“…The first is that they find application as the binder system in plastic bonded explosives (PBXs) [1][2][3], the second as potential materials in lightweight armour systems, either as part of a composite or as a monolith. In either case, knowledge of the behaviour of these materials under high-loading rate situations is necessary such that the wider system be understood.…”

“…Quasi-static tests were performed on an Instron 5568 with a Bemco environmental chamber for temperature control; two oppositely-mounted knife-edge extensometers are used to measure the average strain as described previously [3]. The SHPB apparatus/technique has been described in detail elsewhere [4]. The DMA measurements were performed on a TA Instruments Model 2980 [5].…”

Low strain rate compression measurements of PBXN-9, PBX 9501, and mock 9501 AIP Conference Proceedings 429, 587 (1998) Abstract. The use of plastic-bonded explosives (PBXs) in weapon applications requires that they possess and maintain a level of structural/mechanical integrity. Uniaxial tension and compression experiments are typically used to characterize the mechanical response of materials over a wide range of temperatures and strain rates, providing the basis for predictive modeling in more complex geometries. After many years of data collection on a variety of PBX formulations, we have here applied the principles of time-temperature superposition to a mechanical properties database which includes PBX 9501, PBX 9502, and HPP (propellant). Consistencies are demonstrated between the results of quasi-static tension and compression, dynamic Split-Hopkinson Pressure Bar (SHPB) compression, and cantilever Dynamic Mechanical Analysis (DMA). Timetemperature relationships of maximum stress and corresponding strain values are analyzed, in addition to the more conventional analysis of modulus. The extensive analysis shows adherence to the principles of time-temperature superposition and correlations of mechanical response to binder glasstransition temperature (T g ) and specimen density. Direct ties exist between the time-temperature analysis and the underlying basis of a useful existing PBX mechanical model (ViscoSCRAM). Results give confidence that, with some limitations, mechanical response can be predicted at conditions not explicitly measured.

“…The mechanical strength of PBXs compositions depends to many variable which includes particle size and its distribution, polymer characteristics, processing method, compaction density, pressing conditions, relative humidity of storage environment, deformation strain rate, thermal history, storage and test temperature [44][45][46][47][48] , etc. In these experiments, all other constituent parameters were kept same and mechanical strength of the PBX charges was assumed to depend on mixture of TATB and HMX in the PBX compositions.…”

This paper describes formulation of plastic bonded explosives (PBXs) compositions based on 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), Octahydro l,3,5,3,5, by varying their relative amounts with Viton A as polymeric binder by slurry coating technique. These PBXs compositions are studied for mechanical and detonic properties. It has been observed that sensitivity and explosive performance of PBXs based on mixture of HMX and TATB were varied over a wide considerable range by varying relative amounts of TATB and HMX. The detonation study revealed there was increased in velocity of detonation (VOD) and detonation pressure with increasing amount of HMX from 10-80 % by weight. The sensitivity test results exhibited that insensitivity to impact for PBXs compositions was found to decrease with increasing HMX amount. Friction sensitivity study showed that no reactions were observed upto 36 kg load for PBXs compositions namely HT6030, HT5040, HT4050, HT3060, HT2070 and HT1080. The compressive strength of these PBXs compositions was found within the range of 9-11 MPa.
