Abstract The flow behavior of highly viscous casting explosives in micro-channels and special shaped moulds are critical factors affecting the formations of solid propellants and explosives. In the present work, the spreading property and flow behavior of hydroxyl-terminated polybutadiene (HTPB) binders, a major component of casting explosives, on Cu

AbstractIron was coordinately linked to the hydroxyl‐terminated polybutadiene (HTPB) backbone using iron carbonyl via a ligand displacement reaction. The modified HTPB thus obtained was reddish brown in color and was characterized by GPC, FTIR, NMR, thermal, and propellant studies. No significant changes in the rheology, molecular weight, and molecular

AbstractFour different samples of ferrocene‐grafted hydroxyl‐terminated polybutadiene (Fc‐HTPB), containing 0.20, 0.52, 0.90, and 1.50 wt % iron, were synthesized by the Friedel–Crafts alkylation of ferrocene with hydroxyl‐terminated polybutadiene (HTPB) in the presence of AlCl3 as a (Lewis acid) catalyst.

Abstract The adherent behaviors of hydroxyl-terminated polybutadiene (HTPB), a typical high viscosity liquid widely used as a binder in rocket motor propellants, onto the copper (Cu) surfaces with/without the interference of Al nanoparticles were investigated by classical molecular dynamics (MD) simulations.

Abstract Free-standing nanoparticles are a ubiquitous requirement for high-efficiency catalytic applications. Here, we report the catalytic pyrolysis of hydroxyl terminated polybutadiene (HTPB) binder in composite propellant by free-standing CuO nanoparticles synthesized through a novel aqueous thermolysis synthetic route.

High volume change and low thermal conductivity will impede the application of paraffin wax (PW). Expanded graphite (EG) is one of the best materials to shape-stabilize PW and improve its thermal conductivity. NanoSiO2 is also considered as a good supporting material of PW. Herein, a novel nanoSiO2-EG-PW ternary form-stable phase change material (FSPCM)
