“…Because the fibers have different properties in different angles, this leads to the phenomenon of anisotropy. Due to the anisotropy of fibers, FMLs also have different mechanical properties in different directions [70,74].…”

Fiber metal laminate (FML) is a kind of lightweight material with excellent mechanical properties combining advantages of metal laminates and fiber reinforced composites. It has been widely used in the aerospace and transportation fields and is especially used as structural material such as aircraft skins, wings, and tails. However, under complex service conditions, interlaminar failure in FMLs greatly reduced mechanical properties of the material, even leading to serious economic and safety disasters. The failure and destruction of important structural parts of aircraft and other manned transportation vehicles are extremely unsafe for people. Therefore, it is of great significance to summarize the interlaminar failure behavior of FMLs and find ways to avoid these defects. This review paper is a collection of various researches done by many groups, which systematically discuss the interlaminar failure behaviors and their control methods of FMLs. The application status of several common FMLs in aircraft structures was given. The common interlaminar failure modes of FMLs and the testing and evaluation methods of interlaminar properties were stated. The failure mechanisms and the corresponding control methods were analyzed. Finally, the future developments of FMLs were also discussed by the authors. Through this review article, readers can obtain new research progress about the control method, the mechanism and future development on the failure behavior of FMLs in a more efficient way.

“…where h B (¼ r b /2k 2 ) is the corner of the foundation beam at point B. Combining equations (12) to (15), it can be seen that reducing the size of cutting force can decrease the fiber deformation and cracking depth. In summary, the cutting direction from outside to inside of the body with small cutting force is an effective way to inhibit the surface damages.…”

“…CFRP as the typical hard to cut material, the tears, burrs, and delamination are often to occur on the surface of the material with weak unilateral constraint in the milling process especially. [12][13][14] Due to the damages, the bearing capability of CFRP will decrease reducing the life-span of the assemblies. It is important to note that there are serious economic losses and waste of time for repairing the damages.…”

Carbon fiber reinforced plastic/polymer is popular for aerospace structures and these structures require milling with desired configuration and integrity within strict damage tolerance. However, due to the influence of cutting thrust force on the surface materials when milling carbon fiber reinforced plastic/polymer, it is easy to cause surface damages. This article aimed to study the effect of cutting thrust force direction and size on the damages and guided the suitable milling tool and cutting parameters, further to propose a milling method with low damages. The two-dimensional cutting model was established successfully for analyzing the tool–composite contact and the fiber–plastic/polymer interface crack. Based on the model, the cutting direction forward inside and small cutting force are the ways to avoiding the burrs and tears. The thrust force was the main concentrated force causing the damages in milling, so the left–right edge milling tool was proposed to realize cutting fibers to inside for both surfaces. Besides, small feed per tooth is an effective way to reduce the force. Therefore, the left–right edge milling tool with small feed per tooth is low-damages method. Comparative milling experiments are carried out to verify the method, from the result, the burrs, tears and delamination are effectively inhibited.

Thermal loading of fiber reinforced composites during traditional machining is inevitable. This is due to the fact that most of the mechanical energy utilized in material removal is converted into heat, which is subsequently dissipated into the workpiece and the cutter, and is carried away by the chips. Heat conduction into the workpiece during machining might cause thermal damage due to matrix softening and decomposition if the generated temperatures exceeded the glass transition temperature of the epoxy resin. In this work, the amount of heat flux applied to the machined edge and the temperature distribution in multidirectional CFRP and GFRP composite laminates was determined using an iterative inverse heat conduction method. The transient heat conduction problems in the laminate and cutter were simulated independently using the finite element method and the amount of heat flux applied to each was determined. It was also found that the heat flux conducted to the workpiece represented only a small fraction of the total heat and is more influenced by the feed speed than the spindle speed. The temperature of the machined surface was estimated and correlations with the resulting machined surface texture were made.
