Abstract
Various embodiments for a laminate glass article and related methods are provided. The laminated glass article includes a first and second glass layers with an interlayer positioned therebetween, comprising: a polymer core layer comprising a high modulus polymer (e.g. polyethylene terephthalate, polycarbonate, polyacrylate, and polyimide); a first low modulus material layer (e.g. first TPU or first PVB or first EVA) configured between the first layer and the polymer core layer; and a second low modulus material layer (e.g. second TPU or second PVB or second EVA) configured between the second layer and the polymer core layer.
