Influence of Eggshell Nanoparticles and Effect of Alkalization on Characterization of Industrial Hemp Fibre Reinforced Epoxy Composites

Nowadays most of the researchers are focusing their research on pollution free environment, bio-degradable nature and balanced ecological aspect while fabricating the composite materials rather than mechanical strengths, costs, processing methodologies, etc. The objective of this experimental study is to analyze the influence of the bio-based eggshell nanoparticles on the thermal and morphological properties of alkali-treated hemp fibre reinforced epoxy composites. The composites were fabricated by hand lay-up process followed by compression molding technique and the properties of composites are analyzed by using thermo-gravimetric analysis, Fourier transform Infra-red spectroscopy, differential scanning calorimetry and X-ray diffraction techniques. The mechanical properties such as tensile, shear, flexural and impact strengths as well as water absorption characteristics of these composites are also investigated. The morphological characteristics were analyzed by scanning electron microscopy analysis. The results clearly showed that the incorporation of eggshell nanoparticles has significant influence on the thermal and morphological properties of alkali-treated hemp fibre composites.
