Abstract:
Scratch and damage resistant laminated glass articles are disclosed. According to one aspect, a laminated glass article may include a glass core layer formed from core glass composition and includes a core glass elastic modulus EC and at least one glass clad layer fused directly to the glass core layer. The at least one glass clad layer may be formed from an ion exchangeable clad glass composition different than the core glass composition and includes a clad glass elastic modulus ECL. The laminated glass article may have a total thickness T and the at least one glass clad layer may have a thickness TCL that is greater than or equal to 30% of the total thickness T. EC may be at least 5% greater than ECL.
