An Experimental Study for the Fatigue Damage of a Carbon-Fiber Composite Suspension Bracket |
| |
| Abstract: | Fatigue testing for a suspension bracket made of carbon fiber composites is reported. Testings for fatigue life under spectrum loading, impact damage, damage expanding and for residual strength are involved, where damage examining is based on ultrasonic attenuation method. Testing results are compared with what are found in residual stiffness and strength testings. |
