“…is has seriously affected the service performance of FMLs as various structural parts. erefore, it is very important to analyze and study the interlaminar failure mechanism of the FMLs [46,84,[107][108][109][110][111]. e main damage failure mode of composites is interlaminar failure, which refers to the separation between the fibers and the adjacent metal layers.…”

“…It was found that both the failure mode and interlaminar shear strength depended on the number of thermal shock cycles. Under the influence of cyclic temperature changes in the test samples, the observed reduction in the strength of the layer subjected to thermal shocks is mainly caused by significantly different values of thermal expansion of the composite materials [46]. Due to the complicated loading conditions of impact and fatigue failure, the current research in this area mainly focuses on the dynamic response research under low-velocity impact [12,110,128,129], but there are few detailed simulation models for analysis, and there are few studies on the impact of high-velocity impact on material properties [24,85].…”

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.

“…One of the variants of describing the relationships characterizing damage accumulation or fatigue summation [3, 20,25,27,38,42] are phenomenological hypotheses of fatigue damage accumulation [31,32,35] and Markov network [5,13,41]. However, this is not a new idea [21].…”

The following work describes the application of a mathematical model based on Markov chain theory (MM) to estimate the fiber composite strength parameters, taking into account the laminate forming aspects using the vacuum bag method. This provides, from a unified position, a tool for a coordinated description of static strength and fatigue life. It was shown that the MM model gives relatively good results.

“…Therefore, it is of great importance to verify the surface free energy after brushing in order to decide whether brushing technology is necessary. The preparation of the surface layer of adhered substrates is absolutely critical, particularly in a situation when the bonded assemblies are expected to perform well under variable temperature cycle loading [28,29,30,31].…”

Measurements of Forces and Selected Surface Layer Properties of AW-7075 Aluminum Alloy Used in the Aviation Industry after Abrasive Machining

Measurements of forces during machining, especially thin-walled structures typical of the aviation industry, are important in the aspect of instability caused by vibration. One of the last stages of manufacturing by machining is the finishing treatment and deburring of the product’s edges. Brushes with ceramic fibres are often employed in deburring, especially for large-sized elements specific to the aviation industry due to the possibility of automatic machining directly on machining centres. This study set out to analyse the effect of variable brushing conditions on axial forces and the selected surface layer properties of AW-7075 aluminium alloy. Experimental studies have examined factors such as surface roughness and topography, axial cutting force in ceramic brush treatment and surface free energy in the aspect of adhesive joints. The tested variable process parameters were the fibre material and the adjustment sleeve spring stiffness. Based on the tests, it was found that the axial force applied by the brush was more strongly connected with the spring stiffness rather than the type of bristle. For most cases, an increase in the value of free surface energy after brushing was observed compared to the initial machining which was milling.
