“…Currently, nonwoven composites reinforced with cellulosic fibers have been used in the nonstructural applications in automotive industries . 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 . Therefore, it is necessary to remedy the shortcomings through chemical treatments to modify the fiber structure in order to achieve the exemplary mechanical properties as well as reduce the moisture uptake.…”

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.

“…The potential for GLARE to revolutionise engineering has recently been demonstrated through its adoption in the upper fuselage skin of the Airbus 5 A380. [7][8][9][10][11][12] Among natural fibres, flax emerges as the strongest contender because of its moderate specific mechanical properties, "green" (renewable and biodegradable) credentials, and lower processing energy. GLARE is arguably a beneficial engineering material that can deliver fatigue-resilient transport vehicles with improved fuel efficiency and reduced greenhouse emissions.…”

“…GLARE is arguably a beneficial engineering material that can deliver fatigue-resilient transport vehicles with improved fuel efficiency and reduced greenhouse emissions. [9][10][11][12] Previous studies aimed to address the noticeable lack of fatigue data on plant fibre composites, which currently imposes limitations on the prospective use of these materials in fatigue-critical engineering components. As well as their respiratory 6 and dermatological irritant nature, glass fibres have also been cited for adverse environmental and occupational health impact, particularly in relation to the emission of toxic pollutants during their processing.…”

Fatigue Fract Eng Mat Struct

Damage progression and failure characteristics of open‐hole flax fibre aluminium laminate (flax‐FML) specimens subjected to quasi‐static tensile or tension‐tension fatigue loading were experimentally investigated. Notched and unnotched flax‐FML composites exhibited brittle fracture with little or no fibre pull‐out and minimal delamination at the aluminium/adhesive interface. The flax‐FMLs were tested to failure under tension‐tension fatigue loading conditions (R ratio of 0.1; frequency of 10 Hz; applied fatigue stresses ranging between 30% and 80% of the respective ultimate tensile strength values). The fatigue cycles to failure decreased with the increase in the applied fatigue stress and hole diameter. A phenomenological modelling technique was developed to evaluate the fatigue life of an open‐hole flax‐FML composite. Fatigue tests on specimens subjected to a maximum load equivalent to 35% of the respective tensile failure strength were interrupted at around 85% of the corresponding fatigue life. The accumulated fatigue damage in these specimens was characterised using X‐ray computed tomography. For benchmarking purposes, the fatigue performance and related damage progression in the flax‐FML composite were compared with those of the glass‐FMLs.

A compendious review on fatigue properties of the bio‐nanocomposites

et al. 2022

In this present work, a review of fatigue strength on bio‐nano composites was presented. Generally, the biocomposites possessed higher fatigue strength than the conventional materials. Because the propagation in biocomposites can be arrested due to their internal structure, whereas the damages occur in the matrix and/or at the fiber/matrix interface region. In the case of conventional materials, the cracks would rapidly grow until a catastrophic failure occurs. Thus, the S–N curves of composites show a flatter curve when compared to the conventional materials. In terms of fatigue properties, conventional fiber‐reinforced composites (e.g., glass and carbon‐reinforced composites) were more extensively studied than bio‐based reinforced composites. Examining the fatigue properties of materials is significant for all engineering‐based applications. Because the fatigue failures can occur below the ultimate tensile strength of materials. However, the fatigue performance of the composites can be enhanced by improving the fiber‐matrix interfacial bonding resulting from surface treatment of fibers and incorporating nanofillers within the matrix, and so forth. Since the nanocomposites have a larger surface area and aspect ratio, they are preferred to use in many applications: aerospace, automotive, biotechnology, construction, and building, electronics, marine, and packing industries. Thus, this chapter starts with the unique advantages of bio‐nano composites. Then, the fatigue properties of bio‐nano composites, the significance of the S–N diagram, and the pattern of fatigue testing were discussed. In order to understand the fatigue behavior, several factors such as structure, fillers, fabrication techniques, and so forth were included. Challenges of fatigue strength of biocomposites were also summarized.
