摘要

This investigation examines the effect of ceramic fillers on the structural and functional performance of sisal fiber-reinforced epoxy matrix composites, with an emphasis on their applicability in sustainable material systems. A multi-faceted characterization approach was employed, encompassing ultraviolet (UV) absorption spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, mechanical property evaluation, and scanning electron microscopy (SEM). Progressive enhancement in UV shielding capability with increasing ceramic filler content, indicative of improved resistance to photodegradation and prolonged lifespan. The formation of strong interfacial interactions between hydroxyl groups of the sisal fibers, ceramic filler surfaces, and the epoxy matrix, confirming effective chemical compatibility and interfacial adhesion. Testing showed marked improvements in tensile, flexural strength, and impact resistance. Optimal mechanical performance observed at specific filler loadings, attributed to improved stress transfer and energy dissipation mechanisms. SEM corroborated these findings, revealing uniform filler dispersion, minimal agglomeration, and enhanced fiber-matrix interfacial bonding, contributing to reduced micro void formation and improved fracture resistance.
