Abstract

The linear dynamic mechanical properties of plastic‐bonded explosives (PBXs) were measured from −40 °C to +50 °C over the frequency range of 0.1 Hz to 4 Hz with a Rheometrics dynamic mechanical spectrometer. The purpose of the measurements was to develop correlations between the viscoelastic properties of composite high explosive systems and their impact sensitivities. Data from drop‐skid tests using the 45°‐angled target, as performed by the Los Alamos Scientific Laboratory (LASL), were used in the sensitivity measurements. The skid‐test drop height was inversely proportional to the shear storage modulus of the PBXs and the glass transition temperature (measured dynamically) of the PBXs tested.
