The importance of glass shell strength becomes clear when one attempts to fill 100 carefully characterized, thin wall glass shells with a high pressure of fuel gas. Unless care is exercized in controlling the driving pressure, many of the shells will break, wasting the time and effort of characterization and losing valuable shells. KMS Fusion has pursued shell strength studies for over ten years. We have learned that when glass shells fail from excess stress (both compressive and tensile), they emit a pressure pulse. Filled shells, for example, when removed from the pressurization chamber, can be heard popping from across a room, if filled to a pressure beyond the strength of the glass walls to contain it. This pressure pulse provides a signal for detecting failure during testing. Recently Pennwalt Corporation has advertised a new piezo- and pyro-electric material it calls KYNAR/reg sign/, a thin film made of polyvinylidene fluoride. This material has unusually high piezoelectric response, and seemed a good candidate sensor to detect the buckling collapse of glass shells. 2 figs.
