About the application

When the spacecraft is flying in the atmosphere at high speed, it will withstand extremely high temperatures, even exceeding 2000℃. Materials with excellent thermal conductivity and high-temperature resistance are necessary.
The C/C composite materials made of mesophase pitch-based carbon fiber can be used for the rocket nozzle, engine nozzle, combustion chamber, and other parts to ensure the normal operation. Moreover, the pitch-based carbon fiber is extremely light in weight consequently effectively increasing the range of the aircraft while ensuring strength. It is the best choice for the structural material of the spacecraft.

To improve the whole level of the aircraft manufacturing and safety, economy, future aircraft manufacturing more tends to select high-strength, high-modulus, lightweight composite materials.

Mesophase pitch-based carbon fiber is suitable as lightweight robot arm material because of its high modulus and lightweight. In particular, due to the robot arms that transport large substrates have a length of 4 meters or more, during the handling process, it is necessary for arms to move up and down, flip, and do other complicated actions. The need for completing the specified actions quickly and accurately makes high modulus material vital.

As the thin-film manufacturing and the printing industry are developing towards wider dimensions and faster-operating speed, material stability plays a more essential role. Fluctuations caused by overhanging and swaying in the case of ultra-high width or high-speed rotation are nearly unavoidable, product quality negatively impacted as the consequence.
The mesophase pitch-based carbon fiber has been widely used in large industrial rolls due to its excellent dimensional stability and high temperature and corrosion resistance. It has also proven to be the best material for industrial rolls.
Pitch-based carbon fiber is expected to be necessary for the fast-growing development of flexible display, flexible solar cells, flexible chips, and other printed electronics industries.

The automobile drive shaft made of mesophase pitch-based carbon fiber not only has the characteristics of high strength and light weight, but also has small deformation and can ensure rapid and stable rotation.

As environmental problems become more serious, energy conservation and environmental protection are more concerned by the public. The lightweight of an automobile is one of the best solutions which are generally accepted.
Carbon fiber composite materials can be applied to automotive parts, interior trim, engine structures, brake systems and more else. The materials not only improve overall strength and impact resistance, fatigue resistance but also greatly reduce the weight of the vehicle, greatly reducing energy consumption. Safer, more economical, and more environmental-friendly.

With the advantages of the lightweight, superior carrying capacity, good antiknock performance, and designability, the market share of carbon fiber composite gas cylinders are getting higher. Because of high modulus and small elongation at break, the mesophase pitch-based carbon fiber is better compatible with the metal matrix, making the composite gas cylinder more processable, stable and safe during use, thus having greater potential.

Due to the light weight, high modulus and high toughness of pitch-based carbon fiber, it is widely used in sporting goods such as golf clubs, fishing rods, bicycles and tennis rackets.

The brake disc converts the kinetic energy of the car into heat by friction and releases it into the atmosphere, which requires materials with good friction and heat resistance. Compared with general metal parts, the C/C composite material made of mesophase pitch-based carbon fiber has greater advantages due to good friction performance, good heat dissipation performance, high strength, and lightweight.

More carbon fiber fabrics are used for reinforcing and repairing buildings. Its advantages may vary (e.g. high strength, good durability and corrosion resistance, lightweight, and convenient construction). However, most of the PAN-based carbon fiber cloth currently used has some flaws. For instance, the tensile modulus is relatively low, so in practical application, to exert a large strength the carbon fiber cloth needs a large deformation. The reinforced carbon fiber cloth is often used with a steel bar, and when the steel bar reaches the yield strength, the PAN-based carbon fiber does not exert the full strength because of high elongation at break. Thus, the strength of carbon fiber can’t be fully utilized. The mesophase pitch-based carbon fiber has a low elongation at break, making up for the shortcoming and contributing to building reinforcement.

As electronic devices become smaller and thinner, the materials with high thermal conductivity are becoming more important. Mesophase pitch-based carbon fiber has a thermal conductivity of more than 800 W/m• k, which is twice as much as copper and MPCF. It is one of the best materials for thermal conductivity in existing material fields. It can effectively solve the problem of electronic circuit’s heat dissipation.
The chemical heat exchanger reinforced with mesophase pitch-based carbon fiber can has good corrosion resistance, high temperature resistance and excellent thermal conductivity.

Photovoltaic power generation converts light energy into electrical energy, and the absorption of light is the main energy source. However, long-time sunshine will inevitably cause a sharp rise in the temperature of some photovoltaic substrate components, and how to dissipate heat quickly is one of the main issues to be considered. Mesophase pitch-based carbon fiber has a very high thermal conductivity and is expected to solve this problem.

Mesophase pitch-based carbon fiber has a high thermal conductivity and can be used for the top collector of the electric car.
