Development of Carbon Fiber Composite Felt Market

 

Carbon Fiber Composite Felt is divided into two categories:

 

First, Carbon Fiber Surface Felt:

Generally 30-100 grams are the main ones, and other specifications need to be customized. Main functions:

1. Enhance the surface strength of composite materials, and play a role of lightness and strength!
2. Fill the mesh of carbon fiber cloth so that the surface of the carbon fiber products made of it will not be exposed, and the appearance will be more uniform and beautiful!
3. Carbon fiber conducts electricity!

 

Second, Carbon Fiber Thermal Insulation Conductive Felt:

Generally, PAN fiber is used as raw material, needle-punched into felt, and made through pre-oxidation, carbonization, graphitization and other production processes. It is a high-temperature thermal insulation material with excellent performance.

 

Notes:

1. When the temperature exceeds 400℃, it must be used in a protective atmosphere or in an inert gas.
2. It can be cut into any shape as needed.

 

Uses:

1. For thermal insulation: vacuum furnace, induction furnace, sintering furnace, etc.
2. For electrical conduction: electrode.
3. For heating material: carbon fiber quartz heating tube

 

Luo Yifeng pointed out that the development of high-performance carbon fiber in China is still technically difficult. This difficulty is comprehensive, both in terms of equipment and process technology. Coal tar is more complex than petroleum asphalt, and the difficulty of synthesizing carbon fiber is also greater. In addition, since high-performance carbon fiber and its composite materials are high-tech products and are indispensable new materials for the development of aerospace and cutting-edge technology, foreign countries strictly restrict the export of related technologies, which also restricts the development and application of high-performance carbon fiber in China.

 

In terms of the market, asphalt-based carbon fiber composite felt can be widely used in aerospace, aviation, aircraft, and spacecraft structural materials. The amount of carbon fiber composite materials used can account for 70% to 80% of small business jets and helicopters, 30% to 40% of military aircraft, and 15% to 20% of large passenger aircraft.

 

In addition, carbon fiber is also extremely suitable for use in sports goods, such as the long handle of golf clubs, the head of the club, the head hitting plate, etc., and its use accounts for 50% of the use of carbon fiber sports goods. For example, the use of carbon fiber for tennis rackets is about 500 tons, and the use of carbon fiber for fishing rods is about 2,000 tons.

 

Luo Yifeng said that the market demand for these carbon fibers is currently mainly based on polyacrylonitrile carbon fibers. In the market analysis of carbon fibers, polyacrylonitrile and asphalt-based should be distinguished. These two categories have their own performance indicators and their own application fields.

 

At present, high-performance asphalt-based carbon fibers have not been produced in China and are not available on the market. In foreign countries, they are basically only used in very limited fields such as satellite antennas, and are basically limited to domestic self-use. Therefore, the market demand for high-performance asphalt-based carbon fibers is still very small, and this situation will not change much in the short term.
