摘要

This study examines the mechanical, physical, water-absorption, elemental characteristics, thermogravimetric and Fourier-transform infrared spectroscopy analysis of epoxy composites reinforced with Areca husk fiber and included with Areca nut seed filler. Five distinct composites were fabricated using compression moulding techniques, maintaining a constant 70 wt% epoxy while varying the fiber/filler ratios from 30/0 to 20/10 wt%. Areca fibers were treated with 5% NaOH to enhance surface roughness and strengthen the fiber-matrix adhesion. The mechanical characteristics, including tensile, flexural, impact, interlaminar shear strength, and hardness were determined. The structure and components are examined by water absorption, thickness swelling, SEM, and EDAX analyses. The thermogravimetric analysis (TGA) was used to investigate the thermal characteristics of biodegradable hybrid composites. In addition, the FT-IR spectroscopy method was utilized to investigate the chemical formation of the novel bio composites. The composite containing 22.5% areca husk fiber and 7.5% areca nut seed filler (22.5AHF7.5AFI) exhibited superior performance, achieving a tensile strength of 72.58 MPa, a flexural strength of 63.92 MPa, an impact strength of 11.43 kJ/m², and compression strength of 34.78 MPa. The composite with 20% of areca husk fiber and 10% of areca seed filler has maximum hardness value of 78.17, and a low water absorption rate, thickness swelling of 2.02%. EDAX indicated the presence of carbon, oxygen, and other elements, signifying effective dispersion of the filler and optimal interaction with the matrix. The TGA results showed that hybrid composites of (22.5AHF7.5AFI) had the highest thermal stability. The presence of cellulose and hemicellulose are showed in the FTIR analysis. The findings indicate that hybrid composites derived from Areca fiber are suitable for application in the field of light weight automobile interior panels and packaging materials.
