“…The effect of nanoclay addition on vibration characteristics studied by Rajesh et al 44 for woven banana/jute hybrid polyester and Rajini et al 39 for woven coconut sheath/polyester composite also supports the earlier finding. Natural frequency was maximum up to 2% nanoclay addition with banana/jute composites whereas 3% in coconut sheath composites.…”

“…In their work, Senthil Kumar et al. 43 have conducted experiments to explore the influence of stacking sequence on vibration behavior of short banana (B) and woven coconut sheath (C)-reinforced polyester composites. Shuffling the banana between the coconut layers provided highest natural frequency value to the polyester composite when compared to other studied composites (BBB, CCC, CCB, BBC, BCB).…”

“…Alkali and silane treatment of fibers impart increase in natural frequency values (in mode 1, from 32.53 to 39.28 Hz and 43.58 Hz). In another work, 43 authors have explored the effect of surface treatment on the banana fiber composites. In this case, negative effect on surface treatment is recorded with vibrational analysis.…”

In recent past years, results on natural fiber-reinforced composites response are seriously viewed by researcher and industrial community to ensure the real-time service. Exploration on mechanical and tribological properties of several vegetable fibers is available with literature database. Nonetheless, dynamic properties of those composites are more essential to fitting them into service. In this account, few researchers have started to experiment the dynamic stability of vegetable fiber composites at elevated temperature viz., dynamic mechanical analysis at various frequencies and thermogravimetric analysis. Perhaps, the vibration and damping analysis may bring us some good sense on structural stability of those materials. Later, researchers have started to find vibrational response of materials; even then, neither complete nor accurate results/practices are recorded. Therefore, it is indeed to look in deeply the vibrational response of natural fiber-reinforced composites towards anti-vibration applications. An attempt has been made here to review some of the literature published on vibration damping applied to natural fiber-reinforced composites by experimental and numerical methods; the effects of natural fiber reinforcement on vibrational response of both thermoset and thermoplastic polymer matrix are reviewed. Discussions on the effects of several parameters are made to bring comprehensive knowledge on vibrational response of natural fiber-reinforced composites.

“…From the previous study, it is concluded that basket-type woven composite gives better dynamic mechanical properties and free vibration characteristics compared to other weaving patterns such as plain, satin, twill and huckaback woven composite. 26–31 Therefore, banana-jute intra-ply fabric is prepared with basket-type weaving pattern as shown in Figure 1. Methyl ethyl ketone peroxide (MEKP) and cobalt naphthenate are used as catalyst and accelerator, respectively, and are mixed with the unsaturated isophthalic polyester in the ratio of 1:1:100 (by weight).…”

The influence of surface treatment (alkali, potassium permanganate, benzoyl chloride and silane) on the mechanical, dynamic mechanical and free vibration properties of intra-ply hybrid banana/jute woven fabric composite has been analyzed. Intra-ply woven fabrics are fabricated by keeping banana yarn in weft direction and jute yarn in warp direction of a basket-type woven fabric. Results reveal that the enhancement of tensile and flexural strengths of the composite due to the chemical treatment is marginal, except for the benzoyl chloride treatment. However, the chemical treatment results in better impact strength compared to the untreated composite. Tensile, flexural and impact strengths of the benzoyl chloride treatment increase by 10%, 30% and 50%, respectively, compared to untreated composite. It is evident from Fourier Transform-Infrared Spectra that benzoyl chloride treatment effectively removes the hemicellulose and lignin content. It is observed that benzoyl chloride and alkali treatment improves the dynamic mechanical characteristics. Experimental modal analysis carried out on intra-ply fabric composites reveals that benzoyl chloride treatment increases the natural frequency significantly compared to the untreated composite.

“…The addition of nanofiller often changed the relaxation behavior of macromolecular polymer chains [ 23 ]. Rajesh et al [ 24 ] reported that the incorporation of nanoclay improved the storage modulus and loss modulus but lowered the loss factor (tan delta) of banana/jute/nanoclay polyester composites, due to the improved engagement between polyester, nanoclay and banana/jute woven fibers.…”

Current work aims to study the mechanical and dynamical mechanical properties of non-woven bamboo (B)/woven kenaf (K)/epoxy (E) hybrid composites filled with nanoclay. The nanoclay-filled BK/E hybrid composites were prepared by dispersing 1 wt.% nanoclay (organically-modified montmorillonite (MMT; OMMT), montmorillonite (MMT), and halloysite nanotube (HNT)) with high shear speed homogenizer followed by hand lay-up fabrication technique. The effect of adding nanoclay on the tensile, flexural, and impact properties of the hybrid nanocomposites were studied. Fractography of tensile-fractured sample of hybrid composites was studied by field emission scanning electron microscope. The dynamic mechanical analyzer was used to study the viscoelastic properties of the hybrid nanocomposites. BK/E-OMMT exhibit enhanced mechanical properties compared to the other hybrid nanocomposites, with tensile, flexural, and impact strength values of 55.82 MPa, 105 MPa, and 65.68 J/m, respectively. Statistical analysis and grouping information were performed by one-way ANOVA (analysis of variance) and Tukey method, and it corroborates that the mechanical properties of the nanoclay-filled hybrid nanocomposites are statistically significant. The storage modulus of the hybrid nanocomposites was improved by 98.4%, 41.5%, and 21.7% with the addition of OMMT, MMT, and HNT, respectively. Morphology of the tensile fracture BK/E-OMMT composites shows that lesser voids, microcracks and fibers pull out due to strong fiber–matrix adhesion compared to other hybrid composites. Hence, the OMMT-filled BK/E hybrid nanocomposites can be utilized for load-bearing structure applications, such as floor panels and seatbacks, whereby lightweight and high strength are the main requirements.
