| Abstract: |
| The work aims to study the impact resistance of woven composite thick laminates at room and low temperature. By carrying out the low-velocity impact test and post-impact compression test, the impact response curves, impact damage appearance, compression failure mode and residual compressive strength were analyzed and the effect of ambient temperature on the impact resistance of woven composite thick laminates was explored. The woven composite thick laminates after impact had many impact failure modes, such as pitting, delamination, matrix crack and fiber fracture, and the compression failure mode was truncation failure crossing through the impact damage area. The low temperature environment enhances the strength of the matrix, reduces the impact damage degree of composite material, and thus increases the residual compressive strength of the woven composite structure. The results of this study can provide references for the application in ice zone of the woven carbon fiber reinforced thick composite laminates. |
