Compressive failure of fibre composites is a critical mechanism generally caused by plastic microbuckling. While the fundamentals of this mechanism are well established, applying these ideas to real structures is not straightforward, both because of the lack of data regarding fibre waviness present in such components and because it is unclear how to apply the generally idealised models of waviness to the actual random waviness distributions present. This talk presents the results of an experimental study of fibre waviness distributions in real components and a corresponding numerical study, modelling the strength of components with random fibre waviness. The effects of specimen size and free edges are highlighted.
