Novel natural plant fibers are being extensively investigated at this current scenario mainly owing to their significant properties over synthetic ones as renewable, biodegradable, and economical nature. With this outlook, the present study has tried to explore a novel plant fiber from Hibiscus canescens stem and analyzed its feasibility through various characterization methods. Water retting method was elected to extract fibers from the H. canescens stem. Chemical analysis was used to determine various chemical components as cellulose, hemicellulose, lignin, wax, moisture, and ash. The crystalline and amorphous conformation of H. canescens stem fibers (HCSF) were discovered using X-ray diffraction analysis. The chemical possessions are further validated through Fourier transform infrared spectroscopy analysis. After physico-chemical investigation, the feasible properties of HCSF were determined to be good crystallinity (48.78%), high cellulose content (68.46 wt.%), and relatively low density (1425 kg/m3). Moreover, the desired thermal stability (327°C) and tensile properties (394.9±14.42 MPa; 30.29±4.365 GPa) obtained through thermogravimetric analysis and tensile study demonstrated its suitability for high temperature fixed submissions. The exterior topographical study using SEM and AFM revealed that the surface is uneven with an average roughness of 7.200nm, which is another required feature for good fiber-matrix inter-bonding. Although, these intriguing features are satisfactory to ponder HCSF as a new promising material for composite fabrication in future. [ABSTRACT FROM AUTHOR] |
