Research on the Impact Damage and Fracture Behaver of Braided Composites
|
Abstract:
An experiment on the damage and fracture of the carbon fiber braided composite beam with "v" shape crack under impact load was made. The period of impact load, dynamic displacement of the beam and the history of changing strain were recorded, and distribution of strain energy was decided. Moreover, SEM photographs of composite crack was analyzed from micro mechanisms.
