“…[38] Schirp and Stender reported [39] that the flexural strength of hemp fiber-reinforced polypropylene (PP) composite has performed better than that of wood fiber-reinforced PP composites due to the higher aspect ratio of hemp fibers. In addition to this, the findings reported by Jeyanthi et al [40] indicate that the type of matrix and fiber orientation of UD Kenaf has a significant effect on the flexural strength and modulus values. Thus, it is clear F I G U R E 1 2 (A) Force versus extension curves of jute-banana PF NFHCs, (B) fracture toughness values, and (C) fractured jute-banana PF NFHCs.…”

Jute and banana fibers are biodegradable green fibers being increasingly used to replace synthetic fibers in fiber-reinforced polymer composites. Integration of jute and banana distinct natural fibers has the potential to improve composite performance in secondary structural applications. In this study, an equal quantity of unidirectional jute and banana fibers with four different fiber orientations [(0/0) 3s , (0/45) 3s , (0/90) 3s , and (+45/À45) 3s ] was embedded in phenol formaldehyde resin to make hybrid laminates using the hot press method. Tensile, flexural, impact, interlaminar shear strength (ILSS), and single-end notch bend tests are performed in accordance with the ASTM standards to evaluate the effect of fiber orientation on natural fiber hybrid composites (NFHCs).Experimental results revealed that changing the fiber orientations [(0/0) 3s ] leads to a major impact on reducing the mechanical properties of NFHC laminates to the extent of 39%. Furthermore, the tensile strength, Young's modulus, impact and ILSSs, and fracture toughness were found to be 37% higher for the (0 /0 ) 3s composite. Additionally, tensile, flexural, and impact fractured specimens were examined by scanning electron microscopy to understand the fiber-matrix failure behavior due to inter-ply orientation in NFHCs.

“…The advantages of using spun yarn to produce LFT natural fiber pellet are high fiber loading content and low variation of fiber content when compared with conventional compounding processes. To obtain the highest loading content, a number of natural fiber yarns are twisted together and passed through the impregnation die to produce long rods, which can be cut to obtain the pellets …”

Two types of long jute fiber pellet consisting of twisted-jute yarn (LFT-JF/PP) and untwisted-jute yarn (UT-JF/PP) pellets are used to prepare jute fiber-reinforced polypropylene (JF/PP) composites. The mechanical properties of both long fiber composites are compared with that of re-pelletized pellet (RP-JF/PP) of LFT-JF/PP pellet, which is re-compounded by extrusion compounding. High stiffness and high impact strength of JF/PP composites are as a result of using long fiber. However, the longer fiber bundle consequently affects the distribution of jute fiber. The incorporation of 10 wt % glass fibers is found to improve mechanical properties of JF/PP composites. Increasing mechanical properties of hybrid composites is dependent on the type of JF/PP pellets, which directly affect the fiber length and fiber orientation of glass fiber within hybrid composites.

“…The major reason for replacing the glass fibre with that of natural fibres is that the production of natural fibres has less environmental impact compared with the glass fibre production. Jeyanthi and Janci Rani [19] discussed that, during this decade natural fibres are acting as a strengthening agent in polymer composites for varieties of applications in automotive industries, structures and consumer goods. This study is used to examine the mechanical properties and its surface morphologies using SEM for natural woven alovera, sisal and kenaf natural-fibre-reinforced epoxy hybrid composites.…”

“…Mechanical properties are experimentally studied for alkali-treated kenaf-fibrereinforced polyester composite processed by vacuum infusion technique and the properties are found to be amplified [18]. Bumper beams and front-end modules prepared with hybrid kenaf/glass-reinforced material might be utilized in auto-industries by developing the impact properties as well as by diminishing the thickness and beam curvature, and strengthening the ribs [19]. In this research work an effort has been made to study the mechanical properties of hybrid woven alovera/sisal/kenaf-fibre-reinforced epoxy composites along with scanning electron microscopy (SEM) analysis.…”

The go-green concept results in multipoint focus towards materials made from nature; easily decomposable and recyclable polymeric materials and their composites along with natural fibres ignited the manufacturing sectors to go for higher altitudes in engineering industries. This is due to the health hazard and environmental problems faced in manufacturing and disposal of synthetic fibres. This study was undertaken to analyse the suitability of new natural fibre as an alternative reinforcement for composite materials. In this paper, tensile, flexural and impact test is made for the woven alovera and kenaf (AK), sisal and kenaf (SK), alovera, sisal and kenaf fibre hybrid epoxy composites (ASK). The composite laminates are made through a hand-layup process. The surface analysis is studied through scanning electron microscopy. From the investigation the SK hybrid composite shows good tensile property, AK hybrid composite shows better flexural property and the best impact strength is observed for ASK hybrid composite. The natural fibres slowly replace the synthetic fibres from its environmental impact, marching towards a revolution in engineering materials.
