Physical and thermal characterization of natural fibre extracted from Caryota urens spadix fibre

Abstract

In this study, comprehensive characterization of <em>Caryota urens</em> spadix fibre has been done to examine its morphological, physical, mechanical, chemical and thermal properties. High cellulose content of the fibre (42.1 wt%) provides better tensile strength (1970-6330 MPa) and ensures better bonding with the matrix. Moreover, the low density of the fibre (0.78 g·cm⁻³) makes it alternative for hazardous synthetic fibres. The lower crystal size structure tends to absorb more water than the higher crystal size structure. The thermogravimetric analysis confirms its stability up to 270°C, which is higher than the polymerization temperature. The results confirm the potential of <em>Caryota urens</em> spadix fibres as reinforcement in bio-reinforced polymer composites for automotive and structural applications.
