Abstract

A face/core debond in a sandwich structure may propagate in the interface or kink into either the face or core depending on the mode-mixity of the loading. This study explores experimental methodologies for mapping the kinking behavior at various mode-mixities. Further, it is shown that the crack kinking behavior may be altered / avoided by changing the interface design by using Chopped Strand Mat (CSM), Continuous Filament Mat (CFM) and woven mats at the face/core interface as sources for fiber bridging, thus keeping and arresting the crack in the interface.
