In this contribution, we examine the mechanical behavior of laminated glass fabricated with relatively thin (<2 mm) glass components. It is shown that optimum light weight laminates are best achieved through the use of a relatively stiff, ionomer interlayer versus a traditional rubbery, poly-vinyl butyral (PVB) interlayer. We present results of bending experiments in which laminate deflection and glass stress development have been monitored as a function of load for various laminate structures. Interpretation of laminate mechanics using effective thickness theories is demonstrated. We present a formulation for computing the optimum specific stiffness and strength of a laminate for given loading/support conditions and establish theoretical limits to weight reduction for a defined monolithic glass performance target.
