Fiber　metal　laminates　(FMLs)　are　hybrid　composite　materials　exhibiting　extensive　potential　for　application　in　protective　structures　due　to　their　excellent　impact　resistance.　In　this　study,　the　ballistic　performance　of　glass　fiber　reinforced　aluminum　laminate　(GLARE)　impacted　by　different　nosed　projectiles　was　investigated　experimentally.　The　ballistic　tests　were　conducted　based　on　one-stage　gas　gun　with　high-speed　camera　system.　Microscopic　X-ray　computed　tomography　(mu　CT)　scan　was　utilized　for　internal　damage,　delamination　and　failure　detection　of　the　GLARE　plates　after　ballistic　tests.　The　experimental　results　show　that　the　ballistic　limit　of　GLARE　impacted　by　a　flat　nosed　projectile　is　higher　than　in　the　case　of　a　conical　or　spherical　nosed　projectile.　The　dominated　failure　mechanism　of　the　GLARE　plate　impacted　by　flat　nosed　projectile　is　shear　failure　at　the　impact　side　changing　to　tensile　failure　at　the　rear　side.　For　plates　impacted　by　conical　and　spherical　nosed　projectiles,　the　typical　tensile　tear　failure　with　petal-shaped　holes　was　observed.　This　study　provides　an　in-depth　understanding　on　the　impact　response　of　FMLs,　promoting　the　application　of　GLARE　in　the　field　of　military　equipment　and　aerospace　engineering.
