“…These fibers are typically combined with a thermoplastic matrix, which can be made from materials like polypropylene, polyethylene, rubber or nylon. 14,15 One of the key benefits of natural compliant thermoplastic composites is their sustainability. The natural fibers used in these composites are renewable and biodegradable, making them an eco-friendly alternative to traditional composites that are made from nonrenewable materials like carbon fiber or fiberglass.…”

This experimental study investigates the three-body abrasive wear behavior of jute/natural rubber flexible green composite under both dry and lubricated conditions. The composite material is prepared using a layering and compression method. A three-body abrasion tester is used to conduct the wear testing under various loads. The use of a lubricant further enhances the wear resistance of the composite, reducing the wear rate and friction coefficient. Mass loss of Jute/Rubber/Jute, Jute/Rubber/Rubber/Jute and Jute/Rubber/Jute/Rubber/Jute in lubricated wear condition is 44.44%, 15.87% and 29.96% less compared to dry wear condition. Wear mechanisms of the composite material are analyzed using scanning electron microscopy (SEM), revealing the presence of fiber breakage, and adhesive wear. Overall, this study provides valuable insights into the abrasive wear behavior of jute/natural rubber flexible green composite and its potential applications in various industrial sectors.

“…[3][4][5][6][7][8][9][10][11][12][13] Natural fibres exhibit various advantages like environmental friendliness, are available at a lower price, has low density, sufficient specific strength, stiffness and toughness. 14 Such advantages of natural fibres have made them potential substitutes for artificial fibres, 7,9,11,13,[15][16][17][18][19][20][21][22][23][24][25] and naturally available fibres are widely used in the manufacture of automobile interiors. 26,27 However, they also exhibit a few cons, such as water absorption ability and inferior mechanical properties compared to synthetic fibres.…”

The present study explores the possible usage of the rubber crumb as a filler in jute-reinforced polymer matrix composites for structural applications. The rubber crumb with different weight percentages of 1.5, 3 and 5 was used for manufacturing the hybrid composites using the hand layup method, and their physio-mechanical properties were compared with the unfilled jute epoxy composite. The results revealed that the addition of a rubber crumb helps to overcome the disadvantage of water absorption by natural fibres since the water absorption of the composite filled with 5 wt% of rubber crumb reduced by 2.6 times compared to the unfilled composite. However, the density of the composites was found to increase with the addition of a rubber crumb. The tensile strength and flexural strength of the composite with 3 wt% rubber crumb was found to be better and was found to be increased by 9.38% and 42.37%, respectively, compared to the unfilled composite. The impact strength of the composite with 5 wt% of rubber crumb was the highest, and it was improved by 16.29% compared to the unfilled composite. The MADM approach, namely the VIKOR method, is successfully implemented to select the best configuration of the proposed hybrid composites. The effect of chemical treatment of the fibre on the winning composite from the MADM approach is further evaluated for its thermal conductivity and thermal resistance. This work can be a benchmark for using and converting the waste tyre rubber into the rubber crumb in polymer matrix composites to enhance their mechanical properties. It can also guide the designers in implementing the MADM approach to select appropriate composite selection when there are multiple conflicting criteria.

“…Other natural fibers have also been developed as reinforcement materials in composites, e.g. jute [8], leaf of pineapple [8], hemp [9], sisal [10], etc Of many agriculture products in Indonesia, salak (Salacca zalacca) is Indonesian native fruit and can be widely found in the Island of Java and Sumatra. Currently, only its fruit is used and the rest has not yet been used for daily and engineering application.…”

Although Indonesia is abundant supply of salak (Salacca zalacca) fruit, bark of salak is not yet advanced utilized. This work therefore chracterized its fiber and process it into polymer matrix composites. The study was conducted using varied chemical treatments. Delignification using NaOH solution with concentration of 1%, 5%, 10% with 3 hours immersion time. Bleaching treatment was using H2O2 media with varied immersion time at 30, 60 and 90 minutes. Tensile tests, impact tests, microscopic image test using scanning electron microscopy (SEM) and chemical composition test using fourier-transform infra-red (FTIR) spectroscopy were carried out in this work. This work showed that optimal delignification treatment can be found when 5% NaOH concentration was used. The corresponding ultimate tensile strength and impact strength were 25.47 MPa and 11.95 kJ/m2, respectively. The optimal bleaching treatment was 90 minutes immersion. The results of SEM image analysis showed that the salak midrib fiber composite without treatment has a lousy interface. Meanwhile, fiber with delignification treatment only has reasonable good interface and fiber with delignation treatment followed by bleaching treatment has excellent interface. FTIR test results showed that the salak midrib fiber composite without treatment had a cellulose component although hemicellulose and lignin levels still dominated. The delignification treatment had succesfully broken the lignin-specific C = O bond but still could not eliminated hemicellulose and lignin bond. In comparison, bleaching treatment reduced intensity of OH intensity, CH and CO which are typical hemicellulose and lignin functional groups. Based on the results of the study, salak midrib fiber with delignification chemical treatment using 5% NaOH for 3 hours followed by bleaching treatment using 2% H2O2 for 90 minutes was the best treatment.
