Characterization of cellulose fiber extracted from stems of Myriostachya wightiana (MW) plants: a viable reinforcement for polymer composite

摘要: There is an urgent need to investigate more eco-friendly fibres due to the high cost of traditional cellulosic fibres. Eco-friendly MW fibre was extracted and characterised as a potential replacement for risky artificial fibre. Physicochemical, XRD, FTIR, SEM, thermal analysis, and Weibull distribution methods were used to study MW fibre as a biocomposite reinforcement. The density, tensile strength, Young's modulus, strain at failure, and micro-fibril angle of MW fibre with an average diameter of 102.278 μm were found to be 1372–1510 kg/m3, 46.554 MPa, 2.442 GPa, 8–9%, and 22 ± 1°, respectively. The predicted Young's modulus and strength of the fibre showed a good match with the experimental data in the Weibull distribution analysis. In addition, FTIR verified the presence of cellulose (O = H), hemicellulose (C = O), lignin (C = C), and wax (CC) in the fibre. XRD study reveals CI and CS of 58.07% and 2.86 …
