Reactive Nano-Layered Bimetallics for Non-Destructive Debonding of Munition Components

Abstract

The U.S. Army Research Laboratory (ARL) has demonstrated that a bonded bimetallic stratified nanocomposite structure can, with a small electrical or thermal initiation, completely and quickly (<10 ms) separate two adhesively coupled surfaces. The bimetallic layers are typically composed of metals such as nickel/aluminum or titanium/aluminum that are vapor deposited onto surfaces. To date these bi-layer films have been deposited onto brass, aluminum, graphite composite, and mylar. Unlike other debonding approaches, this method allows for fast, remote and oncommand separation of structurally bonded materials. ARL has engineered the materials to create directly applied reactive nano-coatings that allow new methods of assembling and separating structural systems. The technology is being developed to meet critical design needs for development of a non-lethal frangible 155MM artillery munition.
