Investigations of Nanoparticles (Al₂O₃‐SiO₂) Addition on the Mechanical Properties of Blended Matrix Polymer Composite

Abstract

The manufacture and investigation of the characteristics of nanocomposites with nanoparticles are made by the sol-gel technique. It comprises two substances (aluminium oxide-silicon oxide), as well as the influence of such particles on the mechanical characteristics of a polymeric matrix is described in this study. Tensile, bending, and hardness tests were utilized to assess the mechanical characteristics of the hybrid material. The evaluation results of composite nanoparticles revealed a clear dispersion of chemical components among aluminium oxide and calcium oxide, softness in particulate matter during crystallization at high and low temperatures, the initiation of various nanostructures forms, and distinct stages of an alumina particle. When compared to a polymeric mix without nanoparticle inclusion, mechanical behaviour tests demonstrated a considerable improvement in the mechanical capabilities of the nanocomposites, notably at 2%. Mechanical parameters such as tensile strength are 61.36 MPa, flexural strength is 74.25 MPa, and hardness is 83.27 D at 2.5 wt% at 600°C heat treatment conditions. Under 900°C heat treatment conditions, tensile properties of 54.12 MPa at 1 wt. percent, flexural properties of 79.21 MPa at 2 wt. percent, and shore hardness of 81.21 D at 2.5 wt. percent of nanoparticles were measured.
