In recent years the big emphasize in making the aircraft construction is put on a composite materials. The use of newest polymer composite in airplane industry are discribed in this final paper. Furthermore, the composite materials are introduced and explained. Different types, method of manufacture and application is explained more closely with the particular emphasis on polymer composites reinforced with fibers. The composite materials in airplane industry can be used in many ways and in many different combinations. Each type has its own advantages and features that compete with the conventional materials. In making the structural elements of the aircraft composite materials enable the production of complex structures and forms which in a same time allows very high performance of the new materials. Because of these advanced properties of hybrid composite materials the development and production of the aircraft high performance is possible. The main features that are improved are decreased weight of the aircraft , therefore they has better safety of the aircraft. Future manufacturing technology of composite materials with standardization provides automated processes that reduces the cost of building an aircraft composite structures.In this final paper the application of composite materials on aircraft Boeing 787 Dreamliner, Airbus A380 and Pipistrel Panthera is closely explained.
