UAV and composite material

Back in 1948, aircraft were made primarily of metal alloys, which were extremely heavy, noisy, corrosive and required extensive amounts of maintenance making them less efficient than modern solutions for flight. The aerospace industry has steadily been adopting composite materials into their designs to achieve lighter solutions with the same strength of metal alloy counterparts yet with many added benefits such as corrosion resistance, lower required maintenance, advanced sound attenuation (noise reduction), greater design freedom and longer life spans. Since 1987, the use of composites in the aerospace industry has doubled every five years to the point now where many newer aircraft are made with more than 50% composite materials, such as the A350 XWB and the Boeing 777X. carbon fabric,carbon plates ,honeycombed plates are lightweight ,anti erosion,sound isolation  are ieal material for bulkhead of modern aviation industry
