Tapering composite laminates requires terminating plies, i.e. dropping-off fibre reinforced layers. Ply terminations generate through-the-thickness stress discontinuities and this promotes delamination. Extensive research has been focused on the onset and growth of delaminations from ply drop-off. This paper addresses the experimental characterization of quasi-isotropic asymmetrically tapered laminates loaded in axial tension. A high-speed camera has been used to capture the location of ply de-bond initiation and the subsequent delamination propagation. The experimentally assessed strength has been compared to the failure loads predicted employing an existing analytical method and finite element analysis based on the virtual crack closure technique.
