“…A tensile test was performed on reddish shell bean fiber with 20 mm length with the use of a universal testing machine. In literature, it is reported that 20 mm of gage length indicates maximum tensile strength, and the test was achieved with 20 mm of gage length [12]. The ultimate tensile strength of reddish shell bean fiber corresponding to 20 mm length was calculated as 111 MPa which is equiparable with Kigelia Africana [41], Sansevieria ehrenbergii [42], Alcea rosea L [43], and Atriplex halimus [44].…”

“…A single fiber tensile test proved that the fibers have the mean tensile strength, Young's modulus, and elongation at break of fiber 90.6 MPa, 1.46 GPa, and 6.45%. In addition, the fibers are thermally stable up to 456.98°C with thermogravimetric analysis [12]. Wirawan et al investigated the physicochemical properties of Hibiscus Tiliaceus fiber.…”

The main aim of this study is to identify a new sustainable plant-based fiber extracted from the reddish shell bean plant to investigate its usage in polymer matrix composites. Natural reddish shell bean fiber was extracted from vegetable shells with a biological degradation method. To determine the fiber characteristic properties, physical, chemical, and instrumental tests were performed on reddish shell bean fiber. The surface of the sample was determined with a scanning electron microscope, and it shows that the fiber has a rough surface along its length. In addition, an image processing approach was devised and implemented to determine the average fiber diameter of the reddish shell bean fiber. The elemental composition of fiber was obtained as 50.67 wt.% oxygen, 47.89 wt.% carbon, and 1.52 wt.% calcium with an energy disperse X-ray analysis device. In addition, fiber diameter was predicted as 785.87 μm with the image processing technique. The fiber density was measured as 1080 kg/m3. The crystallinity index of reddish shell bean fiber was calculated as 57%, and the fiber stables up to 328.23°C. The ultimate tensile strength of reddish shell bean fiber was obtained as 111 MPa. The elongation at break and estimated values of Young’s modulus of reddish shell bean fiber are 1.83% and 6.11 GPa, respectively. According to the results, reddish shell bean fiber can be utilized as reinforcement in polymer matrix composites.

Plant derived natural fibers have been widely investigated as alternatives to synthetic fibers in reinforcing polymers. Researchers over the years have explored many plant fibers using different extraction processes to study their physical, chemical, and mechanical properties. In this context, the present study relates to the extraction, characterization, and optimization of Typha angustata L. stem fibers. For this purpose, desirability functions and response surface methodology were applied to simultaneously optimize the diameter (D), linear density (LD); yield (Y), lignin fraction (L), and tenacity (T) of Typha stem fibers. Typha stems have been subjected to both alkali (NaOH) and enzymatic (pectinex ultra-SPL) treatments. Three levels of process variables including enzyme concentration (10, 15, and 20 ml/L) and treatment duration (10, 15, and 20 days) were used to design the experiments according to the factorial design. Experimental results were examined by analysis of variance and fitted to second order polynomial model using multiple regression analysis. The Derringer's desirability function released that the values of process variables generating optimized diameter, linear density, yield, lignin ratio and tenacity are 20 ml/L and 20 days for concentration of pectinex ultra-SPL enzyme and treatment duration, respectively. Confirmation was performed and high degree of correlation was found between the experimental and statistical values. Moreover, the morphological structure has been investigated by the scanning electron microscope, showing a crenelated structure of ultimate fiber bundles of cellulose composing the Typha fiber. Compared to Typha stem non-treated fibers (TSNTF), Typha stem combined treated fibers (TSCTF), brings to improve mechanical properties. This change in mechanical properties is affected by modifying the fiber structure showing alpha cellulose of (66.86%) and lignin ratio of (10.83%) with a crystallinity index of (58.47%).
