“…Figure 3 proves that AGL is more impact-resistant than ACL. AGL is characterized by greater F init (respectively, 2304 N and 2787 N in average), much higher F max (by 43% for E 0 = 16 J), and significantly decreased d f (by 18% for E 0 = 16 J) than ACL, despite the greater Young's modulus of CFRP than glass fibre-reinforced polymer (GFRP) [39]. The ratio of d f to the maximal deflection of the plate (ACL-71% for E 0 = 16 J, AGL-61% for E 0 = 16 J) indicates the significant role of plastic deformation of metal while damage is developed.…”

An experimental analysis of mechanical behaviour for aluminium-based fibre metal laminates under compression after impact was conducted. Damage initiation and propagation were evaluated for critical state and force thresholds. Parametrization of laminates was done to compare their damage tolerance. Relatively low-energy impact had a marginal effect on fibre metal laminates compressive strength. Aluminium–glass laminate was more damage-resistant than one reinforced with carbon fibres (6% vs. 17% of compressive strength loss); however, aluminium–carbon laminate presented greater energy dissipation ability (around 30%). Significant damage propagation before the critical load was found (up to 100 times the initial damaged area). Damage propagation for assumed load thresholds was minor in comparison to the initial damage size. Metal plastic strain and delaminations are dominant failure modes for compression after impact.
