The developed cost effective novel binder system was prepared with readily available raw materials (NBR and DBP). The formulation of the composition was performed by varying the content of the NBR/DBP binder in the range of 14-20%. The rocket performance characteristics were determined theoretically using PROPEP and compared with those of an HTPB based propellant. The rheological, mechanical, physical, ballistic and thermal properties of the NBR/ DBP propellant were studied and compared with literature data for similar compositions based on an HTPB/dioctyl adipate (DOA) binder. The yield stress was determined by spreadibilty measurements, and indicated the superiority of this binder based propellant over existing composite propellants. It was concluded that following decreasing the content of the NBR/DBP binder in the propellant from 20 to 14%: Central European Journal of Energetic Materials ISSN 1733-7178; e-ISSN 2353-1843 Copyright © 2021 Łukasiewicz Research Network – Institute of Industrial Organic Chemistry, Poland 493 Studies on the High Performance Characteristics of an Aluminized Ammonium...

If explosive mixtures are manufactured in an insufficiently controlled manner, they contain too much ammonium nitrate and generate nitrogen oxides (NOx), which are both harmful for living organism and responsible for negative weather phenomena. However, the products from decomposition of hydrogen peroxide are only oxygen and hydrogen, which are both environmentally friendly. This paper presents the results of research on the impact of two types of aluminium powder on the detonation parameters of mining explosives containing hydrogen peroxide 60% as an oxidiser. The detonation velocities were measured by means of short circuit sensors.

{"title":"A Pressure-Dependent Plasticity Model for Polymer Bonded Explosives under Confined Conditions","authors":"Q. Wei, Xi-cheng Huang, Pengwan Chen, Rui Liu","doi":"10.22211/cejem/142512","DOIUrl":"https://doi.org/10.22211/cejem/142512","url":null,"abstract":"The safety of explosives is closely related to the stress state of the explosives. Under some stress stimulation, explosives may detonate abnormally. It is of great significance to accurately describe the mechanical response of explosives for the safety evaluation of explosives. The mechanical properties of polymer bonded explosives (PBXs) strongly depend on pressure. In this study, the mechanical behaviour of PBXs under confined conditions was investigated. It was found that the stress-plastic strain response of a PBX under high confining pressures is a combination of the non-linear and linear hardening portions. However, the linear hardening portion has often been neglected in characterizing the mechanical behaviour of a PBX under such pressures. The Karagozian and Case (K&C) model was applied to characterize the mechanical behaviour of PBXs. The numerical results demonstrated that when the confining pressure was high, the K&C model could not adequately match the experimental data due to the limitation of the damage model. Therefore, a new damage model was developed by means of considering intragranular damage and transgranular damage. This modification made it possible to introduce a linear hardening process into the original K&C model. The method proposed to describe the stress-strain results under high confining pressures was to consider the stress-plastic strain curve, including the nonlinear and linear hardening portions. The damage evolution of the original K&C model and a linear hardening model were applied for the nonlinear and linear hardening portions respectively.
