“…for 0<Up< 1.0 mm/l.ts (1) Us = 3.10 + 1.06 Up for 1 < Uv< 2.0 mm/fas (2) where Us is the shock velocity and Ur, is the particle velocity. The technique that Munson used was to measure pressure and then calculate particle velocity for a given experiment utilizing quartz or manganin gauges, quartz up to particle velocities of 0.4 mm/tas and manganin at higher values.…”

The goal of this program was to obtain dynamic mechanical property data on a quartz phenolic (abbreviated QP) composite. Shock loading and shock release measurements have been conducted using impact techniques utilizing both a light-gas gun and a powder gun at impact pressures up to 20 GPa. The primary diagnostic tool used was a velocity interferometer. The data analysis includes Hugoniot measurements to give both pressure-particle velocity and shock velocity-particle velocity relationships; spall measurements to determine the fracture stress at which the material spalls; and attenuation measurements to determine the shock attenuation with material thickness. The QP Hugoniot relationship was found to be significantly different than that of a phenolic without a filler material indicating that the impedance of the QP used in this investigation was higher. The spall strength was measured to be-0.075 GPa, similar to nonfilled phenolic, which indicated that the presence of quartz fibers was not contributing to the fracture strength. The material was found to attenuate an imposed shock of approximately 6.3 GPa pressure and 0.18/_s to 50% of the initial impact value after a propagation distance of 7ram. *The work described in this report was performed by Sandia National Laboratories for the • United States Department of Energy under contract #DE-AC04-94AL85000.
