Case ID: C11547 Description Solid Structural Component with Controllable Fragmentation and Reactivity Novelty This technology features the ability to control the size and reactivity of fragments that result from the ignition of munitions and is useful in a variety of defense and military applications. Value Proposition Solid metal structures in most munitions do no fragment in a controlled manner. Often, very small particles are obtained. One can pattern the solid structure to improve fragmentation but this may be challenging for reactive structures. This technology allows one to control the mechanical strength of the solid structure and the size and reactivity of the resulting fragments. Analysis of reacted structures shows an improved particle size distribution. Advantages Control of mechanical strength and fragment size distributions Enhanced bonding of fragments during consolidation, compared to other methods, without the use of a glue or binding element Offers control over geometry and reactivity of fragments Technical Details JHU researchers have developed a method to design and fabricate metallic structures that fragment into particles of specified geometries and reactivity. The fragments of pre-determined sizes and reactivity are fabricated in an initial set of processing steps and then they are mechanically consolidated, through a technique called "swaging," into a solid, structural cylinder. This structure possesses the property of breaking into fragments of said pre-determined sizes upon detonation or impact. The ability to design reactive structures that fragment into particles of known geometries has been demonstrated, as has the ability to design the sensitivity or reactivity of those fragments. This technology is novel in its capacity for producing structures that fragment into particles of both controlled geometry and reactivity. Looking for Partners To develop and commercialize this novel technology in defense and military applications.
