Composite materials have been used in aircraft industry for many years. There are many undisputable advantages of composite materials in comparison to metallic aircraft structures, such as better strength to weight ratio, less maintenance time during exploitation, extended aircraft service life, less structural part count, less number of fastenings, better corrosion and fatigue performance, etc. the short overview of composite materials usage in military and civilian aircraft industry is presented in this paper. the modern technology attainments in design, production and mechanical processing of composite materials are shown. New achievements in automated laying up processes, such as multy-head machines, layer markings and quality control are presented. the Resin Transfer Molding - RTM method with a gain to eliminate prepregs and huge refrigerators in composite structure production is also shown. Manufacturer endeavours to substitute expensive autoclaves with cheaper thermal ovens for resin polimerisation are highlighted. New breakthroughs in classical and orbital drilling of composite materials are presented.
