“…The same process was repeated until the whole stack sequence was done. Finally, a flat surface (glass sheet coated with paraffin wax) was placed over the laminates [17,19]. Weights of 45 kg were placed over the laminates for 24 hours at room temperature for curing.…”

“…Xie et al [17] investigated the impact due to notch geometrical properties such as notch shape, notch size, besides off-axis angle on the tension testing of GLARE composite laminate with circular notches in addition to square notches. Also, they discovered that the strength of the square notched laminate is roughly equivalent to that of the circumscribed circle notch laminate.…”

Glass laminate aluminum reinforced epoxy (GLARE) mixes a layer of aluminum with fiber-reinforced epoxy to constitute a hybrid composite. During this investigation, plain E-glass fiber/epoxy specimen in addition to hybrid composite laminated epoxy specimens reinforced with both E-glass fiber and wire meshes of aluminum were produced. Tensile, bending, and hardness tests were performed to investigate how inserting Al wire meshes through thickness of the specimen in place of glass fiber layers affected the material mechanical characteristics. The characteristics of the generated hybrid laminates represented by strength and ductility were greatly influenced by varying the position and orienting direction of the aluminum wire mesh ply. Inclusion of Al wire mesh in the outer layers significantly causes deterioration in material tensile and bending strengths. The tensile strain as well as bending strain, on the other hand, were improved as a result of incorporating Al wire meshes by 51.3 percent and 153.4 percent, respectively.

“…e stability of GLAREs is a common concern, and the situation becomes even more critical when there is initial damage [28][29][30]. Up to the present time, countless research has already been devoted to specifying the compression buckling of FMLs [31][32][33][34][35][36][37][38][39][40].…”

GLAREs as hybrid materials are widely employed members of fibre metal laminates (FMLs) in aerospace structures. Delamination is one of the most critical failure modes that happen during the manufacturing or service life, decreasing the stability and reliability of the GLARE laminates. Accordingly, this study presents an investigation of the shear buckling phenomenon, a very common load condition in aerospace structures, of different GLAREs, differentiating in the laminate layout, containing embedded delamination by the FEM ABAQUS software. The cohesive zone interface elements of FM94 are considered to evaluate the delamination growth. This parametric study displays the effect of the initial delamination dimension and its position as well as the thickness of the metal layer on the stability of GLARE laminates. The model predicts the stability reduction of GLARE laminates as a function of the delamination radius and its position. The results show that aluminium layer reinforcement increases the overall stiffness and shear buckling capacity and the specimen’s resistance to delamination growth. In addition, the produced results in this study can encourage designers to select appropriate GLARE grades based on the intended application, such as different shear loading conditions and available raw materials.

“…A mixed damage criterion, including ductile damage, progressive damage in terms of strain, and cohesive model, was employed for different parent materials to study the failure of fiber metal laminates [11,12]. The effects of open-hole geometry characteristics [13][14][15] and fiber stacking [16,17] on mechanical behavior of fiber metal laminates with open-hole were discussed based on a modified point stress criterion, considering the interface bonding layers and isotropic hardening behavior of aluminum layers. The off-axis dependence of tensile response of fiber metal laminates under off-axis tensile loading, finding out that the critical failure is still tension-dominated as that in the on-axis case [17,18].…”

Fiber metal laminates (FMLs) are typical multilayer composites including metallic foils and fiber reinforced polymers. These are considered as the attractive skin materials for lightweight vehicle, especially GLARE laminates for aircraft fuselages. The open-hole tensile behavior and progressive damage of GLARE laminate are studied experimentally and numerically. A combined progressive failure model with strain-based damage evolution laws are imposed on the composite layer based on the subroutine Abaqus-VUMAT. The cohesive zone model and equivalent plastic strain criterion with isotropic hardening is respectively employed to describe the interlaminar and metal layer damage. The effects on the geometry characteristics of open-hole are discussed, exploring the variation of residual strength, damage evolution process and damage affected zone. The two fracture modes and delamination failure are observed, all numerical results show good agreement with experiment obtained. The damage evolution of fiber both gradually vary from "butterfly" to "funnel" pattern for circluar and square open-hole. However, the different evolution emerges for matrix damage. Compared with circular one, the square open-hole can lead to more fiber damage than matrix one. The transition fillet can effectively disperse stress concentration, improving the residual strength of GLARE with square open-hole. The 45° off-axis is the optimal design of square open-hole to fully activate the reinforcement effect of fiber. All suggest the open-hole design is important to guarantee the application security for GLARE plate-like structure.
