“…Karnataka is largest areca nut producing state in India, which has a share of around 50% of the whole areca production in the country. Chemically treated areca bre reinforced epoxy composite provides better impact properties [26]. Physio-mechanical properties of hybrid betel nut (areca catechu) short bre/seaweed polypropylene composite has been studied previously.…”

The present study was aimed at investigating the e ect of incorporating areca nut nano ller on the tribological behaviour of coir reinforced epoxy based polymer matrix composite. Areca nut nano ller was produced by grinding followed by ball milling. Particle size analyser con rmed that the size of nano llers obtained was in the range of 20{100 nm. Composites with di erent weight percentages of nano ller (0%, 5%, and 10%) were studied for their mechanical and tribological behaviours using pin on disc rig. Tensile, exural, and inter-laminar shear and impact tests were carried out on the proposed composite. Taguchi's technique was used to analyse the e ects of various factors on the tribological behaviour of the composite. The results showed that inclusion of areca nut nano ller enhanced the micro hardness of the composite. Moreover, it rst increased the tensile strength by up to 5% and then, there was a decrease in tensile strength. Flexural strength signi cantly increased with increase in ller percentage from 0% to 5%, but the variation of exural strength from 5% to 10% was negligible. Inclusion of ller had negligible e ect on the inter-laminar shear strength of composites. Impact strength and wear resistance of the composite were enhanced with incorporation of ller.

Application of natural fiber-polymer composites (NFPCs) in different industrial applications provides competitive edge due to their lightweight, higher specific mechanical properties than glass fibers, sustainability, and lower cost involved in production. There are certain challenges associated with natural fibers and their reinforcement in composites such as poor bonding between the fibers and matrix due to their contradictory nature of characteristics, moisture absorption, lower thermal properties, and poor interfacial adhesion between the natural fiber and polymer matrix. The challenges involved in NFPCs need to be overcome to produce materials with relatively equivalent properties to those of conventional composites and other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and their sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs, is needed for better understanding of the behavior of NFPCs. This work provides the information and holistic view of natural fiber-reinforced composites based on the results obtained from modification techniques, with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix, and enhanced mechanical and thermal properties in the composites.

“…The hydroxyl group present in the filler reacted with the sodium hydroxide during alkali treatment. The partial removal of lignin and hemi-cellulose of the natural filler embedded in the rubber matrix resulted in the low resistance to stretching during tensile deformation, improving the elongation at break of the composites (Dhanalakshmi et al 2015). Figures 6 and 7 show that moduli at 100% elongation (M100) and 300% elongation (M300) were lower for the NR composites with treated PKS than those of the untreated PKS/NR composites.…”

Effects of alkali treatment of palm kernel shells (PKS) were investigated relative to curing characteristics, tensile properties, and fatigue of PKSfilled natural rubber (NR) composites. The PKS powder was subjected to alkali treatment using 5% sodium hydroxide. The treated PKS was incorporated into the NR composites during compounding, with the concentrations of the composites ranging from 5 to 20 phr. The properties of treated PKS-filled NR composites were compared with those of untreated PKS-filled NR composites. The cure times, scorch times, and maximum torque values were all lower for alkali-treated PKS/NR composites compared with those of untreated PKS/NR composites. Tensile strength and elongation at break were higher for treated PKS composites, while the moduli (M100 and M300) were lower than those of untreated PKS/NR composites. The fatigue tests for treated PKS/NR composites also showed higher fatigue values than the untreated PKS/NR composites. Scanning electron microscopy revealed that the higher tensile strength, elongation at break, and fatigue values of treated PKS/NR composites were due to the removal of hemicellulose and lignin in PKS fillers. This removal increased in the surface roughness of the filler and led to improved rubber-filler adhesion.
