Response of Bauer piezoelectric polymer stress gauges (PVDF) (polyvinylidene fluoride) to shock loading
Polyvinylidene fluoride (PVDF) stress gauges fabricated from high quality, biaxially stretched film, and electrically poled to high values of remanent polarization are the basis for revolutionary new gauging capabilities. In the present work, a number of PVDF films have been studied under controlled impact loading to maximum impact stresses of 35 GPa. Gauges with various degrees of polarization were studied. In the impact studies, electrical response with good fidelity was obtained to stress of 20 GPa. At 35 GPa the observed response is highly distorted. Remanent polarization is found to have a significant influence on nonlinearity and probably affects the maximum useful stress for shock gauge applications.
