Abstract
High speed imaging has been successfully used to capture the deformation of composite structures allowing
analysis of behaviour and failure modes. However, to capture crack propagation and delamination in greater
detail, frame acquisition must be pushed to higher and higher speeds. This presents several technical and
practical difficulties, primarily stemming from hardware limitations. In this investigation, we report the
development of an acoustically triggered high speed camera system and a demonstration of its ability to
autonomously capture composite failure at up to 1 million frames per second (fps).
