With the rapid development of aerospace technology, the demand for high-performance aircraft is increasing, which requires materials to have the characteristics of lightweight, high strength, and high toughness.Due to its excellent specific strength and stiffness, carbon fiber composite materials (CFRP) have been widely used in aircraft body structures.

Carbon fiber composite materials are used on aircraft airframes, and ceramic matrix composite materials are used on aircraft engines. The use of carbon fiber composite materials in the field of aircraft body (including fuselage, wings, landing gear, tail wings, and other components) is constantly increasing.

Ceramic matrix composites have advantages such as light weight, low thermal expansion, high temperature resistance, and oxidation resistance, and have been recommended for use in aircraft structures that require high strength and fracture toughness. Compared with traditional engineering materials such as metals, CMC is more resistant to corrosive environments and high temperatures.
