In order to investigate the service performance of novel fiber metal laminates (NFMLs) used in aircraft skin structure

the mechanical properties of NFMLs within -55-120℃ were studied. The interlaminar performance was evaluated by the method of floating roller peeling and interlaminar shear test. The static properties were evaluated by tensile

bend and interlaminar shear tests. The yield strength of NFMLs at high and low temperature was calculated and analyzed based on the mixing theory. The results showed that the interlaminar performance of NFMLs decreased with the increase of temperature

and the tensile or bending strength had excellent high and low temperature performance

but the stiffness decreased obviously

and the change of yield strength was different from that of pure aluminum alloy. Results indicated that the mechanical properties of NFMLs maintained well within -55-70℃ but deteriorated at 120℃ .
