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...
متن کاملبررسی 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 کاملStudies on Sheet Explosive Formulation Based on Octahydro-1,3,5,7-Tetranitro- 1,3,5,7-Tetrazocine and Hydroxyl Terminated Polybutadiene
The effect of replacing hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) by octahydro-1,3,5,7-tetranitro-1,3,5,7tetrazocine (HMX) in HTPB-binder on the performance, sensitivity, thermal, and mechanical properties of the sheet explosive formulation has been studied. The maximum loading of HMX was achieved up to 78 per cent in HTPB-binder system. The velocity of detonation (VOD) of HMX-based sheet e...
