Lightning protection sheet with patterned discriminator

摘要

The present invention relates to a lightning protection sheet comprising an electrically conductive film having thickness t and an electrically non-conductive first discriminator layer having thickness T DL over the electrically conductive film, where the first discriminator layer comprises a first material having a first dielectric breakdown strength and particles of a second material having a second dielectric breakdown strength that is less than 90% of the first dielectric breakdown strength, where the average diameter of the particles is between 50% and 100% of T DL .
