“…The aluminium is sandwiched between the carbon layers formed as fiber metal laminates (FML), and it has excellent qualities such as overall reduced weight, corrosion resistance and environment friendly. Along with the host of benefits, the main disadvantage is the fabrication of these composites which is difficult 1 . The aircraft materials are developed based on fiber metal laminates which needs the improved crack growth properties 2 .…”

Sandwich laminates play an important role in industries and they are used in varieties of engineering applications. In the present investigation, carbon fiber reinforced aluminium sandwich laminates are fabricated and their properties such as tensile, flexural and impact are studied for their use in structural applications. All the tests are carried out as per ASTM standard. Scanning Electron Microscope (SEM) analysis is carried out to investigate the structure of the sandwich laminates. The microstructures clearly indicate the fractured surface. The tested specimen clearly indicates the fracture surface of the sandwich composites.

“…Besides, Bosco et al (2015) analyzed the parameters extensively; drilling diameters, spindle speed (rpm) and feed (mm/rev) as factors, and thrust force on armor steel, thrust force on GFRP-top (N), and thrust force on GFRPbottom (N) as the responses. The design of the experiment was carried out using an L27 model, and optimization was carried out using the analysis of variance technique and the response surface regression analysis.…”

The present state of competition within the plastic composite industry calls for efficiency to be competitive. However, in the drilling of carbon-fiber-reinforced plastic (CFRP) composites, the process engineer still lacks knowledge of the priority of parameters as parameters are chosen at random, and resources are deployed without justification on their importance and strength. Consequently, production crises and productivity losses persist. In this article, the analytic hierarchy process (AHP) method is deployed to evaluate the weights of criteria in a CFRP composite drilling operation. The establishment of the decision, alternatives, and criteria is accomplished, and pairwise comparisons are conducted to allow the computation of the importance weight of each criterion. The weight is then established. The proposed approach was illustrated with experimental data from the literature with a plastic drilling case. Six criteria were chosen as crucial in determining the drilling parameters of CFRP composites. The results reveal the following: thrust force (0.413), torque (0.253), eccentricity (0.151), surface roughness (0.115), delamination at entry (0.037) and delamination at exit (0.030). In a validation exercise to ascertain the consistency of the analysis, a consistent analysis was obtained. The novelty of the article is using the AHP approach on the drilling of CFRP composites. Practically, these results impact operator training, indicating that attention should be focused on thrust force control. The industrial applications of CFRP composites include the basic structures of automobiles, ships, and airplanes.

• Delamination and surface quality in drilling of fiber reinforced polymer composites. • Effects of cutting parameters, cutting tool material and geometry on the delamination. • Effects of adhesion and abrasive wear mechanisms on the delamination and surface quality. Fiber reinforced polymer composite materials are important for aerospace industry due to their engineering properties. the delamination that occurs during cutting these materials with different cutting methods is adversely affecting engineering properties. This situation is prevalent especially in drilling operations. it has been found that stacking methods have been used in recent years and delamination has been significantly reduced. Therefore, in this study, it was aimed to transfer the findings obtained by researching the innovative studies made in the literature to the readers. Purpose: The aim of this study is to identify the findings obtained from recent studies in the literature. Theory and Methods: In this study, it is aimed to reveal the results obtained from the innovative studies carried out within the scope of the study. Results:I n the industrial applications, especially in aircraft industry, it is necessary to use the optimum cutting speed values in the stacked structures. However, in the case of stacked structures, it is necessary to use the optimum cutting speed values for each material. Ti or Al, FRP's/Ti, FRP's/Ti, FRP's/Ti and FRP's/Al/ FRP's stacked structures are used in the body and wing connections. Due to the adherence of the chips (BUE) to the machined surface and the cutting edge of the cutting tool due to adhesion, micro-level particles broken off from metal and FRP's materials due to the mechanical loads cause abrasive wear on the cutting tool. It has been determined that MQL and spray spray cooling method which can be used with PCBN or PCD tools as well as stepped or small angled point drills to minimize delamination, increase hole quality of metal and FRP's material to cause delamination in FRP's material. Conclusion: It has been determined in the literature that low cutting speeds should be used in combination with high cutting speeds in order to reduce delamination. However, in addition to the cutting parameters, cutting tool geometry, coating method, and material type also have significant impact on cutting performance. It is considered that the abrasive water jet cutting method may be advantageous for metal-stacked ETPK structures in that the drilling of the front hole can reduce the occurrence of delamination particularly in the ETPK layers stacked with metals, thereby reducing the thermal effects that may occur during cutting. In addition, the relationship between the different fiber angles and the surface damage occurring at the cutting surface is of great importance in terms of the effectiveness of the results obtained by performing different statistical modeling studies for estimating the cutting temperatures in different regions as well as delamination, burr formation, cutting force and surface roughness in st...
