The lifetime of aircraft is extending over the years. Up to 25 years ago aircraft are basically designed for a lifetime of around 20 years. Current designs are aiming at a life of 30 years and beyond. Furthermore, several flying aircraft models undergo a so-called end life update, extending its life to even more than 80 years. While damage tolerance was already one of the main design drivers over four decades ago, current design goals require an even more damage tolerance structure. To obtain this goal it will be essential to have a damage tolerance material. In the late seventies Delft University recognized this aspect and developed a damage tolerance material concept. This concept turned out to be a new generation of material called: Fibre Metal Laminates (FML). One grade of FML, called Glare, showed very good characteristics, which makes it suitable for several application areas on the aircraft. The characteristics of Glare dealing with damage tolerance will be discussed.
