| Research Abstract |
The aim of the present study was two-fold: to accurately evaluate (1) the impact interlaminar shear strength and (2) the mode II impact interlaminar shear fracture toughness of laminated composites.
The first aim was successfully accomplished by developing modified Iosipescu specimens for determining the impact interlaminar shear strength. In contrast, the second aim was not successfully achieved, because our developed impact bend test technique did not enable us to accurately determine a small impact load applied to end-notched flexure specimens. This work is still in progress to improve the measurement accuracy of the impact load.
