Outside of aeronautics, composite materials are very fashionable, they represent everything high-tech, cutting edge and well engineered. There are carbon fibre golf clubs, bath tubs and suitcases. Within the aeronautics industry composites are also held in high regard; the path to weight savings, complex geometries and fewer parts. Yet it is also very hard to quantify exactly how beneficial composites are. They are very different to aluminium, and challenges such as impact resistance, expensive manufacturing processes and repairability lead to different design philosophies, which in turn make it difficult to compare composite and metal designs directly.
