In-plane and through-thickness properties, failure modes, damage and delamination in 3D woven carbon fibre composites subjected to impact loading

This was the first systematic study of the strain rate and pressure sensitivity of 3D reinforced composites, comprising the development of several novel experimental methodologies for unit-cell identification and characterisation of its performance. This stimulated the development of corresponding multi-scale numerical models. The research was conducted alongside significant effort undertaken by Rolls-Royce and TSB (2006-2009), to further the previously available capabilities. These findings led to two follow-up research programmes (2009-2012, 2012-2014) funded by the same sponsors, jointly exceeding £1M, as well as to another, 5-year, £1.3M, EPSRC/Dstl/BAESystems/Rolls-Royce funded research programme (EP/G042586/1, 2009-2014) on composite materials for submarines in extreme environments.
