Julian Hänig | Load Bearing Behaviour of Innovative Lightweight Glass-Plastic-Composite Panels

Session: Thin Glass & Applications Event: GPD Finland 2019 Load-bearing behaviour of Innovative Lightweight Glass-Plastic-Composite Panels The trend towards large glass façades and the urge to reduce the material to a minimum requires further development in high-performance lightweight structures. Therefore, a combination of plastic interlayer core and cover layers of thin glass was developed to reduce self-weight and utilize the high durability of glass at the same time. The glass-plastic-composite panels behave as a unit and ensure a safe load-bearing behaviour. First studies including four-point bending tests according to DIN EN 1288-3 showed a nearly equivalent load-bearing behaviour to monolithic glass panes with the same nominal thickness. However, the composite behaviour significantly depends on the time and temperature-dependent stiffness of the plastic interlayer material as well as the shear connection between core and glass. Hence, an extended experimental study on the time and temperature-dependent load-bearing behaviour of the new composite panels was performed. The paper presents and discusses the insights. Additionally, it includes a study on potential material models and numeric simulations to extend the results to a large scale of application. The simulations correspond to experimental results and allow a suitable design of the new high-performance glass-plastic-composite panels.
