The Influence of Temperature Environment and Polymeric Binder Proportion on the Static/Dynamic Mechanical Properties of Polymer Materials

To comprehensively explore the impact of binder content on the mechanical properties of the Polymer bonded explosive (PBX) substitute material (Polymer-bonded Analogue Explosive (PAE)—it is renowned for its outstanding high-temperature resistance, exceptional mechanical properties, excellent chemical stability, and superior electrical insulation), a series of experiments are meticulously carried out. The dynamic and static mechanical properties, along with the microstructure of PAE, are precisely measured through the Split Hopkinson Pressure Bar (SHPB) test, static compression tests, and Scanning Electron Microscopy (SEM). The dynamic performance test outcomes clearly indicate that both the binder content (2%,…
