Description
[0001] This application claims the benefit of the filing date of U.S. Provisional Application Ser. No. 60 / 975,661 filed Sep. 27, 2007.
[0002] Commercially available, glass-based transparent armor typically consists of multiple glass and polymer layers, which are laminated together to form a relatively thick composite. The resulting composite must be transparent and essentially free of optical distortion while providing maximum protection against ballistic impact of projectiles and fragments at minimum weight and minimum cost. Of particular interest are transparent laminates, which restrict the destruction caused by the projectile locally to ensure maximum residual vision and provide protection against multiple hits.
[0003] To successfully stop a projectile, impact resistant transparent laminates typically engage various defeat mechanisms, including projectile fragmentation and mass removal by projectile erosion. Systems employing transparent ceramic materials such as, for example, transp...
