Abstract/Summary Bonded composite scarf repairs are often used when a flush surface is required for aerodynamic or stealth reasons. Such repairs on the external surface of an aircraft are subject to the same impact risk as that of the parent structure. Consequently, it is essential to assess their durability in the case of impact. A previous preliminary experimental study found an instance of catastrophic failure of a composite scarf joint subject to impact whilst prestrained to 3000 μ. It was postulated that this phenomenon is a result of failure in the joint due to the combination of the prestrain and global structural oscillations resulting from the impact event. In this investigation, a previously applied finite element model is extended to more accurately replicate such catastrophic failure. The effect of lay-up sequence on adhesive failure is studied.
