The aim of this study was to investigate the effects of agglomerated TATB on the mechanical and sensitivity properties of cast polymer-bonded explosives (PBXs). By introducing agglomerated TATB, cast PBXs with a high solids content can be obtained. The mechanical properties of TATB-based cast PBXs were evaluated by tensile and compression tests. The experimental results showed that the addition of the agglomerated TATB clearly enhanced the ductility and fracture toughness, but decreased the strength of the PBXs. However, the strength increased with the decreasing particle size of the agglomerated TATB. When TATB-crystal was replaced by agglomerated TATB in the cast PBXs, a significant drop in the initial modulus and stress were observed. Samples with a higher content of agglomerated TATB were less sensitive to impact stimuli. The desired mechanical and sensitivity characteristics may be achieved for TATB-based cast PBXs by introducing agglomerated TATB.
