Self-Healing composites for Mitigation of Impact Damage in US Army Applications

Abstract

in this study, fiber-reinforced composites with self- healing, polymeric matrices are under investigation for mitigation of impact-induced damage. Following the work of White et al. (2001) and Rule et al. (2005), the self-healing properties are engineered into the composite through the inclusion of urea-formaldehyde microcapsules containing dicyclopentadiene (DCPD) liquid healing agent and paraffin wax microspheres containing 10 wt% Grubbs' catalyst. Under low-velocity impact, it is found that self-healing materials are able to repair kissing delaminations, leading to a 51% reduction in damage quantified by a simplified visual technique. Ballistic testing using steel fragment simulating projectiles (FSPs) on composites shows damage modes comparable to the low-rate impact mechanisms. These results suggest that self-healing composites could significantly improve the survivability and sustainability of composite structures in U.S. Army applications.
