1. Fine grained composite materials. The hard fine particles are evenly distributed in the matrix, such as dispersion strengthened alloy, metal ceramic, etc.

2. Laminated composite materials. It is composed of different surface materials and core materials. Usually the surface material strength is high, thin; The core material is light and low in strength, but has certain rigidity and thickness. It is divided into solid sandwich and honeycomb sandwich.

3. Fiber composite materials. All kinds of fiber reinforcement are combined in matrix material. Such as fiber reinforced plastics, fiber reinforced metal and so on.

4. Hybrid composite materials. It is composed of two or more reinforced phase materials mixed with a matrix material. The impact strength, fatigue strength and fracture toughness of the composite materials are significantly improved compared with that of ordinary single enhancement, and have special thermal expansibility. It is divided into interlayer, interlayer, sandwich, interlayer and superhybrid.    

1. Chemical, textile and mechanical manufacturing fields. It has good corrosion resistance of carbon fiber and resin matrix composite material, can be used in manufacturing chemical equipment, textile machine, paper machine, photocopier, high-speed machine tool, precision instrument and so on.

2. Automobile industry. Because the composite material has special vibration damping characteristics, can reduce vibration and noise, good fatigue resistance performance, easy to repair after injury, to facilitate the overall forming, so it can be used to make car body, mechanical components, transmission shaft, engine cradle and its internals.

3. Aerospace. Due to the composite material thermal stability is good, than strength, high stiffness, can be used to make before the aircraft wings and fuselage, satellite antenna and its support structure, solar wings and the shell, large transport carrier rocket shell, motor shell, space shuttle structure, etc.

4. Medical field. Carbon fiber composite materials have excellent mechanical properties and non-absorptive X-ray properties, which can be used to make medical X-ray machines and orthopaedic scaffoldings. Carbon fiber composite materials also have biological tissue compatibility and blood compatibility, good stability in biological environment and biomedical materials. In addition, composite materials are used in the manufacture of sports equipment and for building materials.
