How planes are made?
carbon fibre is the new technology for manufacturing plane components, due to its unique weight to strength ratio, along with its unique way of manufacturing carbon fibre as the designer can place X amount of fibres in X amount of directions which can completely change the angle of strength of each component
Most planes were made of aluminium, but not all. One of the finest planes in WW2 was a fighter-bomber made entirely of wood. Powered by two Rolls-Royce 'Merlin' engines, the de Havilland "Mosquito" flew higher and faster than any other plane at the time. There were a few other wooden planes made during WW2.
