Abstract:In order to investigate the energy characteristics of RDX based boron-contained explosive,the heats of detonation (Qdet) of seven explosives: RDX/B/EVA-90/8/2,RDX/B/EVA-88/10/2,RDX/B/EVA-86/12/2,RDX/B/EVA-83/15/2,RDX/B/EVA-78/20/2,RDX/B/EVA-75/23/2,RDX/B/EVA-68/30/2 mixtures were measured by standard method of GJB772A-97-701.1,and theoretical calculation of Qdet was performed. The results show that there is a linear relationship between the heats of detonation of explosive mixtures and the boron content in the range of 8% to 20%,indicating that boron powder makes the value of Qdet of RDX increase. The measured and calculated maximum heats of detonation are 7162 kJ·kg-1 for RDX/B/EVA-78/20/2 mixture with B/O ratio of 0.87 and 8967 kJ·kg-1 for RDX/B/EVA-83/15/2 mixture with B/O ratio of 0.61 respectively. After maximum values of Qdet, with increasing the boron content,the value of Qdet decreases.

Abstract:A novel “dielectric structure pyrotechnic initiator” was proposed by integrating reactive multilayer films. The initiator sample prepared by Al/CuO-based reactive multilayer films was fabricated using standard micro electrical mechanical techniques. The dimensions of sample are of 2000 μm×2000 μm×2.6 μm and the resistances is about 4 Ω. It is found that the sample will explode completely after constant voltage has run over 60 V in open-air. The exothermic reaction of Al/CuO multilayer films was proved through analyzing the histories of current,meanwhile Cu produced by exothermic reaction results in “delayed-time discharge” of the initiator. A system based on the double-line atomic emission spectroscopy was used to obtain electrical-explosion temperature and its duration of the pyrotechnic initiators. The electrical-explosion temperature covers from 2500 K to 3500 K and its duration is 0.35 ms when the pyrotechnic initiator is discharged in 60 V. Furthermore,the electrical-explosion temperature covers from 3500 K to 4000 K and its duration is 0.55 ms when the pyrotechnic initiator is discharged in 80 V.

Abstract:A new type of ammonium nitrate fuel oil (ANFO) explosive was investigated to solve the problem of low detonation velocity, which was made of ammonium nitrate water solution, surfactant, oil by C—O—H chemical structure, and dried under vacuum condition. The microstructure, thermal stability and mechanical sensitivity were analyzed. The effect of charge density on detonation velocity was studied. The advantage of new type of explosives was also analyzed. Results show that the mixture uniformity of components and thermal stability are good. When the charge density is 0.86 g·cm-3, the detonation velocity is 4400 m·s-1. The hydrogen bonding interaction of hydrogen atom of ammonium group and carbonyl in oil, increases detonation velocity of the explosive.

Abstract:A simulated agent for liquid propellants was gelled efficiently and instantly at room temperature by modulating aggregate behaviors of a typical surfactant with the addition of a carboxylic salt in two polar solvent mixtures. An orthogonal test (three factors and four levels) was employed to investigate the factors affecting the rheological properties of the gels of the simulated agent. Results show that the significance of the factors affecting the mechanical strength of the gels follows the order of (1) the composition of the composite gelators (a surfactant and a carboxylic salt), (2) the composition of the mixture solvents, and (3) the temperature at which the gel had been prepared. However, the factors affecting the viscosity of the gel systems at higher shear rate (4355.0 s-1) follows another order, that is (1) the composition of the mixture solvents, (2) the gel preparation temperature, and (3) the composition of composite gelators. Considering the results from frequency scan and those from orthogonal test, a gel from the simulated agent having high stabilities and low-viscosity at a high shear rate was obtained. In the gel formula, the molar ratio of the composite gelators, and the volume ratio of the mixture solvents are 2:1 and 1:3, respectively, and the total mass percentage of the composite gelators is 2.4%. Moreover, the dynamic yield value and the viscosity of the gel at higher shear rate are 794.3 Pa and 13.7 mPa·s, respectively.

Abstract:The mechanical properties of a polymer bonded explosive based on HMX thermally aged under 75 ℃ were investigated. The variation of the density of the samples is less than 0.003 g·cm-3 before and after thermal aging. The results of the mechanical testing show that the compressive and tensile properties changed reversely after thermally treatment,that is,the compressive properties were dereased while the tensile properties were increased. Combined using the computer tomography (μCT),X-ray photoelectron spectrometer (XPS) and ultrasonic microscope,it shows that the density decrease of the PBX maybe resulted from the volatilization of the lower-melting-point indigent of the formulation,that is the reason for the decrease of the compressive strengh. Contrarily,the interface bonding between the HMX crystals and the binder has been improved throug the thermally aging such that the tensile mechanical properties as well as the tensile creep performance have been improved correspondly.

Abstract:In order to explore the factors affecting the size fluctuation for the variable-burning rate propellant in the co-extension process,numerical simulation method was used to simulate the flow under different operating conditions. Results show that the screw velocity fluctuation has more influence than the entrance pressure fluctuation on the size fluctuation of the variable-burning rate propellant,especially have an influence on the interface radius. The entrance pressure fluctuations have an impact on the size fluctuation of the variable-burning rate propellant,especially when the screw velocity combination is 20:30. The decrease of the entrance pressure fluctuation of the inside layer and outside layer materials, and increase of the entrance pressure of the inside layer materials properly, and reducing the solvent content of the inside layer materials and enhance the solvent content of the outside layer materials will be helpful to improve the precision of grain size for the variable-burning rate propellant.

Abstract:1,3-dipolar cycloaddition reaction was introduced. This reaction can be used in the modification of side chain of glycidyl azide polymer (GAP), cure of azides, and GAP propellant. It is shown that 1,3-dipolar cycloaddition is insensitive to water. Propellant based on this reaction can cure at 45-65 ℃. The problems of stability and compatibility between new curing age and high energy ingredient were solved, and low impact and firction sensitivity propellant could be obtained. As introduction of large group to the side chain, the mechanical property of this new propellant is relatively low. To improve this performance, modification crosslinking density and tacticity should be concerned.
