“…The graph indicates that the tensile strength and tensile modulus of both types of composites increased, when the nanoclay filler was incorporated up to 5 wt%, but then subsided after further addition of nanoclay. The similar trend was also observed by Ramakrishnan et al during their investigation. The effect of the nanoclay content within the developed composites can be explained as due to the homogeneous dispersion of the nanofiller in the matrix epoxy, which plays a vital role in improving the tensile properties.…”

The tensile, flexural, and morphological properties of Napier fiber reinforced nanomodified epoxy composites were investigated. Untreated and alkali‐treated Napier fibers, as well as nanoclay and epoxy resin, were used to fabricate Napier fiber reinforced nanomodified epoxy composites by using cold press compression machines. Napier fiber was treated with 5% dilute sodium hydroxide (NaOH) solution for 6 h. Varying amounts of nanoclay filler (3, 5, and 10 wt%) were mixed with the epoxy resin prior to fabricating the Napier fiber reinforced nanomodified epoxy composites. The results of mechanical testing indicated that the alkali‐treated Napier fiber reinforced nanomodified epoxy composites incorporating 5 wt% nanoclay exhibited the highest flexural and tensile properties. Morphological analysis was then conducted to further analyze the fractured specimens following the mechanical tests. The scanning electron microscope images of the Napier fiber reinforced nanomodified epoxy composites that contained 5 wt% nanoclay revealed good interfacial bonding between the matrix and the reinforcement.

“…The water absorption pattern for NFCs follows Fickian behavior at room temperature where the water uptake process is linear initially and approaches saturation state after sufficient time duration . The kinetics and diffusion mechanism in the material can be ascertained using the following relation:

\frac{M_{t}}{M_{\infty}} = k t^{n}

This work presents the effect of chemical treatment of short jute fibers using alkali, potassium permanganate, and silane treatment on the mechanical properties of jute‐polypropylene (PP) composites. The chemically treated jute fibers were compounded at 30% weight fraction with PP granules in twin‐screw extruder, and the composite pellets were later injection molded to obtain the specimens for the study. The optimum parameters for the respective chemical treatments used in this study were followed as per the literature. The effectiveness of the chemical treatment carried out was studied using Fourier transform infrared spectroscopy and scanning electron microscopy. The mechanical characterization comprising tensile test, flexural test, impact test, and microhardness test were conducted on jute‐PP composites. In addition, the effect of chemical treatment on the water absorption kinetics of the jute‐PP composites was studied. The diffusion coefficient of the jute‐PP composite was determined using the approximate solution of Fick's model. The silane‐treated jute‐PP composites show an increase in tensile strength, tensile modulus, and flexural modulus by nearly 6%, 22%, and 20%, respectively, compared to untreated jute‐PP composite. The moisture absorption study reveals that the silane‐treated jute‐PP composite is the most effective.

“…Water absorption test: Water absorption tests were carried out on three prismatic samples with size 64 Â 12.7 Â 3 mm 3 for each case according to ASTM D 570-98 standard, under different climatic conditions of 10 C, 30 C and 60 C. The samples were taken out from the bath at regular intervals of time, that is for every 1 h, and the water content present on the specimen surface was wiped out with a dry cloth and then weighed in a high precision digital balance. The water absorption in the weight percentage (%M) was calculated by using the following equation [32][33][34][35].…”

“…where M t represents the moisture absorption at time t, M m indicated the saturated moisture absorption and k and n are the constants. In Fickian model, the diffusion coefficient (D) was one of the important parameters which show the ability of water molecules to penetrate into the samples and it can be determined by using the following equation [33,34].…”

This paper represents the first effort aimed to study the interdependence of mercerization, moisture absorption and mechanical properties of sustainable Phoenix sp. fibre-reinforced epoxy composites fabricated by compression moulding technique. The investigation was carried out by varying the fibre length (10, 20 and 30 mm), fibre volume fraction (10%, 20%, 30%, 40% and 50%), concentration of sodium hydroxide for fibre treatment (5%, 10% and 15%) and immersion temperature (10℃, 30℃ and 60℃). The fibre–matrix interface and failure mechanism was studied by using scanning electron microscopy. The results revealed that the moisture absorption rate increased with the increase in fibre length, fibre volume fraction and immersion temperature result in loss of tensile and flexural properties. The moisture absorbed samples shows 15% and 7% drop in tensile and flexural strength, respectively. However, this loss was less in mercerized fibre-reinforced composites.
