Compared with metal materials, carbon fiber composite material has many excellent properties, applied to the automobile has obvious advantages, mainly in :
1. small density, high strength, CFRP in common materials specific strength and specific modulus is the highest, with dry body and chassis can reduce the weight of the car at the same time without loss of strength or stiffness, automobile safety factor is not reduced.
2. Good toughness, good impact resistance and energy absorption capacity, dry body and its structural parts have good collision safety.
3. High damping, good anti-vibration performance, used for body, transmission system and engine parts with good vibration reduction, sound insulation effect, improve the ride comfort.
4. Excellent anti-fatigue performance, used to withstand fatigue load of auto parts can effectively extend their service life.
5. Excellent heat resistance, corrosion resistance and radiation resistance.
