Investigating novel AA5051/SiO2 nanocomposite with monolithic AA5051 for improving compressive strength.

This project aims to find the compressive strength of the recycled AA5051 alloy with and without reinforcing novel SiO2 using the stir casting method. Materials and Methods: The reinforcing particles used were novel silicon dioxide with a particle size of less than 50 nm, and the matrix materials used were recycled AA5051 alloys. To achieve consistent reinforcement distribution in matrix materials, it was casted using a stir cast method at a melting temperature of 720°C and a stirring speed of 500 rpm. Two types of samples were prepared using recycled AA5051 alloy (Control Group 1), Silicon dioxide reinforced AA5051 alloy nanocomposite (Experiment Group). Each group had a sample size of 20, with a pre-test power of 80%, a beta of 0.05 %, and a CL of 95%. The compressive strength of the novel silicon dioxide reinforced recycled AA5051 alloy was analyzed and compared with the control group material by using SPSS-V26 software. It was noted and observed that the significance of synthesized nanocomposites p=0.000 (2-tailed) was attained, which is lower than (p<0.05). This indicates that there is a statistical significance obtained between the control and experimental groups. Within the limitations of present study, it was found that there was an upgrade in the compressive strength of novel silicon dioxide reinforced recycled AA5051 alloy composites improved by 69.9% within the study's limitations.
