Effect of patch-parent stacking sequence and patch stiffness on the tensile behaviour of the patch repaired carbon-glass hybrid composite
https://orcid.org/0000-0002-2653-1892
Abstract In this work tensile behaviour of the patch repaired carbon-glass woven hybrid composites was investigated with patches of different stiffnesses and stacking sequences with the aid of digital image correlation and acoustic emission. Two parent hybrid laminates were repaired with eight patches constituting carbon and glass plies. The damage modes are studied to understand their effect on load recovery. The least stiff patch combination with parent laminate having exterior ply as the glass ply exhibited 24.6% higher load than the drilled specimen. The patches with glass ply facing the parent laminate showed better recovery for the same patch stiffness.

Highlights Study on tensile behaviour of external patch repaired hybrid laminates. Effect of patch-parent stacking sequence and patch stiffness was studied. Damage modes of pristine, drilled and repaired specimens were inspected visually. Displacement contours drawn from DIC, for drilled and repaired specimen were analysed. Tensile response was analysed along with the acoustic emission (AE) data.
