Hugoniot and reshock measurements of AngstromBond epoxy

AngstomBond AB9110LV is a common epoxy used to hold samples and targets together in shock compression experiments. The epoxy is typically applied as a thin layer between other materials of interest. While this thin epoxy layer is typically ignored in analysis, its presence affects shock propagation and pressure conditions at the interfaces, thus ignoring its presence leads to additional uncertainties and errors in an experiment. Shock compression experiments are performed here on bulk samples of AngstromBond to measure the principal Hugoniot and reshock states at various pressure conditions. The experiments were performed on a 40-mm-diameter powder-driven gun with projectile velocities ranging from 500 to 1600 m/s. The configurations included shock compression and reshock from a high-impedance window, allowing both points on the principal Hugoniot and reshock states, as well as possible reverberations to higher pressures, to be obtained. A preliminary shock Hugoniot is presented. Calculations are presented to show the effect of accounting for these AngstromBond epoxy layers in experimental configurations.
