Determination of the Rheological Properties of Hydroxyl Terminated Polybutadiene (HTPB) Mixtures With Energetic Materials and Presenting Empricial Models
Rheological Properties Such as Viscosity (η), Shear Stress (τ), and Torque (M) of the mixtures of (HTPB) with Octagon (HMX), Hexogen (RDX), and 2, 6 Diamino-4-Phenyl-1, 3, 5 Triazine (DAPTA) mixtures were measured. The experimental design was arranged for three factors at two levels (High and low levels). Temperature of the mixture (°C), Speed of the stirrer (rpm), Mixing Time (minutes) have be...
متن کاملKinetic Study and Thermal Decomposition Behavior of Magnesium-Sodium Nitrate Based on Hydroxyl-Terminated Polybutadiene
This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...

بررسی روش‌های اصلاح شیمیایی ساختار پلی‌بوتادی‌ان با گروه انتهایی هیدروکسیل(HTPB)
Hydroxyl terminated polybutadiene (HTPB) is a low molecular weight polymer which has used in various industries. The good mechanical and thermal properties of HTPB based polyurethane is caused to use it as a binder for the solid composite propellants and plastic bonded explosives. Also, The presence of double bonds and hydroxyl end groups in the structure of HTPB can provide an opportunity ...
متن کاملمقایسه خواص پیشرانه‌های جامد مرکب بر پایه HTPB و NHTPB/HTPB
Hydroxyl terminated polybutadiene (HTPB) is the most commonly used binder in composite solid propellants. However, due to its non-energetic character, in practice it is just a dead weight; Therefore, replacing HTPB with an energetic polymer is essential. In this research, nitrated hydroxyl terminated polybutadiene resin (NHTPB) with 12.2% nitration rate, in combination with HTPB resin was used ...
