Composite materials and their applications

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

Composite materials are used in many application fields: aerospace, vehicles and transportation, construction and infrastructure, medical care, sports, leisure and entertainment, shipping, national defense, military, energy, electronic machinery, environmental protection, etc.

Application areas

1. Aerospace field

In the aerospace field, high-performance composite materials are widely used and are one of the indispensable materials. Such as aircraft airfoils, engine blades, spacecraft structures, 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 aircraft.

2. Vehicles and transportation

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

3. Buildings and Infrastructure

It mainly includes the manufacturing of building exterior wall insulation panels, roof panels, partition walls, windows, floors and other components. These materials have excellent thermal insulation, sound insulation and waterproof properties, have beautiful appearance, and can improve the energy-saving performance and comfort of buildings. It can also be used to reinforce and repair 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, etc. 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 of their high strength and durability.

5. Sports equipment field

Applications in the field of sports equipment mainly include clubs, rackets, sports shoes, runways, basketball hoops, skis, surfboards, etc. These equipment require high elasticity and durability to improve athletes' competitive level, and composite materials just meet these needs.

6. Shipping and shipping fields

Applications in the ship field mainly include hull structural parts, propellers, etc. These components require high strength, stiffness and corrosion resistance, and high-performance composite materials meet these needs.

7. National defense and military fields

Mainly including weapons and equipment, protective armor, drones, etc. Personal, vehicle and equipment protection exploits the advantages of composite materials: Due to their inherent properties, composite materials absorb dissipated energy. In addition, composite materials can reduce the weight penalty of any protection.

8. Energy field

Among renewable energy sources, wind energy, solar panels, kinetic energy storage, water energy, tidal energy... Composite materials rely on their excellent "weight ratio", good wind pressure resistance and anti-aging properties, and corrosion resistance, Used in most energy production and storage in a more environmentally friendly way. In oil and gas, harsh material environments, corrosion, extreme pressures and depths are common. Certain problems in the industry can only be solved through the use of composite materials.

9. Electronic machinery field

Depending on the fibers and resins chosen, composites have dielectric properties, insulating properties, uniformity, thermal conductivity and electrical conductivity that can be finely tuned to meet virtually any requirement for electrical and electronic applications. Such as circuit boards, antennas, microwave devices, etc.

10. Environmental protection field

Mainly including sewage treatment equipment, solid waste treatment equipment, etc. These equipment require high corrosion resistance and wear resistance, and high-performance composite materials meet these needs.

Other composite material application fields

As a new type of 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.
