Low-velocity impact response of fiberglass/magnesium FMLs with a new 3D fiberglass fabric

Effect of adhesive quantity on failure behavior and mechanical properties of fiber metal laminates based on the aluminum–lithium alloy

“…Fiber Metal Laminates (FMLs) combine the outstanding fatigue resistance and high strength of fiber reinforced composites with the ductility of metal alloys [1,2]. As the second generation of FMLs, Glare is composed of alternating layers of 2024 aluminum alloy and glass fiber reinforced epoxy [3,4].…”

High-velocity impact deformation and perforation of fibre metal laminates

“…The FMLs manufactured from composite layers with unidirectional fibres gave a higher perforation resistance than the FMLs with woven fibres in the composite layers [14]. The effect of changing the constituent material on the low-velocity impact performance of FMLs was investigated by Asaee et al [24]. A magnesium alloy was used for the metal layers and a filled polyurethane foam matrix containing glass fibres was employed for the composite layers.…”

Mode I and Mode II interlaminar fracture toughness of CFRP/magnesium alloys hybrid laminates

“…However, for the FMLs tested in this work, the value of the ratio G IC /G IIC is about 0.039, which is at least one order of magnitude lower than that of the FMLs presented in Refs. [7] and [11]. It could be mainly attributed to the state of the bonding interface between metal layers and composites layers.…”

“…[4,5] In recent years, a new generation of FMLs based on magnesium alloy (Mg-FMLs) was developed to further reduce the FMLs material weight. [6][7][8][9][10][11] Pärnänen [6] and Múgica [7] demonstrated that the density of the FMLs can be reduced by around 20% when replacing the aluminum alloys with magnesium alloys. In addition, our previous work also showed that the Mg-FML with carbon fiber reinforced polymer (CFRP) as the composite materials layers have a low density of about 1.64 g/cm 3 , together with a high tensile strength (810 MPa) and modulus (82 GPa).…”
