PowerPoint Presentation

Composite Energetic Materials

•Topics of interests:

–Nanoscale energetic materials (nanoenergetics)

–Reactives such as Al-Teflon for application to structural energetics or reactive projectiles

–Flame spread on nanoaluminum

–Microscale combustion of nanoenergetics

•Example: Flame Spread on Nanoaluminum

–The combustion of nano-scale aluminum poorly understood

–Flame spread used as a means for characterizing the combustion of nano-aluminum with gaseous oxidizers

–J. Y. Malchi, R. A. Yetter, S. F. Son, and G. A. Risha, “Nano-Aluminum Flame Spread with Fingering Combustion Instabilities,” Presented at the 31st International Symposium on Combustion , 2006.
