The feasibility of aluminium or magnalium filled fluoropolymer Viton B as an open-burn time delay was investigated. Film samples with a thickness of 245 21 m. were prepared via a slurry casting process. Fuel filler content was varied from 20 to 60 wt.%. The films retained the elastic properties of the parent polymer except that the elongation at break decreased rapidly with increasing filler content.Sensitivity tests showed that the films were insensitive to ignition by friction and impact. EKVI thermodynamic simulations showed that, for both systems, the maximum energy output is ca. 8.3 MJ kg 1 . Energy measurements indicated that the maximum energy output occurred in the range 30 to 40 wt.%. Maximum burn rates of 82 mm s 1 and 40 mm s 1 were achieved using a magnalium and flake aluminium as fuels respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
