Abstract: A system may have structure. The structures may include laminated structures formed by attaching inner and outer layers together with a layer of adhesive. The inner and outer layers in a structure may be formed from polymer such as polycarbonate. Forming the structure layers from polymer may allow the structure to have desired curvature. To improve safety and/or acoustic performance of the structure, the inner and outer structure layers may be formed from different materials. The outer polymer layer may be formed from polycarbonate and the inner polymer layer may be formed from a more brittle polymer such as polymethyl methacrylate (PMMA).
