    In this study, newly developed fibre-metal laminates (Al-LiFMLs) were prepared by a lay-up process of a high-performance surface-modified glass fibres/phthalonitrile (GFs/PN) composite and Al-Li alloy. The results showed that varying the composite considerably affected the tensile properties of the Al-LiFMLs, as well as exhibiting enhancements over the properties of both the individual Al-Li alloys and GFs/PN composite constituents. For instance, when the number of composite layers varied from 6 to 14, the ultimate tensile strength of the Al-LiFMLs increased from 315 to 611 MPa. It was revealed that the failure mode displayed a more ductile behaviour (up to 20%) for all the developed Al-LiFMLs affected by the ductile fracture mode of the Al-Li alloy.[GRAPHICS]
