Summary: Compared to conventional dew retting, enzymatic retting has the potential to control fiber extraction process and produce high quality plant fibers. This study investigated the effects of enzyme concentration and retting duration on the bond strength and fiber fineness of flax fibers. The results showed that both enzyme concentration and time significantly affected the bond strength, while only retting duration had a significant effect on fiber fineness.

Summary: In this study, the researchers experimentally investigated the morphological, physical, and tensile properties of flax at single fiber, yarn, and unidirectional fabric scales. They found that the measured properties and their variability were scale-dependent. The tensile strength and modulus of elasticity decreased gradually with scale, and the variability decreased from fibers to yarns to fabric. The study recommends considering these differences in multi-scale analysis of flax reinforcement. The results can be used for better design and preparation of plant-based natural fiber reinforced polymer composites.

Summary: An optimized new fiber architecture was developed to improve the mechanical performance of natural fiber-based thermoplastic composites. Short jute fiber-based composites showed significant improvement in mechanical properties compared to other natural fiber architectures. The use of chemical treatments on jute fibers and the application of a low-cost production process contributed to the enhancement of the composites' mechanical properties.

Summary: The physical and mechanical performance of natural fiber composites can be adjusted by combining them with synthetic fibers. Jute fibers are cost-effective and readily available in some countries, and their usage also benefits socially marginalized individuals who rely on this plant. This study examines the impact of hybridization on the properties of jute/glass and jute/carbon laminates with polyester resin. Various laminates were created using unidirectional jute, E-glass, and carbon fabric reinforcements through vacuum infusion. Tensile, flexural, and short beam tests were conducted according to ASTM standards. The hybrid composites generally exhibited intermediate properties compared to the non-hybrid laminates comprising only two components. The mechanical properties of the hybrid composites were 50-75% lower than those of the pure glass and carbon composites, but 30-300% higher than the pure jute composite. The number of synthetic fiber layers in the hybrid laminates played a more significant role in determining the properties rather than the arrangement. Varying the number of jute fabrics allowed for the desired combination of stiffness and strength for different applications. Moreover, hybrid laminates with more synthetic fiber layers exhibited superior hygroscopic performance.

Summary: This study investigates the influence of stacking sequences and hybridization on the mechanical and water absorption properties of woven flax/bamboo hybrid composites. The results indicate that the stacking sequence plays a crucial role in defining the behavior of these composites, with the optimum stacking order being B/F/F/B. Computational analysis enables the prediction of critical stresses and failures in each layer during interlaminar shear strength testing.

Summary: The mechanical properties of flax/basalt/E-glass fibers reinforced epoxy composites were studied in this research, which investigated the effects of fiber relative amounts and stacking sequence on the tensile, flexural, and impact properties. The results showed that replacing partial laminas with basalt and/or glass fiber reinforced epoxy laminas could enhance the tensile, flexural, and impact strengths. Additionally, incorporating high strength fibers to the outer layers of the composite improved flexural and impact resistances, while having the opposite effect on tensile properties.
