| Abstract: | The ex-situ toughened and the non-toughened composite laminates were tested by using the quasi-static indentation(QSI) test method.The damage propagation and failure process of these two kinds of composite laminates were compared.The results show that the low-velocity impact damage resistance of composite laminates significantly increases due to the ex-situ toughening technique.According to the test results,the first load drop point on the contact force vs indenter displacement curve doesn't correspond to t... |
