Abstract Composites are defined as heterogeneous materials made from two or more constituents with significantly different properties. For instance, fiber-reinforced polymers are made of strong and stiff fibers embedded in a polymer matrix, what makes them ideal candidates in structural lightweight applications. One of the most common architectures in which these materials are found in structures is as stacks of composite plies, also known as laminates. Despite their excellent properties, the heterogeneity and anisotropy shown by this kind of material are responsible for the complex fracture and failure modes that they exhibit. Delamination is a very common damage mode exhibited by laminated composites and has been extensively studied in unidirectional laminates. Nevertheless, for the case of general ply-stacking configurations, like multidirectional laminates, their behaviour is not fully understood, since different damage mechanisms participate in the fracture process. An experimental campaign was carried out to evaluate the mechanical response of different angle-ply laminates under mode I and mode II fracture. In this work, we will show the experimental results and modelling efforts at different scales devoted to analyse and understand the different damage mechanisms observed and their interaction during the fracture process (e.g., delamination, matrix cracking, crack migration...).
