Comparative Study of Mechanical Properties of Coir–jute Fiber-reinforced Composites Enhanced by SiC Nanoparticles
J. Environ. Nanotechnol., Volume 15, No 1 (March 2026) pp. 225-231
Abstract
Natural fiber composites are increasingly explored as sustainable alternatives to synthetic materials, but their limited mechanical strength and poor moisture resistance often restrict their applications. This study investigates the mechanical characteristics of hybrid coir–jute fiber-reinforced composites incorporating silicon carbide (SiC) nanoparticles, fabricated using the manual lay-up technique, to address these challenges. Water absorption behavior was evaluated alongside three-point bending, hardness, and impact resistance tests to determine performance improvements. The results showed that incorporating SiC nanoparticles significantly enhanced the properties of the composites. In particular, composites containing 8 wt.% SiC nanoparticles exhibited the lowest water absorption (1.7%) and the highest hardness value (104 HV). They also achieved superior flexural strength (82 MPa), modulus of elasticity (4.38 GPa), and impact energy absorption (19 J). These outcomes demonstrate that SiC nanoparticle reinforcement can effectively improve the durability, strength, and reliability of coir–jute fiber-reinforced composites, highlighting their potential as sustainable alternatives to conventional synthetic fiber composites in structural and industrial applications.
