Reactive fluorinated composites for advanced energetic systems
Abstract
Reactive material powders containing boron or aluminum as fuels and having reduced ignition delays, accelerated burn rates and minimized yield of the condensed oxides as combustionproducts will be prepared mechanochemically. The improved ignition and combustioncharacteristics will be achieved by employing fluorinated modifiers including readily reduced metal fluorides and fluoropolymers. Only small amounts of the modifiers will be used to prepare metal-rich reactive materials. It is expected that the ignition mechanisms will be altered due to low-temperature fluorine release, disrupting composite particles and generating new surface. For both ignition and combustion, products involving boron and aluminum fluorides andoxyfluorides will be volatile, accelerating burn rate and reducing two-phase losses associated with the condensed combustion products. Ignition and combustion characteristics of the new materials will be established experimentally; new combustion mechanisms will be elucidated andused to optimize their compositions and morphology. Selected reactive material compositions will be optimized and provided for independent testing and evaluation to our US Navy collaborators.
