Investigation and chemical processing effect of sisal fiber epoxy composite characteristic enhancement with nano-SiC via injection mold.

Environmentally, biodegradable natural fiber plays a vital role in polymer composite fabrication due to its cost-effectiveness, reduced specific weight, and specific stiffness behavior. Besides, the research gap spotted on processing challenges, including lack of adhesive behavior, results in lower mechanical behavior of composite. The main objective of the present research is synthesizing of epoxy-based poly composite enclosures with 5% sodium hydroxide processed natural sisal fiber (SF) as 20 vol% via thermally assisted injection mold route, which functional behavior is enriched by the accumulations of 3, 6, and 9 vol% of nanosilicon carbide particles (SiC). The impacts of processing accumulations of nano-SiC/SF on metallurgical (scanning electron microscope (SEM)) and mechanical functional properties including tensile strength, elongation percentage, flexural strength, and fracture toughness of epoxy/NaOH-treated natural SF and its composites embedded with nano-SiC are studied. The novel research is recorded with the exposure of SEM metallurgical analysis results, and better SF distribution along the epoxy matrix with a coarse grain of nano-SiC is identified on hybrid compositions. Amid the various compositions mentioned above, the epoxy/20 vol% SF (NaOH treated)/6 vol% nano-SiC composite has superior tensile strength, better elongation percentage, improved flexural strength, and good fracture toughness of 54 ± 1.5 MPa, 18 ± 1%, 76 ± 2 MPa, and 1.61 ± 0.04 MPam^0.5, which is greater than the value of epoxy/20 vol% SF (NaOH treated) composite sample.
