Thermal and combustion behaviors of aluminum/manganese dioxide/fluoroelastomer terpolymer nanothermite

open access: yesEngineering Reports, 2023
Fluoroelastomer has received increasing attention for energetic materials application due to its high fluorine contents. Different contents (0 wt%–30 wt%) of poly(VDF‐ter‐HFP‐ter‐TFE) terpolymer are added into Al/MnO2 nanothermite.

Role of redox reactions involving interfacial oxygen migration in ignition of nanolayered Al/a-Al2Ox/CuO energetic composite

open access: yesChemical Engineering Journal Advances, 2022
Thermite reactions of nanoparticles involve complex interplays between phase transition and heterogeneous atomic diffusion, especially at the early stage where the temperatures are relatively low and the systems remain as condensed phases.

Additively manufactured reactive material architectures for exothermic brazing

open access: yesAdditive Manufacturing Letters, 2021
Exothermic brazing uses the heat generated by an exothermic reaction to melt and flow filler material, but generally involves complex fixtures placed around the joint to hold the energetic material in place. Additive manufacturing can replace the fixture
