“…Natural fibre has unique characteristics and many outstanding advantages over synthetic fibre, which make it an attractive alternative to traditional materials [1,2]. Natural fibres such as hemp, flax, abaca, sisal, jute, henequen, kenaf, ramie, sugar palm, oil palm, pineapple leaf, banana pseudo-stem, sugarcane bagasse, coir, rice husk, wood, bamboo, chicken feathers, wool, silk and cotton have been reported as being used as fibre in polymer composites [3][4][5][6][7][8][9]. Natural fibrereinforced plastics are gaining more attention from researchers and industry due to their cost-effectiveness, lighter weight, lower abrasion of equipment and renewability, among the several benefits of natural fibre composites [10][11][12].…”

Global warming, environmental changes, and other problems have been increasing in the last decade. Researchers and scholars want to safeguard life on the earth by making ecofriendly products, like natural composite materials. Natural fibre is environmentally valuable because of its biodegradable nature. However, there is a serious problem caused by the incompatibility between fibre and matrix. In this work, sugar palm fibre was combined with thermoplastic polyurethane composites after treatment with different concentrations of sodium hydroxide from 2 to 6% to enhance the compatibility between them. An extrusion machine was used to combine 30% by weight of the sugar palm fibre and 70% by weight of thermoplastic polyurethane composites. The temperature, rotation velocity, and fibre size were fixed at (180-190-200°C), 40 rpm and 250 µm respectively. The composite was characterized according to ASTM D638. The sodium hydroxide treatment of the fibre could provide a good tensile modulus of 440 MPa at 2% of NaOH, and strain of 41.6% at 6% NaOH of the composite. However, the tensile strength was decreased, where the highest amount of 5.49 MPa recorded at 6% NaOH. Meanwhile, the tensile modulus and strain of the composites are found to be much better than those of untreated ones. In contrast, the tensile strength was still not improved.

“…The result of weak bonding between the water absorbing filler and the water resistant matrix polymer obstructs the stress propagation, and thus reduce the tensile strength when the filler loading increases. In addition, poor dispersion results in filler clouding and drops in tensile properties (Hardinnawirda and Sitirabiatull, 2012). Maximum tensile strength of 13.2Mpa is noticed with 2 nd sample i.e., 5% filler.…”

The purpose of this study is to improve mechanical property of long coir fibers of length 100-150mm using well graded sawdust filler and to scrutinize viability when subjected to distill and sea water conditions for calculated duration. Study involves fabricating eco-friendly composite specimens by maintaining optimum percentage of natural fibers and fillers without compromising on mechanical strength. The composites of different proportions by percentage of matrix (85%, 80%, 75%, 70%), reinforcement (15%, 15%, 15%, 15%), and filler (0%, 5%, 10%, 15%) by mass is developed by hand layup method and compared for their mechanical properties in dry, distilled and sea water conditions. Mechanical properties of coir composite materials improved in addition to sawdust fillers up to certain percentage. In dry condition tensile, flexural and hardness was observed. A maximum tensile and flexural modulus of 7.61Gpa and 2.16Gpa respectively was observed. Higher water absorption was noticed in specimen with higher filler percentage than the specimen with no filler. This is due to hydrophilic nature of sawdust and coir. Specimens immersed in distilled and sea water observed a slump by certain percentage in their strength with increase in fillers. Efficient utilization of filler has improved mechanical performance up to certain percentage when compared to specimen with no filler. As the filler percentage increased above 5% due to the higher fiber length and cluster behavior of coir, resistant in resin penetration was observed as a result specimen turned out to be more and more redundant.

“…Hardinnawirda and Aisha [16] reported that the tensile strength of the rice husk composites moderate increased for the 25 wt% filler loading, the values ranged between 12-16 MPa. Meanwhile in this study the tensile strength was obtained between 32.53 -36.26 MPa at fiber weight fraction 20 -30%.…”

Abstract-Indonesia as a tropical agricultural country has great potential to develop and utilize fiber derived from agricultural waste. Rice husks are an important by-product of rice milling process that can be used as reinforcement in composite products. The purpose of this study was to examine the mechanical properties of rice husks fiber polyester composites. Composites were produced with unsaturated polyester resin as the matrix and rice husks as fiber. The matrix type is polyester Yukalac 157 BQTN, and methyl ethyl ketone peroxide as catalyst. Composites were made by hand lay-up techniques, with the variation of fiber weight fraction 20, 30, 40 and 50%. Tensile test specimens were made according to the ASTM D3039, and flexural test specimens according to the ASTM D790M. The results showed that the tensile and flexural strength of the composites increased when the fiber weight fraction increased.Index Terms-Flexural strength, polyester, rice husks, tensile strength, weight fraction.
