The improvement in the comprehensive performance of military bridges could not be achieved without the application of new materials.Fiber-reinforced aluminum laminates are now widely used in the aerospace industry.It is not only light in weight and high in strength,but also has the advantages of being good in impact resistance and fatigue strength,and being easy to process,all of which make it better than traditional FRP in comprehensive performance.According to the present application of fiber reinforced aluminum laminates to the manufacture of aircraft,the application advantages of the material in improving the impact resistance and the fatigue-enduring performance of military bridges and decreasing the manufacturing cost of the mem-bers of military bridges are analyzed,with some of the important problems in its application put forward,the solution of which has to be focused on.Those problems include the right choice of the structural form of the military bridge,the structural stiff-ness and the longitudinal connections between two bridge bays.
