“…The surface modification of natural organic fibers is needed to enhance the compatibility and it has been inferred that the interfacial bonding is increased b according to the results of the viscoelastic behavior of the composites [4][5][6]. To investigate the viscoelastic behavior and structural properties of polymeric and metal matrix composite materials with the aim of determination their relevant damping and stiffness characteristics in our regular applications, dynamic mechanical analysis (DMA) was employed [7][8][9][10]. These dynamic properties obtained over a range of temperatures and frequencies are noteworthy, studies showed that the stacking sequence and fiber orientation influences the dynamic mechanical characteristics of hybrid polymeric composites [11][12][13][14][15].…”

In this modern era, the natural fibers usage in automobile and construction sectors has been increased. The goal of the current work was to investigate the fiber orientation effect on dynamic mechanical properties of hybrid Pineapple Leaf Fibre (PALF) hybridized with basalt reinforced epoxy composite at changing vibration frequencies. Hand Lay-up technique was used to manufacture the composites by keeping the unidirectional basalt fabric as an outer layer by keeping PALF as inner layer followed by static compression method. Tensile and flexural moduli were also determined apart from storage modulus (E′) and damping factor (tan δ) for different PALF fiber angles. The results exemplified that not only the storage modulus and loss factor but also glass transition temperature (Tg) as well found to increase with frequency and also the fiber orientation angle has a greater impact on dynamic and static properties.

“…This is due to its low loss modulus (energy dissipation capacity) relative to its storage modulus (energy storage capacity). The general rise in damping capacity as temperature increases may be attributed to enhanced particle mobility and interface/ boundary sliding [17,42]. This mechanism appears somewhat inhibited for the Al-Zn reinforced with 8 wt.% Cu.…”

“…Metallic materials are generally known to possess relatively low damping capacity than ceramics so their selection will naturally arouse concern on how they influence damping capacity of the AMCs. Although works have shown that the damping capacity of AMCs reinforced by metallic particles fall within the same range as that of ceramic reinforced AMCs [16,17], the studies are limited in number for generalizations to be made. Moreover, the damping properties are known to be material system sensitive [18].…”

The structural characteristics, mechanical and damping properties of stir-cast Al-10 wt.% Zn based composites developed using 6 and 8 wt.% Cu, and 8 wt.% SiC particles as reinforcements, were investigated. The low porosity (<4%), near absence of dissolved Cu in the Al-Zn matrix, and marginal presence of melt reaction-induced intermetallic phases, attest to the soundness of the castings. Besides hardness, the strength parameters − ultimate tensile strength (149.33 MPa and 138.64 MPa) and specific strength (54.3 MPa cm3 g−1 and 51.16 MPa cm3 g−1) − of the Al-Zn composites reinforced with 6 and 8 wt.% Cu, were superior to that of the unreinforced Al-Zn alloy (103.47 MPa) and the 8 wt.% SiC reinforced composite (130.5 MPa). The fracture toughness (17.32 MPa m1/2 and 13.66 MPa m1/2) and percentage elongation (15% and 12.5%) of the 6 and 8 wt.% Cu reinforced Al-Zn composites, also surpassed that reinforced with SiC (KIC − 12.28 MPa m1/2; % εf − 9.5%). Improved matrix/particles interphase bonding and the inherent ductile and tough nature of Cu over SiC, were cited responsible for the improved strength-ductility-toughness balance of the Al-Zn/Cu composites over that reinforced with SiC. The damping properties were generally temperature sensitive, with all compositions exhibiting increase in damping capacity at test temperatures 100–200 °C.

“…Lu et al [7] performed DMA on BFRP surfaces. DMA was used in the form to examine the viscoelastic nature and structural properties of polymer-metal matrix composites in order to evaluate their respective damping and rigidity characteristics [8][9][10][11]. Research demonstrates that the piling pattern and fiber orientation influence the complex mechanical properties of the composite hybrid polymer.…”

This article focuses on the viscoelastic behaviour of the anamide composites using a dynamic mechanical study developed by hot compression moulding technology at higher temperatures. The frequency range for this analysis is 1 Hz. In the nitrogen atmosphere, thermogravimetry analysis differential scanning calorimetry was used to investigate the thermal stability of composite laminates with various fiber orientations. The findings showed that a glass transition temperature close to 100°C can be achieved at 1 Hz to increase the fiber orientation of the basalt fiber-enhanced anamide compounds. Through the thermo-gravimetric analysis experiments, the excellent thermal stability of composite laminates at temperatures above 600°C was conspicuous. Analysis using the Fourier transform infrared (FTIR) spectroscopy envisioned the surface chemical properties of anamide films at various fiber orientations, and the interaction properties between fiber and matrix were determined. Scanning electron microscopy on composite laminate surfaces proclaimed that the interface relationship between the basalt fiber and the anamide material is superior with FTIR findings being assisted. The findings demonstrate that composite laminates may be a good replacement for high-performance and high-temperature applications since they are thermally extremely robust with great rigidity.
