Detonator response measurements with a standardized piezoelectric polymer (PVDF) guage
Over the last few years, there has been considerable work in progress to study the features of the piezoelectric polymer film polyvinylidene fluoride (PVDF) under high pressure shock loading. Although full characterization of the material is not complete, it is clear that if the material is prepared with careful attention to the mechanical processing (stretching) and to the electrical processing (electrical poling), that highly reproducible responses can be achieved to shock pressures of over 40 GPa. The purpose of the present study is to characterize the shock-compression response of a 1 mm /times/ 1 mm active area (PVDF) gauge that is subject to standardized gauge-preparation processes. The shock response is studied in both compressed-gas gun, controlled impact loading and in detonator loading configurations. In the present paper, a brief summary of standardization processes will be described followed by a description of the controlled impact loading and the detonator-response measurements. 14 refs., 6 figs., 1 tab.
