Due to increasing environmental concerns, there is growing interest in sustainable natural fiber-based hybrid composites. However, these materials face significant challenges across various fields and applications. This study aims to enhance jute-palmyra fiber-reinforced epoxy hybrid composites by incorporating nano-silica particles. The research investigates the improvement of physical, mechanical, and tribological characteristics of the composites with functionalized silica nanoparticle concentrations ranging from 0 % to 4 wt.%. Results show that increasing SiO

content enhances the composite’s density. Specifically, the composite with 3 wt.% SiO

exhibits the highest flexural strength (71.20 MPa), while 2 wt.% SiO
2
demonstrates superior tensile strength (55.52 MPa), impact resistance (4.02 J), and hardness (36 HV). Dry sliding wear tests using an L16 orthogonal array design reveal that hybrid nanocomposites with 2 wt.% SiO

display superior wear resistance under specified conditions. These findings underscore the significant performance advantages of SiO

-natural fiber hybrid composites, highlighting their potential in sustainable material applications.
