SELF-SENSING AND SELF-HEALING METAL MATRIX COMPOSITES
Abstract
Achieving autonomous systems is one of the pillars of the current strategic plan of the US Air Force. Within the last two decades, a visionary AFOSR program has resulted in breakthroughs in the field of self-healing polymer matrix composites. However, to the best of the PI’s knowledge, currently there is no established technology for self-healing metal matrix composites (MMCs). Structural MMCs are among the most technologically important materials for the US Air Force missions, given their high specific strength, stiffness, and elastic modulus, in addition to remarkable fracture toughness and high temperature stability. MMCs are also perhaps among the most expensive materials to manufacture, and repair. Yet, today no established self-healing process exists for MMCs. The overarching goal of this project is to develop self-sensing and self-healing metal matrix composites (MMCs). The main innovation of the proposed research is to demonstrate a mechanism for low- temperature, low-cost and low energy self-healing of metal-matrix composites (MMCs). Specifically, we will investigate transport-mediated electrodeposition from an aqueous electrolyte in an embedded vascular system as a self-healing mechanism of a cracked MMC.
