Abstract
The effect of slit plate design on PBXs quality was systematically studied from the point of view voids and powder‐binder separation phenomenon. PBXN‐109 type explosive samples were prepared in accordance with MIL−E‐82886 and cast through slit plates of different geometry and perforation size. The other casting parameters such as casting time, temperature, pressure, valve opening and PBX amount kept constant to prevent uncertainties arising from these parameters. Density measurements, X‐ray inspection and tensile tests were carried out to evaluate the air removal and powder‐binder separation characteristic of slit plates. Density measurements did not provide a clear interpretation of the powder‐binder separation and deaeration abilities of slit plates. X‐ray inspections and tensile tests showed that the dimensions and design of slit plate perforations have impact on voids and powder‐binder separation in PBXs. The slit plate #E showed relatively poor performance in terms of stress property, attributed to the largest cross‐sectional area per perimeter length ratio of perforations, leading to decrease in air removal ability.
期刊介绍：
Propellants, Explosives, Pyrotechnics (PEP) is an international, peer-reviewed journal containing Full Papers, Short Communications, critical Reviews, as well as details of forthcoming meetings and book reviews concerned with the research, development and production in relation to propellants, explosives, and pyrotechnics for all applications. Being the official journal of the International Pyrotechnics Society, PEP is a vital medium and the state-of-the-art forum for the exchange of science and technology in energetic materials. PEP is published 12 times a year.
PEP is devoted to advancing the science, technology and engineering elements in the storage and manipulation of chemical energy, specifically in propellants, explosives and pyrotechnics. Articles should provide scientific context, articulate impact, and be generally applicable to the energetic materials and wider scientific community. PEP is not a defense journal and does not feature the weaponization of materials and related systems or include information that would aid in the development or utilization of improvised explosive systems, e.g., synthesis routes to terrorist explosives.
