“…Many research studies have been discussed natural fiber as reinforcements for developing high‐performance lightweight applications like electronics appliances, automotive, aerospace, and construction industries 9–11 . However, cellulosic fibers play vital roles to produce lightweight materials as compared to glass fiber and such fibers are promising to reduce energy consumption 12 . In automobile industries, the weight of the materials played a vital role to reduce energy consumption and it was evidenced that a 10% reduction of vehicle weight possesses a 7% reduction in fuel consumption 13 .…”

Natural fibers are exceptional renewable resources to develop biocomposite materials for reducing the negative effects on the environment and producing economical and lightweight materials for load bearing semi‐structural applications. The present study is an attempt to develop kenaf/pineapple reinforced bio‐epoxy biocomposite and investigates thermo‐mechanical and viscoelastic properties under accelerated weathering conditions. The compression molding technique is used to develop biocomposite with four different arrangements of kenaf/pineapple laminates. To perform accelerated weathering, laminates are exposed to ultraviolet radiation and humidity conditions with extreme temperature in weathering tester machine. The tensile, flexural, impact, thermogravimetric analysis, thermal conductivity, viscoelastic properties, and water absorption tests are performed before and after accelerated weathering. The results revealed that the hybridization of kenaf/pineapple laminates showed better interfacial strength and stiffness while reducing the moisture sensitivity under accelerated weathering conditions. The morphology and fracture behavior of biocomposites are examined with scanning electron microscopy.

“…In the automotive field, it has been evidenced that the reduction in vehicle weight by 10% is able to reduce fuel consumption up to 7% . In this context, it should be emphasized that the cellulosic fibers possess lightweight characteristic which is even lower than glass fibers, and hence, such fibers have the greater potential in reducing the energy consumption . Currently, nonwoven composites reinforced with cellulosic fibers have been used in the nonstructural applications in automotive industries .…”

[10] Currently, nonwoven composites reinforced with cellulosic fibers have been used in the nonstructural applications in automotive industries. [11] In spite of these advantages, the main challenges of using natural fibers include incompatibility with thermoplastic matrix, relatively low strength, batch-to-batch variability, and high moisture sensitivity.…”

Hybrid composites have shown innumerable benefits to the research communities in terms of environmental friendliness and mechanical properties. This research study presents the mechanical characterization and moisture uptake of kenaf/pineapple leaf fiber‐reinforced polypropylene hybrid composites with several relative fiber ratios. A comparison was also made between nonhybrid and hybrid kenaf/pineapple leaf fiber‐reinforced composites to investigate the hybridization effect. In this work, the composite materials were fabricated via the hot compression technique. Mechanical tests were performed to obtain the tensile, flexural, and Charpy impact properties of nonhybrid and hybrid kenaf/pineapple leaf fiber‐based composites. The water absorption characteristics were then obtained by immersing the composite materials in the water until the saturation point was reached. The findings concluded that the mechanical properties and moisture uptake behaviors of the composites were improved through the hybridization. The hybrid composites with a relative fiber ratio of 25:75 were particularly promising with the improvement of 10.90% in tensile strength; 16.13% in flexural strength; and 6.80% in impact strength in both flatwise and edgewise orientations compared to nonhybrid kenaf‐based composites. Meanwhile, the diffusion coefficient of hybrid composites (25:75) was 56.12% lower than nonhybrid pineapple leaf fiber‐based composites. Thus, the results indeed demonstrated that the balance between mechanical properties and moisture sensitivity can be obtained through the hybridization of kenaf and pineapple leaf fiber in the composite materials.

Fibre metal laminates are advanced sandwich materials that offer various outstanding properties over conventional metallic alloys and composites. This research study intends to investigate the effects of weaving architectures and stacking configurations on the mechanical properties of fibre metal laminates based on kenaf/pineapple leaf fibre. Fibre metal laminates were fabricated through the hot moulding compression technique. Mechanical tests were performed on the kenaf/pineapple leaf fibre-based fibre metal laminates. In accordance with the findings obtained, hybridisation had led to the improvement in the mechanical properties of fibre metal laminates in comparison with [K/K/K] fibre metal laminates. Overall, twill woven-ply [P/P/P] fibre metal laminates showed the highest tensile and flexural strength, which was 14.53% and 33.50% higher than twill woven-ply [K/K/K] fibre metal laminates, respectively. Besides, the twill woven-ply [P/P/P] fibre metal laminates also displayed the highest impact strength and indentation properties compared to other non-hybrid and hybrid fibre metal laminates. When comparing the fibre metal laminates with different weaving architectures, twill woven-ply fibre metal laminates were shown to have higher mechanical properties over those of plain woven-ply fibre metal laminates.
