Advantages of applying composite material to replace metal alloys in aviation

Composite materials were already used by man in the early agricultural societies and the expanding use of this material has been driven by technological needs of the military. The high fuel prices and increasingly stringent environmental laws have created a great demand for use of this technology in the civilian sector. The purpose of this article is to show the application advantages of composites in aircraft structures, particularly in reducing weight, reduce operating costs, environmental, social and economic impact. The materials and methods were document and experimental research available in a number of studies and publications, as well as comparisons with similar aircraft composite alloy material and finally the influences in the global economy, with the reduction of freight costs in air transportation and the effects on the whole production chain which is significantly improved.
