6. In the field of life: In our daily life, we sometimes use carbon fiber to make a variety of products, which can better ensure the longevity of the use of objects.

Introduction to Carbon Fiber

Carbon fiber refers to high-strength and high-modulus fibers with a carbon content of more than 90%. High temperature resistance ranks first among all chemical fibers. It is made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. It is an excellent material for the manufacture of aerospace and other high-tech equipment.

The three leading listed companies of carbon fiber in China are Fangda Carbon, Boyun New Materials, and Kingfa Technology.

1. Fangda Carbon.

Fangtai Precision, a subsidiary, is one of the few enterprises in China that has mastered carbon fiber technology, mainly undertaking the construction of carbon fiber projects with an annual output of 3,100 tons, of which the first phase of 1,500 tons is expected to be put into production after commissioning in October this year; The second phase will start construction after the first phase is put into operation.

2. Boyun New Materials.

The company is the company with the most complete research and industrialization chain in the field of powder metallurgy composite materials in China, and its products include aerospace carbon or carbon composite materials.

3. Kingfa Technology.

In September 2011, the total amount of the company's first phase of investment in the cave did not exceed 300 million yuan, which was used for the industrialization project of Xingduan Sunkujian with an annual output of 2,000 tons of carbon fiber and 10,000 tons of carbon fiber composite materials.

Carbon

A specialty fiber composed of the element carbon. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, and the shape is fibrous, soft, and can be processed into various fabrics, because of its graphite microcrystalline structure along the fiber axis, so it has high strength and modulus along the fiber axis. Carbon fiber has a low density and therefore has a high specific strength and specific modulus.

The main use of carbon fiber is as a reinforcing material to composite with resins, metals, ceramics and carbon to make advanced composite materials. The specific strength and specific modulus of carbon fiber reinforced epoxy resin composites are the highest among existing engineering materials.

High-strength high-modulus fiber with a carbon content of more than 90%. High temperature resistance ranks first among all chemical fibers. It is made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. It is an excellent material for the manufacture of aerospace and other high-tech equipment.

Dear, hello, carbon fiber material role: 1Lightweight:

Carbon fiber refers to high-strength, high-modulus, and simple fibrillation fiber with a carbon content of more than 90%. High temperature resistance ranks first in all chemical barriers. It is made of acrylic fiber and viscose fiber residue as raw materials, and is made by high-temperature oxidation and carbonization. It is an excellent material for the manufacture of aerospace and other high-tech equipment.

Although the development of carbon fiber production in China is slow, the consumption has been gradually increasing, and the market demand is strong. The main uses include sports equipment, general industry and aerospace, among which sports and leisure goods are the most used, accounting for about 80% to 90% of consumption. China's demand for carbon fiber has exceeded 3,000 tons per year, and will exceed 5,000 tons in 2010.

The main application fields are: mature markets include aerospace and defense fields (aircraft, rockets, missiles, satellites, radars, etc.) and sports and leisure products (golf clubs, fishing gear, tennis rackets, badminton rackets, arrow shafts, bicycles, rowing, etc.); Emerging markets include reinforced plastics, pressure vessels, building reinforcement, wind power generation, friction materials, drilling platforms, etc.; The markets to be developed include automobiles, medical devices, new energy, etc.

Carbon fiber (CF) refers to high-strength and high-modulus fibers with a carbon content of more than 90%, which are made by cracking and carbonizing organic fibers (viscose-based, asphalt-based, polyacrylonitrile-based fibers, etc.) in a high-temperature environment.

High-performance carbon fiber has a series of irreplaceable excellent properties such as light weight, high strength, high modulus, high temperature resistance, corrosion resistance, erosion resistance and sputtering, as well as good designability and compositeability, and is an indispensable strategic emerging material for cutting-edge equipment such as rockets, satellites, missiles, fighters and ships.

As a strategic new material with excellent performance, carbon fiber has a density of less than 1 4 of steel, but its strength is 5-7 times that of steel. Compared with aluminum alloy structural parts, the weight reduction effect of carbon fiber composite materials can reach 20 -40; Compared with steel metal parts, the weight reduction effect of carbon fiber composites can reach 60 -80 .

A composite material. There are many applications in the aerospace industry... The Boeing 787 is made of carbon fiber.

Carbon fiber is a fiber made of carbon, which generally contains more than 90% carbon.

There are so many applications that thermal insulation, structural materials (sporting goods, sports cars, etc.), aircraft missiles and rockets are also used.

Carbon fiber can be used to reinforce, the basic operation is to clean the cracks, stuff in the carbon fiber, and then add what glue.
