| Abstract Scope |
Plastic-bonded explosives (PBX) are polymer matrix composites that are highly loaded with micron-scale explosive crystals. The thermal and mechanical properties of these materials must be well-understood to develop engineering models, but testing such properties can be hazardous and expensive. A non-hazardous PBX surrogate (“mocks”) could be used in place of a PBX if the thermomechanical properties are close enough. Our previous research has shown that 5-lodo-2’-deoxyuridine (IDOX) is a promising filler material in place of the explosive HMX but that subtle formulation details are more important than originally suspected. Here, to better match the compressive strength and elastic modulus of different HMX-based PBXs, an investigation of binder composition and an expansive IDOX particle size study was conducted. We find that both variables are important for tailoring compressive properties of the bulk composite, and our ability to match the target PBX properties within acceptable deviation is validated.
