Abstract: (156 Views)

Titanium (IV) oxide as a burning rate catalyst is commonly used in some of the solid composite propellants. As the particle size of this component decreases, the final properties of the propellant will be changed. In this research, effects of using submicron titanium oxide, up to 0.5 percent by weight, have been investigated on properties of an HTPB/AP/Al propellant. TiO₂ powder has relatively spherical shape with a diameter of 300 nm. The rheological investigation performed on the propellant slurry showed that as TiO₂ particles content increased, the end of mix viscosity will be increased while pot-life has been limited. Tensile strength and elastic modulus increased by adding TiO₂, whereas the elongation reduced about 20%. Burning rate of propellant increased by an average of about 5% by adding 0.5% TiO₂ particles. Also temperature sensitivity of formulations containing TiO₂ were less than sample without catalyst. Sample having 0.1% by weight of TiO₂ has the lowest temperature sensitivity.
