“…Although fiber pullout was seen, the addition of nanofibers increased matrix bonding and enhanced the mechanical properties of the composite as 8%CQF/2%NCQF/PLA composite has a higher tensile strength of 65.68 MPa than the 10%CQF/ PLA composite. [194] The effect of acetylation on the surface of flax fiber and its composite with polypropylene was studied, and better results were obtained at 18% acetylation. The acetylation removed wax and cuticle from the fiber surface, enhanced the interfacial strength and surface free energy of the fiber-matrix.…”

Natural fiber‐reinforced polymer composites (NFPCs) have gained limelight in many applications during the recent years, owing to their availability, as well as superior mechanical characteristics, cost‐effectiveness, biodegradability, and lightweight. A comprehensive understanding of the manufacturing methods, proeprties and characteristics of natural fibers pave way for begetting a wide spectrum of applications for the NFPCs in automobile, aerospace, electronics, and other engineering fields. The current review article is about natural fiber‐reinforced composites, the commonly used fabrication methods, including fiber pre‐treatments, and numerous intermediate steps added to achieve improved bonding, processability of these composites, their properties and application prospects. Various state‐of‐the‐art methods like additive manufacturing, vaccum bag molding, and autoclave has also been discussed. The mechanical properties obtained through various fiber reinforcements in accordance with process parameters has a substantial impact in the industrial applications of NFPCs. The tribological applications of NFPCs are becoming increasingly important in order to deal with the mechanical and chemical wear and tear during their service life in contact applications. Flammability behavior and biodegradability assessment of NFPCs are important for high‐temperature and outdoor environmental applications of these materials. The review also includes a comprehensive discussion about the trending applications and future prospects for NFPCs.

“…Given the small size of electrospun nanofibers, no specific method is suitable for measuring them. Therefore, a single-fiber strength tensimeter is widely used to measure the mechanical properties of nanofiber membranes 27 . The tensile strength of materials can be measured by their physical quantities, such as the maximum tensile strength, the breaking force, the elongation at break, and the elastic modulus 50 .…”

The cellulose of carex meyeriana kunth (CMKC) was used as raw material, and the spinning solution was prepared by combining with polyacrylonitrile (PAN). The nano-cellulose fiber of carex meyeriana kunth (CMKN) was prepared by electrospinning. Used to remove methylene blue dye (MB) in aqueous solution. In the electrospinning experiment, the addition of CMKC was in the range of 5% ~ 25%, the feed rate of spinning parameters was set in the range of 0.2 ~ 1.0 mL/h, the distance from the needle tip to the collecting plate was in the range of 10 ~ 25 cm, and the voltage was changed in the range of 15 ~ 25 kV. The obtained CMKN was characterized by scanning electron microscope, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy. The MB removal rate was evaluated in the dye removal experiment, and the effects of CMKN on MB removal rate under the factors of CMKC dosage, temperature, shock time and MB initial concentration were discussed. The optimum process conditions were determined by response surface methodology. The results show that the prepared fibers are superfine fibers with nanometer diameter, and the spun nanofibers have smooth surface, high overall orientation and strong uniformity. The adsorption kinetics of prepared CMKN accords with quasi-second order model, and the adsorption isotherm accords with Langmuir model. The maximum dye removal rate of CMKN is 63.24%.

Carex meyeriana Kunth is a renewable cellulose resource with abundant reserves in nature and has a large research space, but its application is limited and still under development. Hence, Carex meyeriana Kunth is worth developing. Carex meyeriana Kunth's cellulose is abbreviated as CMKC. This study aims to produce cellulose nanofibers (CMKN) from CMKC by electrostatic spinning. The electrostatic spinning solution was prepared by mixing the self-made cellulose solution with 15% polyacrylonitrile, and a CMKN was obtained by electrostatic spinning. The influence of adding cellulose concentration, voltage, the receiving distance, and the pushing speed on the fiber surface morphology was considered. In the tests, the feed rate of the spinning parameters varied in the range of 0.2–1.0 mL/h, the distance from the tip to the acquisition board varied in the range of 10–25 cm, the voltage was 15–25 kV, and the relative humidity was 65%. The fibers were characterized by scanning electron microscopy, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy. The optimal process route was explored. At 21 kV, 20-cm receiving distance, and 0.5 mL/h pushing speed, the spun nanofibers have a smooth surface, a high overall orientation, strong uniformity, and fiber diameter. According to XRD, infrared spectroscopy, and the single-fiber tensile strength test, the crystallinity of cellulose decreases and the tensile strength increases after the transformation from cellulose to nanofiber. Through chemical and mechanical means, we effectively removed the non-cellulose components and increased the cellulose content. The cellulose in the nanofiber is type I. Response surface diagrams help to understand the interaction of these parameters. Langmuir adsorption isotherm is the best fitting model for MB removal by CMKN. The kinetic model is better explained using a pseudo-second-order model. It can be seen from the experiment that the best dye removal conditions are 30℃, MB solution concentration 40mg/L, shock time 90min, 15% cellulose nanofilm removal rate is 63.24%.
