“…The charpy impact test was performed as per ASTM A370, using typical subsize dimensions of 55 mm long, 10 mm wide, and a v-notch in the middle of the specimen. Free vibrational analysis for FML was determined in a cantilever beam condition [39,40] with specimen dimensions of 250 mm length Â 25 mm width Â 3 mm thickness as per ASTM E756. A span length of 224 mm and clamped length of 23 mm was taken for testing.…”

Fiber metal laminates (FMLs) are a hybrid composite material used in aircraft structural parts. They are fabricated by stacking thin aluminum sheets with a fiber-reinforced polymer composite. In this research work, nanosilica was mixed with epoxy resin in different weight percentages such as 0, 1, 3, 5, and 7 wt% for the preparation of FML. Nanosilica was used as a secondary reinforcement in the epoxy resin to improve the interfacial bonding and mechanical strength of the FML. The morphology and chemical compositions of the cured nanosilicadispersed epoxy resin and aluminum were examined using Fourier transform infrared spectroscopy, X-ray diffraction, field-emission scanning electron microscope, and energy-dispersive X-ray analysis. Thermogravimetric analysis was used to investigate the thermal stability of epoxy before and after the addition of nanosilica. FML was prepared using the hand layup and compression molding processes by sandwiching thin aluminum alloy sheet and E-glass fiber. The FML specimens were cut using an abrasive water jet machine as per ASTM standards for determining their mechanical characteristics such as tensile strength, flexural strength, and short-beam strength. Vibrational analysis was undertaken, and the natural frequency and damping factor for the FML specimens were determined.The results revealed that the tensile strength of pure FML was increased by 7% for 3 wt% nanosilica-dispersed FML. Flexural and interlaminar shear strength was increased by 30.5% and 10.9%, respectively for the 1 wt% nanosilica-dispersed FML was compared to pure FML.

“…The effects of some parameters are discussed in detail, and some meaningful conclusions are concluded. Maras et al [26] experimentally and numerically, investigated the vibration characteristics of FML for clamped-free boundary conditions. Using the Finite Element Method (FEM) numerical results were obtained and then these results were compared with the experimental results and found results were in good agreement.…”

A high specific stiffness, high specific strength, and tailoring the properties for specific application have attracted the attention of the researchers to work in the field of laminated composites and Sandwich structures. Rapid use of these laminated composites and Sandwich structures necessitated the development of new theories that suitable for the bending, buckling and vibration analysis. Many articles were published on free vibration of beams, plates, shells laminated composites and sandwich structures. In this article, a review on free vibration analysis of shear deformable isotropic beams, plates, shells, laminated composites and sandwich structures based on various theories and the exact solution is presented. In addition to this, the literature on finite element modeling of beams, plates, shells laminated composites and sandwich structures based on classical and refined theories is also reviewed. The present article is an attempt to review the available literature, made in the past few decades on free flexural vibration response of Fiber Metal laminated Composites and Sandwich panels using different analytical models, numerical techniques, and experimental methods.

“…Developing technology has triggered to substitution of conventional materials with modern engineered materials that can offer a variety of required qualities altogether. Especially, to ensure the low emission goal and efficient use of natural resources due to the increasing environmental restrictions, without sacrificing any mechanical property, the importance of the utilization of polymer-based composite materials that are lighter than traditional alloys has been growing rapidly in the designed structures [1]. In this regard, thermoplastic-based composites with remarkable characteristics, such as being light and having good recyclability, low cost, high ductility, and adequate damping strength; are commonly employed in the aviation, automotive, marine, and petroleum industries [2], [3], [4], [5], [6].…”

Glass fiber-reinforced thermoplastic composites are continuously finding their application especially in the field of aerospace and marine due to their stiffness-to-weight advantages. Accordingly, it has gained prominence to evaluate the behavior of composites under diversified environmental conditions where vibration inputs are common. In this research, effect of various environments on the free vibration response of long glass fiber-reinforced polypropylene (PP) composites with different fiber ratios is investigated. Free vibration under an impulse response of thermoplastic composite samples is studied experimentally in a vibration test setup with fixed support. Numerical simulations are also performed through 3D FE models. The present study has revealed that the decrease in temperature increases the natural frequency of the PP composites by over 20%, exceeding 20 Hz. Moreover, whether the composites have 20 wt.% or 40 wt.% long glass fiber content, the damping factors of thermoplastic composites are highly dependent on temperature. The damping ratio distinctly decreases to below 0.008 at -70oC while it increases by over 50% at 0oC relative to the value at room temperature.
