Summary of the Evaluation of PPG Herculite XP Glass in Punched Window and Storefront Assemblies.

摘要

Protection Engineering Consultants (PEC) was engaged by AFRL to evaluate the performance of Herculite. XP glass used in standard commercial window configurations and frames for force protection applications. Herculite. XP is a high-strength glass technology with a residual stress about twice that of commercially produced fully tempered glass. The research program included quasi-static tests of Herculite. XP glass at PEC and shock tube tests of punched windows (Herculite. XP insulating glass units (IGUs) with commercial window frames) at ABS Consulting, on Herculite. XP IGUs in punched window and storefront configurations using commercially available window frames. The main goals of this research program were to evaluate the performance of Herculite XP window systems, confirm parameters for use in fast running design tools, and develop a robust and conservative design method for specifying Herculite XP. The SDOF analysis tool conservatively predicted the performance of Herculite. XP IGUs in standard layups subjected to dynamic loads. In general, Herculite. XP can provide the same level of protection as annealed (AN), heat strengthened (HS), or FT glass using a thinner and lighter section. A design method was also outlined to incorporate Herculite. XP glass into existing industry standards, such as ASTM E1300.
