Yancheng Xiangsheng Carbon Fiber Technology Co., Ltd. specializes in the production of carbon fiber powder!

Carbon fiber powder is a powder material made of carbon fiber through a special process, with many excellent properties and a wide range of applications, the following is a specific introduction:

Properties of Carbon fiber powder

High strength and high modulus: inheriting the high strength and high modulus characteristics of carbon fiber, its tensile strength and elastic modulus are excellent, which can significantly enhance the mechanical properties of composite materials, such as aircraft structural parts and other parts with high strength requirements.

Low density: the specific gravity is generally between 1.70g/ CM3-1.80g /cm3, much lower than many metal materials, can reduce the weight of objects without reducing performance, and is widely used in aerospace, automobile manufacturing and other fields, helping to improve transportation efficiency and energy utilization.

Good high temperature and corrosion resistance: can maintain stable performance in high temperature environment, can still work normally under some extreme conditions, and has good tolerance to most chemicals, is not easy to be corroded, long service life.

Fatigue resistance and creep resistance: in the process of long-term use, it can withstand repeated load and is not easy to fatigue damage, and the ability to resist the slow deformation of the material under constant stress is strong, ensuring the long-term stability and reliability of the material.

Small conductivity, heat transfer and thermal expansion coefficient: With unique electrical and thermal properties, electrical and thermal conductivity between non-metal and metal, it can meet special functional needs, such as the manufacture of conductive, thermal conductive materials and electromagnetic shielding materials, thermal expansion coefficient is close to zero or even negative, in the environment with large temperature changes, it can maintain dimensional stability to prevent material damage due to thermal expansion and contraction.

Carbon fiber powder preparation method

Mechanical crushing method: Through high energy ball mill, air mill and other equipment to strongly crush carbon fiber, but the need to accurately control the parameters, so as not to affect the performance of the powder.

Chemical decomposition method: The use of specific chemical reagents and carbon fiber reaction, so that its structure decomposition to obtain powder products, this method can produce smaller particle size, more uniform distribution of carbon fiber powder, but need to be refined to remove impurities.

Laser ablation method: With the help of high energy laser beam to vaporize the surface of carbon fiber, sublimation to form powder particles, the carbon fiber powder prepared by this method has high purity and controllable particle size, but the equipment cost is high and the production efficiency is low, and it is often used in the laboratory for small batch preparation or special fields with high quality requirements.

High temperature pyrolysis method: carbon fiber raw materials are prepared by high temperature pyrolysis, but the equipment cost is high and the operation is difficult.

Chemical vapor deposition method: by controlling the chemical reaction conditions, carbon fiber powder is deposited in the gas phase. The equipment is complex and the cost is high.

Carbon fiber powder application field

Aerospace field: The manufacture of aircraft wings, fuselage structural parts, engine components, and spacecraft structural materials, etc., can reduce the weight of aircraft, improve fuel efficiency and flight performance.

Automotive industry: Used in the manufacture of automobile body, engine cover, chassis components, transmission shaft, brake pads, etc., to help lightweight vehicles, reduce energy consumption and exhaust emissions.

Electronic and electrical fields: as electrode materials, electromagnetic shielding materials, anti-static materials, etc., used to manufacture electronic equipment shells, circuit boards, battery electrodes, etc., to ensure the normal operation and safety of equipment.

Energy field: Can be used to manufacture nickel metal hydride and nickel cadmium battery anode material conductive additives, improve the battery conductivity and charge and discharge performance.

Construction field: used to enhance the performance of concrete, improve its strength, toughness and durability, can also be used to manufacture building insulation materials, fireproof materials and so on.

In the field of sporting goods: manufacturing high-performance sporting goods such as bicycle frames, ski poles, rackets, etc., improving the durability and lightweight performance of products, and improving the use experience and competitive level of athletes.
