Description
To enable the use of additively manufactured polymer materials as structural and insulating components within high voltage pulsed power systems, better understanding of material compatibility with common pulser material environments is required. The present work examines the effect of long-duration contact of printed polymeric components with three high voltage insulating oils: Diala, Luminol, and Royco 66. Test pieces printed using stereolithography (SLA) were evaluated for changes in mechanical properties and dielectric strength after submersion in insulating oil for a nine-month duration. Test pieces printed using fused deposition modeling (FDM), also submerged in oil for a nine-month duration, were evaluated for changes in mechanical properties only, due to known problems with highly anisotropic dielectric strength. GC-MS was used for oil composition analysis on neat and plastic-exposed oils to identify any chemical leeching that occurred during the exposure period and to correlate changes in chemical composition with bulk mechanical and dielectric properties that result from oil immersion. Data and analysis of experimental results will be presented.
