During more than 10 years of working with complex laminated assembly, we were often asked to replace failed components, or find an explanation for a collapse. We always try to understand the root causes of those events and come up with experiments to validate our hypothesis.

Engineers use multi-layers laminates to increase strength, redundancy and residual capacity but some configurations are not necessarily safer and can lead to catastrophic failures.

Since the original Apple staircase, metallic components embedded in glass laminates have been used more and more. We will show why some metals can be dangerous.

In previous GPDs we introduced our work on optical phenomena that happen with rigid interlayers. We will do a quick review of our work on anisotropy that paved the way to two new standards to quantify it in architectural glass. We also want to show what is happening on haze control with the introduction of a new generation of ionomers.
