Aerospace applications of non-crimp fabric composites

Abstract: This chapter reviews the specific requirements, successful applications and future trends of non-crimp fabric (NCF) composites in the aeronautic sector. Starting from a state-of-the-art overview of composite primary structures, key issues explaining the low usage of NCF today are reflected on, with a focus on the generally inferior damage tolerance performance of resin-infusion-based composites when compared with tough prepreg (pre-impregnated) systems. However, there are at least two major success stories for NCF composites in recent aircraft programmes: the Airbus A380 rear pressure bulkhead and the A400M cargo door. Looking ahead to the challenges of the next generation of composite aeronautic structures, it seems likely that this list will be extended in the near future.
