Non-hazardous surrogates for high explosive (HE) materials, commonly known as “mocks,” are used in situations where the handling of actual HE is impractical or unnecessary. Conventionally, mock materials are manufactured to match only one or two properties of interest for a given HE, limiting their utility as proxies for materials research. Previous efforts to identify a suitable thermal and mechanical mock material for HMX explosive resulted in the selection of 5-lodo-2’-deoxyuridine (IDOX) which has superior properties to current mocks. To match the compressive strength and elastic modulus of HMX plastic bonded explosive (PBX) an investigation of IDOX particle size distribution dependence in formulated mock materials verse mechanical properties was conducted. Additionally, the selected particle size distributions were investigated for their batch to batch reproducibility and a pressing study to determine process/property relationships between the new mock PBX and the conditions under which it is pressed.
