摘要

The main objective of the present analysis is to investigate the effect of incorporating silane-treated Helianthus annuus waste derived cellulose into sugarcane leaf fiber-reinforced vinyl ester composites. Both the fiber and filler materials were effectively surface treated using 3-aminopropyltrimethoxysilant. The composites were prepared and their interlaminar shear strength (ILSS), wear resistance, water absorption, and flammability properties were evaluated in accordance with ASTM standards. The test results revealed that silane treatment significantly influenced the overall performance of the composites. Among the tested specimens, the BSC5 composite, which was treated with silane and reinforced with 1 vol% cellulose, exhibited the highest shear strength of 45.4 MPa. In addition, the BSC6 composite, containing 3 vol% silane-treated filler, demonstrated superior wear performance, with the lowest specific wear rate of 0.025 mm³/Nm and a coefficient of friction (COF) of 0.15, indicating excellent wear resistance. Furthermore, the BSC6 composite also showed the slowest flame propagation rate of 9.35 mm/min, reflecting enhanced flame retardancy. In contrast, the untreated composite with 3 vol% filler (BSC3) exhibited the highest water absorption rate of 6.3%, primarily due to the hydrophilic nature of the untreated natural fibers.
