The growing use of polymer composites in transport, sport and energy applications is leading to an increased need to solve in-service failures. Fractography, the study of fracture surface morphologies to glean information about the material microstructure and failure processes, is the principal method for achieving this.

In addition to being vital for post-mortem analysis of failed structures, fractography is u
