Abstract

Natural fiber-reinforced bio-epoxy composites have become promising sustainable alternatives to conventional synthetic-fiber petroleum-based materials, but are often limited by low fiber-matrix interfacial bonding, low thermal stability, and high moisture absorption which limit their application in structural applications. These issues are discussed in this work, by carrying out a systematic investigation of the synergistic effects of the hybridization of nano-silica particles with alkali-treated hemp fibers in a bio-epoxy matrix the composites comprising 05 wt.% nano-silica were fabricated by resorting to resin transfer molding with vacuum assistance. Mechanical tests indicated that huge improvements had been made with the 5 wt.% nano-silica variant achieving tensile strength of 119.8 MPa (74 % improvement), flexural strength of 148.7 MPa (61 % improvement), impact strength of 12.3 kJ/m2 (98 % improvement), and hardness of 97.8 Shore D (25 percentage improvement) versus the neat bio-epoxy base. Thermal treatment revealed that the temperature of the onset degradation rose by a factor of 66 o C to 358 o C and 22.4-percent weight of char, respectively, after 24 h immersion. This is attributed to enhanced interfacial adhesion and correct crack deflection as well as the formation of tortuous diffusion pathways that is precipitated by the uniformly dispersed nano-silica. The resultant hybrid composites offer one of the avenues through which lightweight, high-performance and environmentally friendly composites can be developed and applied in lightweight, high-performance and environmental-friendly automotive, marine and aerospace structural components.

Keywords: Hemp fiber composites, nano-silica hybrid reinforcement, bio-epoxy matrix, synergistic mechanical improvement, sustainable moisture resistant material
