Thin glass in façades
Adhesive joints for thin glass composite panels with 3‐D printed polymer cores

Thin glass is a popular display material for smartphones and tablets. However, it is also suitable for new types of glass applications in the building industry. Due to its high strength and low thickness (0.1-2 mm), thin glass is very flexible, light and easy to bend, making it an attractive material for facade applications. However, thin glass cannot simply replace conventional facade glazing. To avoid excessive deformation of the glazing due to its high flexibility, it must be stiffened.

A promising idea is to use sandwich elements consisting of two thin sheets of glass with an inner polymer core. In order to retain the advantage of the low weight of such thin glass façade elements, 3D-printed polymer structures should be used instead of a solid polymer core.

The present study is dedicated to the investigation of suitable adhesives for the adhesive bonding of the 3-D printed polymer structure to the thin glass. The mechanical and thermomechanical properties of different combinations of typical 3D-printable polymers and transparent adhesives were analyzed and evaluated with respect to temperature and UV exposure in the facade.
