Laminated glass is made of alternating layers of glass and of soft, optically transparent polymers. This material is widely used in automotive and construction to contain glass shards in case of impact, but its actual resistance to impact is limited. Here we enhanced the performance of this material using bioinspired concepts. Although nature provides a few examples multilayered materials, most hard biological materials have more complex architectures including brick and mortar, cross-plies or Bouligand structures. We implemented some of these features by using laser engraving on laminated glass models made of borosilicate glass and Ethylene-vinyl acetate (EVA). While the deformation and fracture of basic laminated glass only involved a small fraction of polymers, the more complex architectured laminated glasses triggered specific and controlled deformation and fracture mechanisms that involved larger volumes of polymer. As a result, the bio-inspired architectures added to laminated glass significantly improved deformability, toughness and impact resistance.
