Abstract : The invention pertains generally to composite propellants and in particular to strengthening composite propellants through a binder-filler interaction. Composite propellants are nonhomogenous propellants and comprise primarily crystaline oxidizers and metal fuels uniformally suspended in a resin binder. The crystaline oxidizers are usually inorganic compounds, such as, ammonium perchlorate or potassium nitrate but can also be organic, for example, cyclotrimethylenetrinitramine (RDX) or cyclotetramethylenetetranitramine (HMX). The metal fuels are powders of elemental metals, such as, aluminum and magnesium. In contrast with these ingredients, the binders are organic polymers such as urethanes, polyamides or vinyl polymers. Often as much as 80 weight percent of the propellant is oxidizer along about 10 weight percent of metal fuel, thus, giving a solids loading of around 90 weight percent of the total composition.
