The Effects of Different Eggshell-Silicone Biocomposite Under Uniaxial Tensile Loading

Abstract

Chicken eggshells are a major waste product in almost every country due to their extensive use as eggs are used in millions of household and industries. As a result, managing these waste products has become challenging as they not only occupy space in landfills but also release greenhouse gasses decomposition. In recent years efforts have been made to develop new materials using sustainable sources such as biocomposites. This study aims to fabricate eggshell silicone biocomposites and examine its behaviour under uniaxial tensile loading. This study consisted of two phases: fabrication of eggshell silicone biocomposite and mechanical testing under uniaxial tensile with 50 kN. During the first phase; eggshells were washed, sterilized, and crushed into powder form. Subsequently, they were mixed with silicone at different eggshell powder content (e.g., 5, 10 and 15 wt.%). In the second phase, the specimens underwent uniaxial tensile strength. The ultimate tensile strength increases from 0.43772 MPa to 0.47331 MPa from 5 wt.% to 10 wt.%. However, it decreases to 0.42535 MPa when reaches 15 wt.% eggshell weight. This study is in line with previous study that uses Arengga Pinnata silicone biocomposite.
