Extended Service Life of Transparent Armor

The focus of this Phase I proposal will be transparent armor lifetime increase through reduction or removal of residual stresses through a unique lamination technique - Radio Frequency (RF) Lamination. The residual stress of RF lamination will then be compared to autoclave lamination via cross polarized light and polarimeter measurements. JNI Armor will then integrate methods to design an efficient high-quality laminate. To validate life extension JNI Armor and Applied Physical Sciences Corp will then develop an accelerated test method focusing on high temperature and moisture. Then with support from the test capabilities of Southwest Research Institute, the team will test standard laminates and RF laminates to the accelerated test protocol. It is anticipated that combining this technology with systems to reduce moisture ingression (edge seals), and proper frame integration, lifetime can be extended beyond 6-10 years.
