“…It was found to have a higher tensile strength value than Chrysanthemum morifolium Napier grass, Veldt-grape stem fiber, Hierochloe Odarata and Glycyrrhiza glabra fibers, shown in Table 2 , and a lower value than Bagasse fiber. In addition, the tensile modulus value was low due to the high lignin ratio, which is one of the characteristic features of stem fibers, but the elongation value was higher than the other fibers except for Oil Palm fiber [ 37 , 44 , 58 , 66 , 67 ].…”

Natural fibers extracted from plants are preferred as an alternative to synthetic products. The main reasons for this preference are their affordable cost, light weight and good mechanical properties. However, finding new natural raw materials is challenging due to growth limitations in different geographical areas. Platanus orientalis L. (Eastern plane tree) is a tree with abundant fruits that can grow in many regions of the world. The aim of this study was to determine the mechanical (tensile strength, tensile modulus, elongation), physical (density, fiber diameter) and chemical (cellulose, hemicellulose and lignin) properties of Platanus orientalis L. fruit’s stem by fiber extraction from the stems of the tree. It was determined that the extracted fiber had good mechanical properties and cellulose content of 42.03%. As a result of thermogravimetric analysis, it was determined that the plane tree fruit’s stem fiber had thermal resistance of up to 299 °C. The tensile strength value was 157.76 MPa, the tensile modulus value was 1.39 GPa and the elongation value was 22.01%. It was determined that it is suitable for use in fiber reinforcement in thermoplastic-based composites at temperatures below 299 °C. According to the results obtained by the mechanical, chemical and physical analysis of Platanus orientalis L. fruit’s stem fiber (PoLfs), it could be recommended as a suitable alternative as a reinforcing fiber in thermoplastic and thermoset composites.

“…For five minutes, the fibers were ball-milled at 800 rpm. The powdered stem fibers were dried in an oven at 100 degrees Celsius for four hours to remove excess moisture, which was probably present during both decomposition and washing [ 37 ]. Post-dried stem fibers, free of excess moisture, were used for chemical composition analysis.…”

“…NRL fiber realized its first degradation between 25–100 °C with an 8.6% weight loss thanks to water hydrolysis. Also, its first degradation with the effect of heat is observed at 287.59 °C temperature, at which cellulose molecules begin to degrade (T onset ) [ 77 , 78 , 79 , 80 ]. NRL fiber has a higher T onset temperature and thermal stability than kenaf (219 °C), hemp (205 °C), jute (205 °C), bamboo (214), and bagasse (222) bast fibers [ 81 ].…”

Nicotiana rustica L. (NRL) is a type of tobacco plant, and its stalk waste is a potential lignocellulosic source for obtaining cellulose fibers freely available in nature. However, they are left in fields after harvesting, and this study provides a green and sustainable method to reuse tobacco waste. Fiber was obtained by retting the plant stalks in water and decomposing them naturally in three weeks. NRL fiber was characterized by comparing it with known bast fibers, and tests were applied to examine its physical, chemical, mechanical, morphological, and thermal properties. With its high cellulose content (56.6 wt%), NRL fiber had a high tensile strength (113.4 MPa) and a good crystallinity index (70%) that helped it to bond with other fibers in the composite matrix. Furthermore, the fiber is an environmentally friendly alternative to synthetic fibers with a diameter of 36.88 μm and low density (1.5 g/cm3). The NRL fiber was found to have a semi-crystalline structure and large crystalline size, which makes it hydrophobic. The thermal gravimetric analysis showed that it can be durable (353.9 °C) in higher temperatures than the polymerization temperature. As a result, it can be concluded that NRL fiber has the potential to be used as a reinforcement in polymer composites, technical textiles, and agricultural applications.

In the present research, the usability of cellulosic-based fibers obtained from the Sorghum bicolor plant stem as reinforcing fibers in composites and textiles was investigated. The fibers were obtained from a Sorghum bicolor plant growing wild in the Adana region in the South of Turkey. Density, chemical structure analysis, FTIR, XRD, TGA, XPS SEM, and single fiber tensile tests characterized Sorghum bicolor fiber (SBF). SBF contains cellulose (73.6%), hemicellulose (13.3%), and lignin (12.1%). The oxygen/carbon ratio of 0.43 found as a result of XPS analysis indicates that fibers have a hydrophilic character. SBF has a 59.34% crystallinity index, 284.6 MPa tensile strength, 4.71% GPa tensile modulus, and 21.44% elongation at break. The maximum degradation temperature of the fibers was determined as 364.22 °C. Sorghum bicolor fiber, through detailed characterization, emerges as potential promising reinforcement for the composite industry with relatively good strength and high cellulose content for the textile industry.
