“…Similar diameter variations have been observed in other natural fibers such as wool [55], bamboo fibers [44], sisal fiber [56], and jute fiber [57]. However, the fiber diameter distributions observed in the present study were higher than those reported by Reddy and Yang [58] and M. Siti Alwani et al [59]. Generally, the origin, quality of plant, location, weather, age, and fiber extraction method employed control the properties of natural fibers [60].…”

“…Thus, a fiber with a smaller diameter will be stronger compared to one with a larger diameter. In addition, fiber strength was found to be negatively correlated to fiber gauge length [46,59,[62][63][64]. Furthermore, as the fiber gauge length increases, the distribution of flaws also increased the probability of the presence of a larger fatal flow, which leads to the localization of stress and thereby reduces fiber strength.…”

In the present work, an investigation on the surface topography and geometry variation of bagasse fibers was correlated with their mechanical properties via image analysis. The fibers were tested under a universal tensile testing machine and the diameter of the fibers was calculated using images obtained in a digital microscope. Furthermore, surface characterization and quantification were also performed using images obtained via SEM. The results showed that the surface roughness of alkali-treated bagasse fiber increased compared to that of the untreated one. Moreover, it was observed that the diameter variation of bagasse fiber along its length and among different fibers is not only variable but also unpredictable. The tensile test results revealed that bagasse fibers showed lower stress at a rupture with considerable scatter. It can be inferred that the synergistic effect of thick bagasse fiber, bagasse fiber diameter variations along its length and among fibers, and the fiber fracture mechanism establishes a local condition for fracture and resulted in such variations in tensile properties. Finally, the results clearly showed that the two-parameter Weibull fit the experimental data fairly well (R2=0.97). The Weibull modulus (m) was found to be 1.7, indicating that the strength distribution is high.

“…Natural fibers are known for their biodegradability, renewability, low density, and excellent mechanical properties. Natural fiber composites (NFCs) are composite materials consisting of a matrix material and natural fibers embedded in it (George et al 2001;Alwani et al 2015;Jawaid and Abdul Khalil 2011). The matrix material, often a polymer or biopolymer, acts as a binder and provides cohesion and strength to the composite.…”

The physical and chemical attributes of Areca catechu fiber (ACF) were explored. ACF is attractive because of its high cellulose content at 63.2 wt%. The mechanical properties were evaluated for Areca catechu fiber-reinforced epoxy composites, in which silicon carbide (SiC) was used as filler. The studied properties included water absorption, flexural strength, impact strength, tensile strength, and hardness properties. The tensile and flexural properties improved when the filler content increased from 40 to 50 wt%, but further increment in the filler content reduced the strength values. The addition of SiC adversely affected the bending and flexural properties of the composites at 40 and 50 wt% filler content, but it positively affected the properties at 60 wt% filler content. The hardness of the composites increased with the addition of 10% silicon carbide. From the results of this study, it is recommended that the ratio of silicon carbide in the composite should not exceed 10 wt% due to agglomeration. The composites containing 10 wt% SiC can be used for outdoor applications such as decking, railing, garden fencing, cladding, and siding applications.
