Static and dynamic characteristics of nano-reinforced 3D-fiber metal laminates using non-destructive techniques

Abstract

Uncontrolled vibration in mechanical systems (e.g. aircraft, trains, and automobiles) may result in undesirable noise and eventually, cause mechanical failure. In this context, the main objective of the present research is to explore parameters that govern and affect the frequency response of three-dimensional fiber metal laminates. Three-dimensional fiber metal laminates are a class of novel lightweight hybrid material systems with great potential for use in aforementioned applications. Therefore, the vibration characteristics of the two most commonly used configurations of three-dimensional fiber metal laminates are experimentally investigated by nontraditional and conventional approaches. Material damping is also improved by the inclusion of two different types of nanocarbon particles within the core and/or interfaces of the hybrid system. The results are presented and compared. The inclusion of nanocarbon particle improved the fundamental frequency of the system slightly; however, material damping was enhanced significantly when only 1 wt% nanocarbon particle was used in the interfacial sections of the system.

Recent trend in developing advanced fiber metal laminates reinforced with nanoparticles: A review study

“…Up to now, many researchers have investigated the effects of various parameters, conditions and properties of different FML structures. Using the shape memory alloys [99], fabricating the FMLs with the 3 D fiber-reinforced composites as the core [100], designing the FMLs for using the hygrothermal and cryogenic conditions [101], substituting the synthetic fibers with natural fibers in the FMLs [102], and using the new methods for characterization of features of FMLs like acoustic emission [103] had a remarkable growing rate in the past years. On the other hand, the developing and fabricating the materials with new features like self-healing structures [104,105] and shape memory effect [106] are the interesting subjects for different researchers and industries.…”

Enhancing Mode-I and Mode-II fracture toughness of carbon fiber/epoxy laminated composites using 3D-printed polyamide interlayers

“…Furthermore, external influences such as out-of-plane loading, eccentric or cyclic loading paths, and low-velocity impacts experienced during the service life of a composite laminate can significantly expedite the propagation of delamination. [6][7][8][9][10][11] One important measure of a material's ability to resist delamination is its Mode-I fracture toughness. Unfortunately, carbon fiber/epoxy (CF/EP) composites typically exhibit Mode-I fracture toughness values ranging from 0.2 to 0.4 kJ/m 2 , 12,13 considerably lower than the fracture toughness observed in high-strength steels, which can reach as high as 290 kJ/m 2 .…”

Mechanical performance of a novel environmentally friendly basalt‐elium® thermoplastic composite and its stainless steel‐based fiber metal laminate

“…It should be noted that one of the major focuses of research in our group in the past 7 years has been the characterization of the mechanical response of a novel group of FMLs under static and dynamic loading conditions. [24,[26][27][28][29][30][31][32] Therefore, the second objective is to investigate the mechanical properties of a new class of cost-effective and environmentally friendly FML that could be fabricated by the aforementioned fiber and resin constituents combined with stainless steel (SS) sheets. Finally, the last objective of the present investigation is to determine the influence of two different fabrication processes on the mechanical properties of the TP-FML.…”
