Even glass-plastic hybrid connections have been used very successfully for quite a while in the field of laminated glass technology. Connecting glass sheets with relatively thick interlayers of special synthetics result in sheets which have a high breaking resistance. This construction form is limited to elements such as shop windows, security walls in buildings, doors, etc. (Business, 2003). Substantial investigations showed that there is no approach to deploy these hybrid connections – in a new quality – to create carrying elements.
When designed correctly the plastic sheets are capable of transmitting normal as well as shearing stresses, even though the e-modulus of the plastic is significantly lower than the one of glass. The glass sheets within the hybrid elements can be coupled shear proof over the plastic sheets when appropriate adhesive techniques are deployed. In doing so, one achieves cross-sections with a favourable longitudinal force and bending carrying capacity while the coupling element is not in danger of a brittle fracture like glass since it is made of ductile plastic. The transmission of shearing forces between bridge and flange occurs through the ductile plastic. (See Fig. 4)
