Experimental investigation of mechanical and erosion behavior of eggshell nanoparticulate epoxy biocomposite

Abstract

In the present work, the mechanical and the tribological properties of eggshell nanoparticulate epoxy biocomposite were studied. The nanoparticles of eggshell were synthesized by planetary ball milling technique. Synthesized eggshell nanoparticulate were characterized with the aid of Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-ray diffraction analysis, and Fourier Transform Infrared (FTIR) Spectroscopy. Fabrication of eggshell nanoparticulate epoxy biocomposite was done by hand lay-up technique with different weight percentages (1 wt%, 2 wt%, 3 wt%, 4 wt%) of eggshell nanoparticles. To examine the solid particle erosion behavior of eggshell nanoparticulate epoxy biocomposite, four different impact angles (30°, 45°, 60°, 90°) and three different velocities (101 m s−1, 119 m s−1, 148 m s−1) were chosen. The effect of eggshell nanoparticles incorporation on the tensile properties, hardness, and the flexural properties was also investigated. The fractured surfaces of the tensile test, flexural test, and erosion test samples were examined with a SEM for morphological analysis. It was found that the eggshell nanoparticulate addition has a fruitful effect on tensile and flexural strength. The maximum tensile strength was found for 2 wt% nanoparticles addition, while the maximum flexural strength was found for 3 wt% of nanoparticles addition. The sand erosion study established a maximum wear rate at 60° of impact angle. The maximum erosion resistance was found in 2 wt% of eggshell nanoparticulate concentration.

Biomass-Derived Anion-Anchoring Nano-CaCO3Coating for Regulating Ion Transport on Li Metal Surface

“…In the Fourier transform infrared (FTIR) spectrum (Figure S3), the main peaks were attributed to CaCO 3 as well as the amide bands for the eggshell membrane, , suggesting the presence of abundant polar groups in NC. From the X-ray diffraction (XRD) pattern, the diffraction peaks of NC match well with those of standard calcite crystals, confirming the high degree of crystallinity and purity of the sample (Figure S4).…”

Investigation on the Effects of Uncarbonised, Carbonised and Hybrid Eggshell Filler Addition on the Mechanical Properties of Glass Fibre/Polyester Composites

“…Similar results have been documented by other researchersDin which the authors have attributed the crack arrest to the homogenous distribution of eggshell filler particles. [33] Interfacial bonding of eggshell filler and polyester resin can also be seen in the SEM images. Interfacial bonding of filler and matrix plays a vital role in the strengthening of material.…”
