| Abstract: |
| Objective To analyze the damage of composite laminates under low-velocity impact, in order to better predict the impact damage. Methods The RVE model including the interphase was established, based on which the macroscopic impact model was established considering the influence of impact. At last, the model was verified with test and finite element simulation. Results The variation rules of hydrogen and oxygen concentrations with time in different environments were obtained. The suitable working environment for electrochemical solid-state hydrogen sensor was found by analyzing the test data and its working life in different storage circumstances was estimated. Conclusion The impact model established from the mesomechanics level could predict the impact damage of FRP very well. |
