Carbon Composite Bolt and Nut

Carbon Composite Bolt and Nut usually have a standard thread shape and precise dimensional specifications, and their advantages are obvious.

Excellent specific strength and specific modulus

The strength and stiffness per unit weight are excellent. Compared with traditional metal bolts and nuts, it can greatly reduce the structural weight while ensuring the connection strength.

Good corrosion resistance

They are not easy to rust or be corroded in harsh environments such as humidity, acid and alkali. And can maintain the reliability of connection for a long time, such as in the application of marine engineering equipment.

Low coefficient of thermal expansion

In the environment with large temperature changes, they can effectively avoid the connection loosening or loss of pre-tightening force caused by thermal expansion and contraction. They ensure the stability of the connection.

Certain electrical and thermal conductivity

They can meet special requirements in some parts that require electrical connection or heat dissipation function. Such as playing a role in the installation and connection of power equipment.

Good vibration and noise reduction performance

They can absorb and attenuate mechanical vibration and noise, improve the stability and comfort of equipment operation.

Types of Carbon Composite Bolt and Nut

Carbon composite bolts and nuts mainly have the following categories.

According to the base material classification

Resin based carbon composite material bolts and nuts

With good insulation and molding process, relatively low cost, you can widely use them in general industrial fields and electrical conductivity requirements are not high occasions.

Metal-based carbon composite bolts and nuts

They combine the toughness and electrical conductivity of metal and the high strength characteristics of carbon fiber. This is suitable for electrical connection parts requiring both high strength and certain electrical conductivity.

Ceramic carbon composite bolts and nuts

High temperature resistance, wear resistance is outstanding. You can often use them in high temperature furnace, aircraft engine hot end parts and other extreme high temperature environment fastening connection.

According to the manufacturing process classification

Wound molding bolts and nuts

They have fiber distribution uniform, high strength. You can often use them in the mechanical properties of the critical aerospace components.

Molded bolts and nuts

They have high shape and size accuracy, fast production efficiency. And they are suitable for large-scale industrial production to meet the batch demand of automobile and other industries.

Uses of Carbon Composite Bolts and Nuts

Carbon composite bolts and nuts are widely used.

In the aerospace field

You can use it for fastening aircraft fuselage structural parts, wing connections, engine parts, etc.. It can reduce the weight of the aircraft at the same time to ensure the reliability and safety of the connection under high altitude flight. And improve the performance and fuel efficiency of the aircraft.

In the automotive industry

You can apply it to the connection of engine, chassis, body frame and other components. This  contributes to the lightweight design of the car, improves the handling performance and fuel economy. And it ensures the stability and durability of the connection parts during the long-term operation of the car.

In terms of sports equipment

Such as high-end bicycles, racing cars, golf clubs, etc., the equipment can be lightweight and high strength. And improve the competitive performance of athletes;

In the wind power generation equipment

You can use it to connect the wind turbine. It can withstand the alternating load and vibration under the action of wind. And ensure the stable operation of the power generation equipment. While reducing the maintenance cost of the equipment.

In the manufacture of electronic equipment

As a fastening part of precision instruments, computer motherboards, etc., you can use its low expansion coefficient and certain conductivity to ensure the reliable connection and normal operation of electronic components under temperature changes and electrical environment.
