Experimental Investigation of Impacted and Non-Impacted Composite Laminates under Compressive Loading

Abstract:

In this paper, the deformation measurements of impacted and non-impacted composite laminates under compressive loading are taken. [0₃/90₃]_S orientated cross-ply laminated plates with impact delamination and without delamination are tested using an anti-buckling testing device in compression experiment. The delamination is induced by low-velocity impact test at the impact energy level of 3.105J. For both impacted and non-impacted specimens, the compressive deformation is measured by a carrier electronic speckle pattern interferometry (CESPI) optical measurement technique. It is found that the deformation behavior of the two specimens presents a mixed deformation mode. However, the delamination has significant effect on the compressive deformation of composite laminates.
