Abstract

This research shows a novel in-situ experimental approach to characterize a carbon-epoxy unidirectional composite system interface. Computational models were implemented to support the experimental campaign and identify the interface properties. After validating the computational model with experimental results, it was employed to study the behaviour of interface debonding under both mode I and mode II damage. By utilizing the validated model, it becomes possible to assess the consistency of the proposed experimental approach in characterizing the interface, with the aim of generating in future an analytical model able to predict interface characteristics.
