Standardized Bauer PVDF (polyvinylidene fluoride) piezoelectric polymer shock gauge
A standardized transducer that can respond to shock loading over a large stress range (0.2 to 50.0 GPa) is required for shock wave measurements. A cooperative program has been conducted among our laboratories to provide a well understood and highly reproducible standardized PVDF polymer film gauge to investigate stress wave loading and release. The polymer material source and standardized PVDF piezoelectric stress gauges are based on the work by Bauer. The shock response of standardized PVDF piezoelectric stress gauges produced by SNLA/Ktech, ISL, and commercially has been measured in controlled shock wave experiments using a compressed gas gun. Shock wave response measurements made in the 0.3 to 46.0 Gpa range show excellent agreement among gauges produced by three different facilities. These experiments demonstrated that a repeatable, well understood PVDF stress gauge can be produced if strict specifications are met. These experiments demonstrated PVDF gauges could function repeatably under severe shock loading conditions. Specific applications of this unique stress gauge are also presented. 10 refs., 5 figs., 2 tabs.
