FIRE DANGER, POSSIBLE METHODS OF ASSESSMENT AND REQUIREMENTS TO POLYMERIC MATERIALS FOR MANUFACTURING OF EXTERNAL CIRCUIT OF AVIATION TECHNICS
According to manufacturing of transport aircrafts having high profitability and passengers capacity and increases of fire safety of aviation engineering, in world practice expansion of use of polymers as constructional materials are carried out. Questions of fire safety change for aviation engineering are considered in this article at replacement of external circuit from aluminum alloys coverings on coverings made from polymeric composite materials. Methods of assessment of fire safety for the constructional materials being on exterior surface of product and subject to influence of flame from fire of spread fuel are analyzed. It was shown that currently polymeric composite materials yet do not provide essential increase of fire safety: increase of resistance to through burn-out is leveled by ability to extend flame on surface.
