This analysis compares mechanical and thermal properties of nano-SiO2-reinforced epoxy composites with coir fiber, suggesting improved biodegradability and strength.
Comprehensive analysis of nano-SiO2-reinforced epoxy composites and compared them with commonly used coir fabric. For both static and dynamic applications, coir fabric composites were considered as suitable material due to their strength and biodegradability. In this research, 15 nm SiO2 nano powder was used as a filler. Several composite laminates with different filler concentrations of 2%, 3%, and 5% SiO2 by weight of the epoxy resin were fabricated using hand lay-up method (LY556). Various testing methods, including tensile testing, impact testing, wear testing, moisture absorption testing, and thermogravimetric analysis (TGA), were employed to evaluate the properties of the final composite. The results indicated that the mechanical and thermal characteristics of the produced composite were significantly influenced by the filler material.
