Experimental and Numerical Approaches on Behavior of GLARE 5 Beams: Influences of Thickness and Stacking Sequence

A Review on Mechanical Properties and Response of Fibre Metal Laminate under Impact Loading (Experiment)

“…The type of reinforcement and fibre orientation/stacking sequence of fibre ply affected the impact performance of the FML structure 33,38,63,65) . Impact resistance of FMLs can be affected by metal arrangement in FML structure 38,52,53,64) but not significantly affected by the thickness of composite laminate 31,55) . However, increasing the thickness of the FML structure or the number of layers in the FML structure increased the impact resistance and energy absorption of FML 39,50,59,64) .…”

“…Impact resistance of FMLs can be affected by metal arrangement in FML structure 38,52,53,64) but not significantly affected by the thickness of composite laminate 31,55) . However, increasing the thickness of the FML structure or the number of layers in the FML structure increased the impact resistance and energy absorption of FML 39,50,59,64) . Then, less deformation would occur in FML compared to composite laminate due to the reinforcement provided by Al sheet 39,52) .…”

“…Yaghoubi and Liaw 64) conducted a ballistic impact test on the GLARE 5 beam by varying the thickness (layup configuration from (2/1) to (6/5)) and stacking sequence (cross-ply…”

“…The better impact response of FML compared to the Al was attributable to energy-absorbing mechanisms including plastic deformation in the thin Al plies and matrix cracking and fibre fracture in the composite layers 66) . In conclusion, FMLs were subjected to various impact loading including LVI 39,[50][51][52][53][54][55][56][57]59) , HVI 66) , quasi-static impact 63) , ballistic impact 64) , Charpy impact 33) and Izod impact 16,51) tests. The FMLs had superior impact properties compared to composite and metal alloys (which act as baseline material) 60) .…”
