Abstract : The last fifteen years have been marked by considerable changes in aeronautical materials. One of the main areas of change has been a notable lightening of the structures employed in aircraft design, thereby increasing specific thrust, of principal concern in military aeronautics, for both aircraft and helicopters. Reduction in weight has been achieved in a number of ways; mainly through the increasing use of polymer matrix composites, from the initial small-scale applications involving mechanical parts with a low critical value to the more extensive applications in wings, as demonstrated with current designs for combat aircraft. Within the last few years, in response to the development of the polymer matrix materials, the amin producers of aluminium alloys have once again taken up the development of aluminium-lithium alloys in order to exploit their advantages of low density and high elastic modulus. In fact, these alloys had been known about for some thirty years but major investment was required for their development, especially in production technology. Nato furnished.
