“…The major crystalline peak ( I 002 ) occurred within a range of 21.96°–22.97° of the 2 θ values for each profile and the amorphous peak ( I am ) occurred within a range of 17.87°–19.06° of the 2 θ values for each profile. [ 53–55 ] It is quite clear from Figure 3 and Table 2 that the sodium carbonate and peroxide treatment of hemp fiber have increased the I C of the fiber. There is an enhancement of 1.79% and 5.23% in I C of ST and PT hemp fiber over UT fiber.…”

In this research work, the effects of sodium carbonate and hydrogen peroxide treatment of hemp fiber on the water absorption, mechanical, and tribological properties of hemp fiber reinforced epoxy composites (HFREC) were investigated. The change in surface roughness and fiber size after chemical treatment was confirmed by the scanning electron microscopy (SEM) images. Fourier transform infrared analysis confirmed the removal of hemicellulose and lignin content of the fiber after both the chemical treatment. X-ray diffraction analysis showed an increase in the crystallinity index of the chemically treated fiber.The experimental results also revealed that both sodium carbonate and peroxide modification have resulted in enhancement of water resistance and mechanical properties such as tensile strength and tensile modulus and reduction in impact properties of treated HFREC. Tribological test results revealed that the treated HFREC have improved wear and frictional properties in comparison with untreated HFREC. The best tribological and mechanical properties were exhibited by peroxide treated HFREC, which was also confirmed through the SEM images of worn and fractured surfaces of the composites.

“…It was clearly indicated that due to applied tensile force, the fiber breakage and the fiber pullout was occurred partially in the composites. This was due to a certain amount of hemicellulose, lignin, and wax and moisture contents are partially present on the fiber surface [38]. The Fig.…”

In this research work, the untreated and various concentrations of alkali treated continuous mulberry fibers were used as reinforcement in polyester matrix and its static and dynamic mechanical properties were investigated. The composites were fabricated using untreated, 5%, 10%, and 15% alkali treated mulberry fibers (ATMF) reinforced in polyester resin by compression molding technique. The result showed that the 10% alkali treated mulberry fiber composite (ATMFC) considerable increase in tensile, flexural, and impact properties compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The 15% alkali treated mulberry fiber composite showed decrease in water absorption property. The fractured surface morphology of composite samples was examined by Scanning Electron Microscopy (SEM). The Dynamic Mechanical Analysis (DMA) shows that the 10% alkali treated mulberry fiber composite enhanced storage and loss modulus compared to untreated, 5% and 15% alkali treated mulberry fiber composites. The weight loss of untreated, 5%, 10%, and 15% alkali treated composites were studied under varying temperature by Thermo Gravimetric Analysis (TGA) and Differential Thermo Gravimetric analysis (DTG).

“…[ 69 ] Although, lower ash content of EFLF validate that the fiber possess less amorphous fractions such as lignin and hemicellulose, making it a viable candidate for a wide variety of applications. [ 70 ] Likewise, lower moisture content is an essential feature that is required for its long‐term usage of fiber. EFLF has low moisture content (8.04%) than Ricinus communis (10.17%), Pergularia daemia (10%), Prosopis juliflora (9.48%), Flax (10%), Passiflora foetida (9.54%), (10.8), Cissus quadrangularis stem (6.6%), and Sisal (!1%).…”

The promising characteristic features of some natural plant fibers identified has driven many scientists/researchers to seek more plant fibers with good mechanical, thermal, tensile and surface properties. Plant fibers with such characteristics along with their renewable, degradable, eco‐friendly, cost‐effective nature could make them a probable competitor against synthetic ones, in many aspects. Since identification of novel plant fibers with superior quality is necessary at the moment in order to reduce the harmful effects of synthetic materials. Since the current study recognized a novel natural plant fiber from Echinochloa frumentacea and analyzed its efficiency for composite fabrication through various characterization practices. It was found from the physico‐chemical investigation that the fiber encloses with good crystallinity index (35.87%), cellulose content (60.31%) and relatively low density (896 ± 32.14 kg/m3). In fact, EFLF's has admirable thermal stability (330°C) and tensile strength (204.32 ± 14.25 MPa) designated its suitability for temperature varying environments. Conversely, the proposed fiber ensures good fiber‐matrix adhesion in spite of good surface roughness and decreased microfibrillar angle (9.27 ± 0.31°), noted by surface analysis. Hence, the current study recommends further utilization of EFLF as a reinforcing material with high specific qualities and low environmental effect, for composite manufacturing.
