“…is trend is consistent with previous studies that produced banana/sisal and cattail/ wheat straw polymer-reinforced hybrid composites [29,31] and can be attributed to higher compatibility and uniform distribution of fibres in the matrix resulting in good transfer of stress between the matrix and the fibres. Decrease in flexural, tensile, and compressive moduli of the composites at higher sisal fibre loading could be attributed to fibre agglomeration and therefore poor fibre-matrix bond [32].…”

“…e impact strength of the hybrid composites improved steadily as the percentage of the sisal fibre increased from 0 to 100% by 58.72% with a maximum value of 34.40 kJ/m 2 at 100/0 sisal/cattail ratio. is trend is concordant with previous studies in which sisal/polymer composites exhibited better impact properties [9,16,31,33]. e gradual increase in impact strength with increase in the sisal fibre loading could be due to its porous nature and the high microfibrillar angle of sisal fibres [29].…”

Due to environmental and energy conservation concerns, a thrust towards low-cost lightweight materials has resulted in renewed interest in the development of sustainable materials that can replace nonbiodegradable and environmentally unfriendly materials in reinforced composites. In this study, mechanical properties of a hybrid composite consisting of polyester resin reinforced with a blend of sisal and cattail fibres were evaluated. The composite was fabricated using a hand lay-up technique at varying hybrid fibre weight fractions (5 to 25 wt%) while maintaining a constant fibre blend ratio of 50/50. Composites were also prepared at a constant fibre weight fraction of 20% while varying the fibre blend ratio between 0 and 100%. Fabricated composites were then characterised in terms of flexural, tensile, compressive, and impact strengths following ASTM and ISO standards. Results showed that, at a constant fibre blend ratio of 50/50, there was increase in the mechanical properties as the fibre weight fraction increased from 5 to 20%. At a constant fibre weight fraction (20%), a positive improvement in flexural, tensile, and compressive properties was registered as the fibre blend ratio varied between 0 and 75% with optimal values at a sisal/cattail ratio of 75/25. The current study suggests that blending sisal and cattail fibres for production of polyester composites yields hybrid composites with enhanced mechanical properties.

“…The experimental results revealed that the Portland cement (10 wt%) imparts high flexural strength and stiffness to the composites and therefore could be used for aircraft and structural applications. Recently, Akash and coworkers [178,179] fabricated low-cost sisal hybrid composites and thoroughly study its mechanical and water absorption properties in terms of fiber loading.…”

In recent years, researchers across the globe have switched from synthetic fibers to natural fibers for the fabrication of composites. The desirable properties of natural fibers which attracted researchers, as well as academicians, are its low density, easy availability, environmentally friendly nature, biodegradability, and high specific strength. Hence in the last decade, there is tremendous progress in the development of natural fiber-reinforced composites for various industrial applications. The current review focused on the recent progress in natural fiber-reinforced polymer composite. The natural fibers discussed in this review are derived from leaves, namely pineapple, sisal, and abaca. The extraction and processing of these fibers are briefly outlined. The properties and application of natural fiber-reinforced composites are also addressed in this review. One of the drawbacks of natural fiber is its poor compatibility with the polymer matrix. The different treatment methods to improve the fiber-matrix interaction are also summarized in the present review.

“…Coir/sisal hybrid composite has been evaluated its tensile and flexural strengths. This result promised that these fibers has potentially for reinforcing composite due to cheap and high strength to weight ratio [13]. Then, Yusoff et al [14] investigated hybrid composite reinforced by kenaf, bamboo and coir fibers.…”
