Abstract

The potential to redirect propagating delaminations in skin-stringer configurations away from critical failure paths and into dedicated self-healing zones has been experimentally investigated. Thermoplastic interleaves (for redirection) and a vascular network (for redirection and to ameliorate the damage) have been embedded into the structure. A variety of interleave - vascule configurations have been investigated, all successfully redirecting the propagating fatigue damage into the vascular network. The injection of a self-healing agent (low viscosity epoxy) into the vascular network demonstrated recovery of mechanical properties.
