Self-Healing Composite Structures

An innovative approach to self-healing composite fabrication is proposed by Global Technology Connection along with its project team from Georgia Tech, Texas A & M and industrial partners Bell Helicopters, Boeing Rocketdyne, Goodyear. The approach addresses the short-comings of current approaches namely low strength of the healed material especially following any impact damage and fatigue-induced damage. Achieving this objective will enhance Army readiness, increase safety, and reduce maintenance labor, time, and cost. In Phase I, concept for developing a new composite with self-healing capability will be demonstrated in concert with US Army Aviation. The feasibility of such an approach will be demonstrated with suitable coupon and sub-element test specimens. The transition plan for the prototype development along with scale up issues will be fully addressed. In phase II, more extensive testing of sub-element and component testing representative of actual rotorcraft part/environment will be undertaken by partnering with US Army rotorcraft prime contractor. This testing would validate the methodology, developed in the previous phase. The demonstrated technology will meet Rotary Wing Vehicle Technology Development Approach (RWV TDA) Phase 3 Technology Objectives for improved structural efficiency and affordability
