NextGen Aeronautics, Inc. and their partner, Virginia Tech, propose to develop a self-healing material for wire insulation using a class of poly(ethylene-co-methacrylic acid) (EMAA) and poly(tetramethylene oxide) ionomer polymers. The self-healing property of these materials is strongly correlated with the thermal processes that occur during and after damage initiation. Recent experimental results have demonstrated that penetration of the polymer by a projectile causes localized heating near the puncture. The heating then causes a localized melt elastic response which serves to close the puncture and 'heal' the polymer.

Since self-healing has already been demonstrated using these materials, the major technical challenge of this STTR effort is to stimulate the localized melt elastic response that has been shown to initiate self-healing. Our concept is to incorporate a magnetically-response phase into the insulating polymer for the purpose of causing localized heating during high-frequency excitation of the polymer. This magnetic phase will be located close to the electrical conductor. Localized heating will cause flow into the crack and, upon cooling, the crack will close over the wire and eliminate the exposure of the bare wire.
