What is windshield delamination?

Windshield delamination refers to the separation of the layers or plies that make up the windshield. This phenomenon can occur due to factors such as exposure to extreme temperatures, moisture ingress, or prolonged UV exposure, which can weaken the adhesive bond between the layers. When delamination happens, it compromises the structural integrity of the windshield, leading to potential visibility issues and the risk of water leaks into the aircraft. Identifying and addressing delamination early is essential in maintaining safety and performance standards in aviation.
