Abstract

To investigate the effect of organic fluoride on the combustion properties of aluminized HTPB solid propellant, nano and micro aluminum/organic fluoride (OF) composites (nmAl/OF and μmAl/OF) were fabricated by ball milling method. The nmAl/OF and μmAl/OF as composite additives, were added to HTPB propellant instead of aluminum powder. The effect of composite additives on the combustion performance of propellant was investigated. The nmAl/OF and μmAl/OF composites and condensed phase combustion products of propellant were analyzed by scanning electron microscope (SEM), transmission electron microscope (TEM) and particle size analysis. The results show that the nmAl/OF and μmAl/OF composite have different combination states. The heat of detonation of propellants reduces by about 2% after adding OF, nmAl/OF and μmAl/OF. The formula contained nmAl/OF has the lowest burning rate of 6.28 mm/s under the pressure of 3 MPa, and compared with the original formulation, the burning rate pressure exponent of two propellants that contained OF and μmAl/OF decreases by about 20%. The particle size (D₅₀) of condensed phase combustion product of the formulation with nmAl/OF reduces by about 47% compared with the original formulation.
