In recent years, many airplane manufacturers have started building their planes from advanced composite materials, which consist of high-strength fibres, such as carbon or glass, embedded in a plastic or metal matrix. Such materials are stronger and more lightweight than aluminium, but they are also more difficult to inspect for damage, because their surfaces usually don't reveal underlying problems...
