is, the ratio of the strength of the material to its density can reach more than 2000MPa, commonly used low carbon steel only in 59MPa, its specific modulus is also higher than steel. So in general, carbon fiber tube has the advantages of high strength, wear resistance, acid and alkali resistance, light weight and so on. In addition, the product has a series of excellent properties such as size stability, electrical conductivity, heat conduction, small coefficient of thermal expansion, self-lubrication and energy absorption and earthquake resistance. It has many advantages such as high specific modulus, fatigue resistance, creep resistance, high temperature resistance, corrosion resistance and wear resistance.

Specification of carbon fiber pipe

Carbon fiber tube generally has square tube, round tube, special-shaped tube and other forms. Processing methods are rolling, pultrusion, winding, the surface can be divided into plain, twill, pure black, and can also be processed into matte and light two forms. Commonly used carbon fiber tube diameter between 5 to 120 mm, up to 10 meters, thickness is generally 0.5 to 5 mm earlier.

The quality of carbon fiber tubes is greatly affected by the porosity, and the interlaminar shear strength, bending strength and bending modulus are greatly affected by the void. The tensile strength decreases slowly with the increase of porosity. The tensile modulus is little affected by porosity.

Application of carbon fiber tube:

1, using its light and strong and light and hard mechanical properties, widely used in aviation, aerospace, construction, mechanical equipment, military, sports and leisure, and other structural materials.

2, the use of corrosion resistance, heat resistance, good verticality (0.2mm), and high mechanical strength characteristics, so that the product is suitable for the transmission shaft of circuit board printing equipment.

3, using its fatigue resistance, applied to the helicopter blade; Using its vibration attenuation, applied to audio equipment.

4, the use of its high strength, anti-aging, anti-ultraviolet, good mechanical properties, suitable for tents, building materials, mosquito net, lifting rods, ball bags, bags, advertising display frames, umbrellas, sail, fitness equipment, arrow shaft, cue, golf practice net, flagpole switch bolt, water sports equipment and so on.

5, the use of its light, good toughness characteristics, so that the product is suitable for kites, flying saucers, bow back, electric aircraft, and all kinds of toys, etc.
