Composite Materials and Their Applications

Composite materials are formed by the combination of two or more constituent materials with significantly different physical or chemical properties, and are new materials with additional properties.

Composite materials are used in many applications: aerospace, vehicles and transportation, construction and infrastructure, medical, sports, leisure and entertainment, marine, defense, military, energy, electronic machinery, environmental protection and so on.

 

Application areas

1. aerospace field

In the field of aerospace, high-performance composite materials are widely used and are one of the indispensable materials. Such as aircraft wings, engine blades, spacecraft structure, etc. It has the characteristics of light weight, high strength, high wear resistance, and high fatigue resistance, which can greatly improve the performance and safety of the aircraft.

2. Vehicles and Transportation

 

Mainly in the body structure, chassis components, hood and brake system. These parts require high strength, stiffness and impact resistance, and high-performance composite materials meet these needs.

3. Buildings and Infrastructure

It mainly includes the manufacture of building exterior wall insulation board, roof board, partition wall, window and floor and other components. These materials have excellent thermal insulation, sound insulation and waterproof performance, beautiful appearance, and can improve the energy-saving performance and comfort of buildings. At the same time, it can also be used for the reinforcement and repair of reinforced concrete, improve the safety performance of buildings, and help old structures maintain their integrity.

4. medical field

Applications in the medical field mainly include artificial joints, dental implants and so on. These components require biocompatibility and good mechanical properties to improve patient comfort and safety. It can also be used to make equipment such as medical beds and wheelchairs, because these equipment has high strength and durability.

5. sports equipment field

In the field of sports equipment applications mainly include clubs, rackets, sneaker, runways, basketball stands, snowboards, surfboards and so on. These devices require high flexibility and durability to improve the competitive level of athletes, and composite materials meet these needs.

6. shipping field

The application in the field of ship mainly includes hull structure, propeller and so on. These parts require high strength, stiffness and corrosion resistance, and high-performance composite materials meet these needs.

7. Defense Military Field

It mainly includes weapons and equipment, protective armor, unmanned aerial vehicles, etc. Personal, vehicle and equipment protection takes full advantage of the advantages of composite materials: due to their inherent properties, composite materials absorb the energy dissipated. In addition, the composite material can reduce the weight loss of any protection.

8. energy sector

Among renewable energy sources, wind energy, solar panels, kinetic energy storage, water energy, tidal energy... Composite materials are used in most energy production and storage in a more environmentally friendly way by virtue of their excellent "weight ratio", good wind pressure resistance and aging resistance, and corrosion resistance. In oil and gas, harsh material environments, corrosion, extreme pressures and depths are common. Some of the problems in the industry can only be solved by using composite materials.

9. electronic machinery field

Depending on the fiber and resin selected, the composite material has dielectric, insulating, uniform, thermal and electrical conductivity properties that can be finely tuned to meet almost all requirements for electrical and electronic applications. Such as circuit boards, antennas, microwave devices, etc.

10. environmental protection field

It mainly includes sewage treatment equipment and solid waste treatment equipment. These devices require high corrosion resistance and wear resistance, and high-performance composite materials meet these needs.

Other Composite Applications

As a new material, composite materials have been widely used in various fields. With the development of science and technology, we have reason to believe that composite materials will play a greater role in the future and promote the development of all walks of life.
