Abstract
A layered composite component 100, 200 is disclosed comprising a plurality of plies of reinforcement fibres embedded in a matrix material. The component comprises a fuse region 134, 144, 157, 233, 244 in which an initiating feature 180, 190, 155 is operable to initiate delamination of plies within the fuse region 134, 144, 157, 233, 244 such that the fuse region 134, 144, 157, 233, 244 delaminates above a predetermined load condition. The component 100, 200 is operable to transition from a rigid behaviour regime to a resilient behaviour regime on occurrence of delamination within the fuse region 134, 144, 157, 233, 244.
