| Abstract: |
| Objective To analyze the damage of composite laminates under different impact and to verify the rationality and validity of the finite element model. Methods Drop hammer impact test machine was used for the CCF300 /10128H fiber resin matrix composite laminates, after that, Ultrasonic C-scan was used to scan the test piece. And then a finite element model was established, ABAQUS was used to simulate the impact process. Results The results of finite element simulation were in good agreement with the experimental results. Conclusion The internal damage rapidly increased with the increasing impact. When penetrated damage occurred, the damage became mild, and the finite element could relatively well predict low-impact damage of composites. |
