“…GLAREs also showed high impact resistance, fatigue strength, superior corrosion, and fire resistance. [15][16][17][18] A unique possibility to enhance the overall characteristics of a sandwich material is accomplished through blending nanofillers in polymer while preparing the FRP plies. The blends of nanofillers enhances the specific physical properties of polymer.…”

This research work is focused on development of epoxy based fiber metal laminate (FML) that comprised of multi-walled carbon nano-tube (MWCNT), glass fiber, and aluminum metal sheet. The hand layup technique was employed to fabricate the sandwich FML with different weight percentages (3, 4, and 5 wt%.) of MWCNT. The mechanical properties of the developed FMLs were determined through tensile, flexural, lap shear, and hardness tests following ASTM and IS standards. The scanning electron microscope (SEM) was used to characterize the failure mechanism of composites. The FML with MWCNT offered superior tensile and shear properties up to the addition of 4 wt%. The MWCNTs were found to be agglomerated in the epoxy when added more than 4 wt%. The FML's showed larger deformation before complete failure in shear mode with respect to the addition of MWCNTs. However, there was no considerable improvement recorded in the flexural and impact behavior of the FML composition. The addition of MWCNT fillers in the epoxy turned it more brittle and exhibited comparatively less deformation before failure in flexural mode.

“…They estimated the fiber volume fraction and void content of all the processed laminates $49% and $1.1%, respectively. Dariushi et al 30 investigated the effects of different parameters such as the number of layers, the type of fiber, and the presence of holes in metal layers on the time and quality of FMLs manufactured by VIP. The results showed that, increasing the number of fibrous layers, metal sheets or using woven fibers increased the infusion time, and the presence of holes in aluminum layers or using Continuous Filament Mat (CFM) fibers reduced the infusion time.…”

The vacuum infusion process can be used to fabricate fiber metal laminates with reduced manufacturing time and cost. In this method, the holes in the aluminum layers are created due to the better flow of the resin and to ensure that the fibers are completely impregnated. Created holes can cause problems in using these fiber metal laminates. For example, structural strength is reduced and some parts of the composite layers are exposed to environmental conditions. A proper solution to these problems has been proposed and investigated in this article. If a non-perforated aluminum layer is used as the first layer to be in contact with the mold, this layer becomes the outer layer of the structure made of fiber metal laminates. This non-symmetric fiber metal laminate will still be resistant to moisture and other environmental conditions due to the presence of an intact aluminum layer on the outermost layer, such as conventional fiber metal laminates. This aluminum layer also increases the strength of fiber metal laminates in comparison with fiber metal laminates that its all aluminum layers are perforated. In this paper, the effect of holes diameter of aluminum layers on the resin flow rate (consequently the duration of the fabrication) and the mechanical strength of the structure were investigated. The results showed that holes in the upper and middle layers of aluminum can significantly increase the speed of fabrication, but the presence of the holes causes a slight decrease in the final strength of the sample.

“…[ 6,7 ] Therefore, the quality of the holes and the effect of the drilling process on the constituent materials become of paramount relevance, not only in terms of the potential economic losses due to the rejection or the reworking from out of tolerance or poor‐quality holes, but also in terms of the reduced reliability and safety of the structure due to weaken strength. [ 8,9 ] However, drilling of layered structure made of dissimilar materials with the scope of obtaining high quality holes, having tight tolerances and no or limited defects, can be challenging due to the different machinability of the two constituents inside the FML. [ 10–12 ] While the drilling of metal laminates is well known and optimized, even for hard‐to‐machine alloys, such as titanium‐based ones, [ 13 ] the issues arise in the machining of carbon/glass composite.…”

Drilling process of fiber metal laminates (FML) requires a proper design of the processing parameters to prevent the occurrence of several issues and minimize defects, which can be detrimental for the integrity of the parts. These aspects become more critical in dry machining used in aeronautic field. In this scenario, the monitoring of process temperature is crucial to obtain useful information for machining optimization since many critical factors, such as matrix burnout, fiber pull‐out and delamination, depend on the heat generated during the machining. The aim of this work is to monitor the temperature measured on the tool and workpiece during dry drilling of Al/GFRP (GLARE) and Al/CFRP (CARALL) hybrid laminates. The influence of the cutting speed on the temperature trends was analyzed. Two different set‐ups were designed to measure the temperature on the tool, near the cutting edge and on the flank, and inside the laminate, in both the metallic and the composite parts. In addition, a numerical model to analyze the process temperature trend during drilling has been developed. The increasing the spindle speed from 1500 to 8000 rpm resulted in a decreasing of maximum temperatures of approximately 10°C on the tool tip and on the flank for the GLARE, and of almost 20°C in the CARALL laminates. The numerical simulation also pointed that the temperature fields is dictated by the thermal properties of carbon and glass fibers: temperature profiles within the CARALL were found smoother than those observed in GLARE.
