The aerospace field has extremely strict requirements for materials, which need to have high strength, high stiffness, low density, high temperature resistance, corrosion resistance and other properties. Therefore, the use of high-performance composite materials has become a trend. High performance composite material refers to a new type of material made by combining two or more materials together, usually consisting of a reinforcing phase and a matrix phase. The following high performance composites are commonly used in the aerospace sector:

Carbon fiber composites: Carbon fiber has high strength and stiffness, while light weight, good corrosion resistance, is commonly used in the aerospace field of reinforcement materials. Carbon fiber composite material, which consists of carbon fiber and resin matrix, is widely used in the manufacture of aircraft wings, fuselages, engine hoods and other components.

Glass fiber composite material: Glass fiber has high strength and stiffness, low price, is a stable performance of the reinforcement material. Glass fiber composite materials are commonly used in aircraft internal structure, radome and other components.

Kevlar Composites: Kevlar is a high-strength synthetic fiber with high impact and temperature resistance. Kevlar composites are widely used in the manufacture of body armor, debris shields and aircraft seats in the aerospace field.

Alumina composite material: Alumina is a ceramic material with strong wear resistance and high hardness and thermal stability. Alumina composites are often used in the manufacture of aircraft engine parts, such as turbine blades and jet nozzles.

PBO composite: PBO is a high-strength, high-modulus synthetic fiber with excellent wear resistance and high temperature resistance. PBO composites are often used to make parts such as ropes and tire wires in the aerospace field.

In general, high-performance composite materials have a wide range of application prospects in the aerospace field, which can not only improve the performance of components, but also reduce the structural weight and improve the overall performance of the aircraft. In the future, with the continuous progress of technology and the continuous innovation of composite manufacturing process, it is believed that high-performance composite materials will play a more important role in the aerospace field.
