Infrared Signature of Novel Super-Thermite (Fe2O3/Mg) Fluorocarbon Nanocomposite for Effective Countermeasures of Infrared Seekers

Abstract

Infrared (IR) guided missiles are real threat; they caused 90% of aircraft damage. Fluorocarbon polymer nanocomposite based on super-thermites can offer superior thermal signature to countermeasure IR guided missile seekers. This study reports on the sustainable fabrication of mono-dispersed colloidal Fe2O3 nanoparticles with 3 nm average particle size. Fe2O3 nanoparticles were dispersed in acetone for subsequent integration in fluorocarbon polymer. The impact of Fe2O3 content on thermal signature was evaluated using (FT-MIR 2–6 μm) spectrophotometer. Nanocomposite polymer with 8 wt% Fe2O3 offered an increase in the average intensity of α (2–3 μm) and β (4–5 μm) bands by 50 and 85% respectively to that of reference formulation. Quantification of stimulated emitting species in the combustion flame was conducted using ICT thermodynamic code. The developed nanothermite particles extended the primary reaction zone by 183%. Full discussions about combustion zones with associated exothermic chemical reactions have been represented.
