“…The feasibility and value of the different natural fibers depends on their end-use markets and costs of extraction. These properties make natural fibers able to compete with glass fibers in composite materials [34][35][36]. However, there are some disadvantages that restrict the use of natural fibers in industry, such as incompatibility with specific polymeric matrices, formation of aggregates while processing, and their poor resistance to moisture [37][38][39].…”

In this study, microcellular polyurethane (PU)-natural fiber (NF) biocomposites were fabricated. Polyurethanes based on castor oil and PMDI were synthesized with varying volume ratios of sisal fiber. The effect of natural fiber treatment using water and alkaline solution (1.5% NaOH) and load effect were investigated. Biocomposites were mechanically and physically investigated using tensile, viscoelasticity, and water absorption tests. The interfacial adhesion between PU and sisal fiber was studied using SEM. Short NF loads (3%) showed a significant improvement in the mechanical properties of the PU-sisal composite such as modulus of elasticity, yield and tensile strength up to 133%, 14.35 % and 36.7% respectively. Viscoelastic measurements showed that the composites exhibit an elastic trend as the real compliance (J’) values were higher than those of the imaginary compliance (J’’). Increasing NF loads resulted in a decrease of J’. Applying variable temperatures (120–80 °C) caused an increase in the stiffness at different frequencies.

“…A composite acts hydrophilic when the silica surface of the filler is hydroxylase [24]. Hydrophilic nature of the fillers attracts and facilitates the penetration of water within the composite as described by previous researchers [3,23]. The existence of additives in the composite may cause the creation of higher void content due to additional steps involved during the fabrication process [24].…”

Using natural fibres as reinforcements in composites provides an inexpensive green alternate to its synthetic counterpart. In a similar scope, to enhance the usability of sugar palm fibres (SPF) in composites, various weight percentages (1% to 5%) of silica aerogel (SA) were infused in SPF reinforced unsaturated polyester composites. The samples were prepared using hand layup procedure followed by hot pressing at 80°C for 30 minutes. The physical properties such as water absorption and thickness swelling characteristics of the composites were investigated. The specimen of water absorption and thickness swelling were exposed to water absorption for a total of 90 days and measured on alternate days in first week. Later, the readings were taken on a weekly basis until the 3rd week and bi-weekly for the rest of immersion time. Pure SPF composites showed lowest water absorption and thickness swelling and it increased with addition of SA. The highest water absorption was recorded up to 12 % and thickness swelling was 7% in 5% SA composites. SA showed its hydrophilicity character, but the percentage of water absorption and thickness swelling is very less.

“…The values of maximum tensile strength allow the selection of MPF as a possible alternative to be used as reinforcement in bio-composite materials by overcoming fibres (Fig. 4a), such as jute [29], kenaf [30], flax [31], sisal [32] and cotton [33], used in the development of these materials. Although the module obtained shows representative variations with respect to fibres such as flax, hemp, jute, ramie, and kenaf; there are similarities between the MPF and the sisal fibre [34], as shown in Fig.…”

The characterization of natural fibres is currently used in the field of science and engineering of materials with the purpose of developing new bio-composites friendly to the environment. The goal of this research is to manufacture and characterize a bio-composite reinforced with Moriche palm fibre (Mauritia flexuosa) and to determine the thermal, mechanical and morphological properties of the fibre. Subsequently, the tensile and flexion properties of the composite was evaluated, as well as its morphology. The thermogravimetric analysis demonstrated that the fibre has hydrophilic characteristics and good stability at temperatures close to 200 °C. In the tensile test under static axial forces, its modulus of elasticity, stress and maximum deformation was determined. Its morphology, composed of the small lumen and wide cell wall with size variations, was examined with scanning electron microscopy (SEM). In the same way, the maximum tensile stress of the composite leads to the conclusion that it is viable to use this material for applications in non-structural elements, which are below 25 MPa. The results of maximum flexural strength (253.7 MPa) allow more extensive applications in doubly supported or overhanging parts subjected to concentrated or distributed loads. The microstructure obtained with SEM showed a poor adhesion between the matrix and the reinforcement.
