The main application fields of composite materials are:
① Aerospace field. Due to the good thermal stability, high specific strength and specific stiffness of composite materials, it can be used to manufacture aircraft wings and front fuselage, satellite antennas and their supporting structures, solar cell wings and shells, shells of large launch vehicles, engine shells, Space Shuttle Structural Parts, etc.
② Automobile industry. Because the composite material has special vibration damping characteristics, it can reduce vibration and noise, has good fatigue resistance, is easy to repair after damage, and is easy to form as a whole. member.
③ Chemical, textile and machinery manufacturing fields. The composite material of carbon fiber with good corrosion resistance and resin matrix can be used to manufacture chemical equipment, textile machines, paper machines, copiers, high-speed machine tools, precision instruments, etc.
④ Medical field. Carbon fiber composites have excellent mechanical properties and do not absorb X-rays, and can be used in the manufacture of medical X-ray machines and orthopedic stents. Carbon fiber composites also have biological histocompatibility and blood compatibility, good stability in biological environments, and are also used as biomedical materials. In addition, composite materials are also used in the manufacture of sports equipment and as building materials.
