Ignition and combustion analysis of direct write fabricated aluminum/metal oxide/PVDF films

Metallized energetic composite films incorporating high mass loadings of aluminum nanoparticle fuels and metal oxide oxidizers (thermite) within a polyvinylidene fluoride (PVDF) polymer matrix were constructed via repeatable direct write additive manufacturing (3-D Printing). High speed videography, Temperature-Jump/Time of Flight Mass Spectrometry (T-Jump/TOFMS), and 2D spaciotemporal temperature mapping were used to analyze the role of...
