Energy absorption in glass-polycarbonate laminates
Last modified: 2013-02-10
Abstract
Recently advanced laminated glass structures have been developed that aredesigned for structural use. These advanced laminates fail progressively,losing some of their stiffness in exchange for a quasi-plastic deformationand thus have a failure behaviour comparable to metals and thermoplasticpolymers in that they yield before failing. Beam specimens of severaldifferent types of configuration have been manufactured and tested inbending. It is shown that the configuration has a significant effect on theenergy absorption. In certain configurations near metallic ductility andfailure behaviour is possible while maintaining the transparency of glass.The relevancy of the results for the design of transparent laminate systemsare discussed
