Product with effect diagram

Carbon fiber (CF) is a new kind of fiber material with high strength and high modulus fiber with carbon content above 95%. It is made of flaky graphite microcrystal and other organic fibers along the axial direction of the fiber pile, the carbonation and graphitization of the microcrystalline graphite material. Carbon fiber “outside the soft inside just”, the quality of aluminum than the light, but the strength is higher than iron and steel, and has a corrosion-resistant, high modulus of the characteristics of the military and civilian aspects of national defense are important materials. It not only has the inherent intrinsic properties of carbon materials, but also both the softness of textile fibers can be processed, is a new generation of reinforcing fibers.
Carbon fiber is a carbon material with strong tensile strength and fiber softness and machinability. Carbon fiber is a kind of new material with excellent mechanical properties. The carbon fiber has a tensile strength of about 2 to 7 GPa and a tensile modulus of about 200 to 700 GPa. Density of about 1.5 to 2.0 grams per cubic centimeter, which in addition to the original wire structure, mainly determined by the carbonization temperature. Generally after high temperature graphitization of 3000 , the density of up to 2.0 g per cubic centimeter. Coupled with its light weight, its weight is even lighter than aluminum, less than 1/4 of steel, iron is 20 times stronger than the strength. Carbon fiber thermal expansion coefficient and other fibers, it has the characteristics of anisotropy. The specific heat capacity of carbon fiber is generally 7.12. The thermal conductivity decreases with increasing temperature and is negative (0.72 to 0.90) parallel to the fiber direction and positive (32 to 22) normal to the fiber direction. The specific resistance of the carbon fiber depends on the type of the fiber, and at 25C, the high modulus is 775, and the high-strength carbon fiber is 1500 per centimeter. This results in the highest specific strength and specific modulus of the carbon fiber in all high performance fibers. Compared with titanium, steel, aluminum and other metal materials, carbon fiber in the physical properties of a large intensity, high modulus, low density, linear expansion coefficient and other characteristics, can be called the king of new materials.
Carbon fiber is one of the main users of carbon fiber in the field of sports and leisure, such as golf clubs, fishing rods, tennis racket badminton rackets, bicycles, ski poles, snowboards, windsurfing masts and sailing hulls. Carbon fiber used in daily necessities, such as audio, Yuba, heaters and other household appliances and mobile phones, laptops and other electronic products can also see the carbon fiber figure. [11]
Three important applications in sports are the bat and racket frames. It is estimated that the production of bat each year to 34 million. 40% of the world's carbon fiber rods are made of carbon fiber. The production of carbon fiber fishing rods around the world is about 20 million per year. The market capacity of the racket frame is about 6 million per year. Other sport applications include ice hockey sticks and ski poles. Carbon fiber is also used in boating, rowing and other marine sports.
Carbon fiber cloth, also known as carbon fiber cloth, carbon fiber cloth, carbon cloth, carbon fiber fabric, carbon fiber belt, carbon fiber sheet (prepreg cloth). Carbon fiber cloth is a one-way carbon fiber products, usually 12K carbon fiber silk weaving. Weight is the lightest 1K carbon cloth, carbon fiber frame bicycle, tripod basic use 3K carbon cloth. 1K carbon fiber pipe as a result of the grade from the carbon wire, resin composition, density of carbon cloth, molding pressure and temperature processes are very strict, 1K carbon cloth price is 3K carbon cloth 3 times. Two thicknesses are available: 0.111 mm (200 g) and 0.167 mm (300 g). Carbon fiber cloth with high strength, small density, thin thickness, the basic does not increase the weight and cross-section reinforcement components size. Carbon fiber is widely used in building bridges and tunnels and other structural types, structural shape of the reinforcement repair and seismic reinforcement and node structure reinforcement.
