Objectives and work programme
KL-megla and the TU Dresden intend to develop a modular glass-stainless steel joint with transparent, linear adhesive bonding. The possible areas of application may include fall-safe glazing (balustrades), glass partition walls, atrium glazing with a fall protection function, and shower partitions. To ensure an adequate degree of impact resilience, a bonded connection offering sufficient rotation (spring plate, sandwich bond) must be developed that meets all of the structural requirements in the various areas of application. One design variant has the transparent glass-stainless steel joint formed directly with a spring plate. Under the stress of impact, the stiffer stainless steel bond can compensate for the stress by opening the spring plate. With a sandwich bond, resilience is ensured by way of a softer, elastic adhesive bond behind the visible bond (transparent glass-stainless steel joint). The stress of impact is therefore absorbed by the deformation of the elastic adhesive bond. It must be ensured that the adhesives are compatible with one another.
