“…The damping factor usually represents the energy dissipation of the composite material under loading conditions and also it describes the relationship between the loss modulus and storage modulus. [ 44 ] Figures 14–18 show the temperature effect and bentonite nanoclay concentration on the damping factor of the polyester matrix composite at different frequencies. From Figures 14–18 it was found that the inclusion of bentonite nanoclay up to 5 wt% into the polyester resin has a lower tan δ peak when compared to pristine polyester resin and this may be due to the adhesion between the polyester and the nanometer‐sized nanoclay.…”

In this research, the effect of the addition of aluminosilicate (bentonite) nanoclay powder on the mechanical and dynamic mechanical behavior of polyester composites was investigated. Nanoclay laminates were fabricated in four different combinations, and the effect of nanofiller addition on the mechanical behaviors has been tested under ASTM Standards. The nanoclay and polyester resin were mixed using the ultrasonication process. Due to the enhanced interface between nanoclay and polyester, the flexural, tensile, and impact characteristics of laminates were boosted by clay addition. The loss modulus, storage modulus, and tan δ of the specimen were studied as a function of temperature and frequency of oscillation using a dynamic mechanical analyzer, and it was discovered that the addition of 5 wt% bentonite clay provided better strength and had the highest storage modulus than the other laminates. A morphology analysis was done on the fractured specimens through the scanning electron microscopy.

“…One of such modifications is the addition of clay at macro and nano levels, and the effects of clay addition to bio-composites have been studied by many researchers. For example, Arulmurugan and Venkateshwara [44] investigated the influence of alkali treatment and addition of 5% weight montmorillonite nanoclay as filler on mechanical and visco-elastic behaviour of jute fibre polymer composite. The produced composites showed both improved mechanical properties and an increase in the glass transition temperature from 109 to 115 • C. Hossen et al [45] studied the effect of fibre treatment and nanoclay on the tensile properties of jute fibre-reinforced polyethylene/clay nanocomposites and showed the addition of a small amount of nanoclay improved the tensile properties of the composite without compromising the weight of the composite.…”

This study investigates the feasibility of creating a clay polymer-based composite using cowpea husk (CPH) as filler for production of roof tiles. Polymeric composites were fabricated by mixing unsaturated polyester (UPT) resin with cowpea husk at different filler weights and curing. A hybrid composite was produced with the addition of 3 wt.% clay and all samples produced were subjected to flexural, hardness and dynamic mechanical analysis (DMA) tests. The effect of clay addition on the mechanical and thermo-mechanical behaviour of formulated composites was investigated. The morphological analysis of the mono and hybrid system shows a rough and coarse inhomogeneous surface with voids created due to the addition of CPH filler for the mono reinforced and clay uniformly filling the voids that were created by the CPH in the hybrid composite. It is observed that hardness, tensile modulus and flexural modulus of hybrid composites increase with an increase in the CPH contents, while the strength and flexural strength all decrease with filler content. The optimal composition was obtained using Grey relational analysis (GRA) at 18% CPH for both mono and hybrid composite. The results imply that the composite combination can be used in making rooftiles and/or also in applications where low strength is required.

“…In addition to the growth region other parameters have influence in the characteristics of the fibres, as the sowing time [6], the sowing density [7], if there is an irrigation system. Many of these parameters are being explored, but the research still is a little restrict to some types of fibres that are more common, as flax [8,9], hemp [6,10], jute [11], sisal [12] and Coir [13][14][15].…”
