An in-depth investigation into the utilization of nettle fiber-reinforced epoxy composites with embedded MgO nanoparticles

Abstract

The present work thoroughly examines the possible utilization of nettle fiber reinforced MgO nanoparticles filled epoxy composite as a viable and environmentally friendly alternative for engineering applications. The experimental investigations included various mechanical, structural, and thermal examinations, incorporating tests such as tensile, flexural, Izod impact, and Shore D hardness tests. Also, the composite was analyzed using advanced characterization techniques to determine its morphological and chemical properties. The findings demonstrated improved mechanical properties are tensile strength (36.23 MPa) and flexural strength (40.13 MPa), Izod impact strength (15 kJ/m2), and Shore D hardness (64) indicating the potential of the composite material for use in load-bearing applications. Scanning Electron Microscopic images elucidated a uniform dispersion of MgO nanoparticles, while elemental analysis, X-ray Diffraction, and Fourier Transform Infrared Spectroscopy confirmed their successful integration within the epoxy matrix. Thermal evaluations recorded significant improvements in heat deflection temperature and thermal conductivity, accompanied by a reduced coefficient of linear thermal expansion, indicating the composite’s ability to withstand and dissipate heat efficiently. Also, it contains the antibacterial activity against the Pseudomonas aeruginosa and Staphylococcus aureus. Conclusively, the nettle fiber reinforced MgO nanoparticles-filled epoxy composite demonstrates significant value as an environmentally sustainable and mechanically robust material for various engineering and biomedical applications.
