Abstract

The purpose of this paper is to demonstrate a novel method for the intrinsic repair of sub critical damage in complex composite structures (T-joints). First, the failure modes of CRFP T-joints subject to static and fatigue loading were established and the influence of layup and interfacial ply orientation on failure was investigated. Based on these results, a number of strategies were proposed to mitigate the extent of damage during failure and subsequently implement an in-situ repair. The ability to isolate crack paths through the tailoring of interfacial ply orientation has been demonstrated. Finally, the ability to introduce repair 'infrastructure' in the form of hollow vasculature and thermoplastic interleaves, without influencing joint strength has been demonstrated.
