Practical Application of Research

Foams are under consideration for use in systems designed to absorb kinetic energy from projectiles. These systems are deployed to protect internal contents, people, precious objects, and other fragile items. Foams present an attractive option because they are light, simple and fast to form, and inexpensive. This work shows that foams are capable of absorbing kinetic energy from projectiles and will eventually arrest them. Though not immediately practical, this work with ideal foams opens up the way for future studies of projectile interaction with real foams. The initial work to characterize projectile interaction with bamboo, staircase, and oblique foams will contribute to the understanding of interaction with real foams.
