Interestingly, no matter how large a monolithic ALON® window Surmet makes, there are always customers who want windows of even larger sizes! To meet these needs, Surmet has developed approaches to produce very large armor windows using tiling approaches.
ALON® Armor typically consists of an outer ALON strike face laminated to layers of glass and polycarbonate. Since the glass and polycarbonate sheets are available in very large sizes, this construction allows ALON® armor windows to be assembled by assembling and laminating multiple ALON tiles of smaller size on the surface of monolithic layers of glass and polycarbonate.
As shown in the picture, the seams between ALON tiles can be engineered to maximize the ballistic performance with minimal optical obscuration. With appropriate seam design, tiling provides multi-hit ballistic performance and producibility over monolithic windows. Tiled ALON® Armor windows have been very successfully used to defeat 30 cal and 50 cal AP threats even when shot directly at the seam locations, as well as to defeat IED threats.
This same tiling approach is used in opaque ceramic armor systems, where tiling allows the damage to be isolated to one ceramic tile, thus enhancing multi-hit performance of the armor.
Since smaller tiles can be produced in higher volumes, with higher yields, at lower cost per unit area, tiling provides significant cost advantages over large monolithic windows.
