Evaluation of mechanical, thermal, and morphological properties of novel cellulosic bio-fiber from Licuala grandis peduncle for lightweight biocomposite applications

The composite industry is focusing on bio-waste as an alternative source of raw materials to address sustainability challenges in its procedures and goods. This study describes the characteristics of Licuala grandis tree peduncle fibers (LGPFs), a novel agro-waste that is segregated from the peduncle of the tree. Quantifiable information about LGPF, such as its tensile strength (232-273 MPa), Young's modulus (2.2-4.9 GPa), better crystallinity index (51%), and cellulose proportion (58.31 weight percent), is obtained owing to the thorough examination. Thermogravimetric (TGA/DTG) and differential scanning calorimetry (DSC) inquiries provide insight into the LGPF's thermal behavior and reveal that it will remain stable up to 236 degrees C. The analysis of Fourier transform infrared spectroscopy (FTIR) spectroscopy helps to validate the outcomes of chemical examination. Scanning electron microscope (SEM) analysis of the LGPF's surface roughness supported the idea of using it as reinforcement material in composites with polymer as matrix. LGPF-reinforced polymer composites can be used in structural applications, according to the experimental findings.
