Reasons for choosing carbon fiber as the keychain:
1) Carbon fiber has high axial strength and modulus, no creep, good fatigue resistance, specific heat and conductivity between nonmetal and metal Between, the coefficient of thermal expansion is small, the corrosion resistance is good, the density of the fiber is low, and the X-ray permeability is good.
2) It can be used not only as a structural material to carry loads, but also as a functional material.
3) Therefore, its development has been very rapid in recent years, in aviation, aerospace, automotive, environmental engineering, chemical industry, energy, transportation, Construction, electronics, sports equipment and many other fields have been widely used.
