Abstract
A laminated glazing unit composed of an improved polymer interlayer composite interposed between two glass sheets and its method of manufacture are disclosed. The improved interlayer contains various layers with appropriate thicknesses of silane primer, poly(ethylene vinyl acetate) and poly(ethylene terephthalate) arranged and bonded together in a particular fashion to increase the fragment retention capabilities of the laminated glazing while also improving the overall penetration resistance and safety characteristics of the structure without increasing the rigidity to a point where it poses a safety threat to the occupant.
