Extraction and Characterization of a New Natural Cellulosic Fiber from Bark of Ficus Carica Plant as Potential Reinforcement for Polymer Composites

Abstract

High specific strength and modulus of fiber-reinforced polymer composites tend to be the reason for replacing many metallic structures. Synthetic fiber (E-glass) becomes a risk for health and leads to cancer. Ficus Carica (FC) bark fiber undergoes comprehensive characterization analysis such as Thermal Gravimetric Analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Physical analysis and Chemical analysis. Bark of Ficus Carica plant is taken and the fibers are extracted. It is essential to study microstructure, chemical composition and mechanical properties of the fiber to utilize these lignocellulosic fibers as a reinforcement material in polymer composites. The results of this investigation are very encouraging for its applications to be used in industries for manufacturing fiber composites. FC Bark Fiber (FCBF) contains high cellulose content such as 63.17% and very little wax (0.42%). Good thermal stability of the fiber up to 225°C was produced from thermogravimetric analysis, which is well indicated within its polymerization process temperature. FCBF’s exhibit suitable properties that are to be used as natural reinforcement material.
