Abstract

<jats:p>Rice husk was used to produce silica particles, which were then used toreinforce the polymer matrix. The synthesized SiO2 particles werecharacterized using X-ray diffraction, Fourier transforms infraredspectroscopy (FTIR) and scanning electron microscopy with EDS. In a PMMAmatrix, prepared SiO2 particles in amounts of 1, 3, and 5 wt.% were used asreinforcing agents. The goal of this research was to see if SiO2 particleshad any effect on the mechanical properties of polymer composite materials.The morphology of the composites was examined using a field emissionscanning electron microscope (FE-SEM). Vickers microindentation hardness andimpact testing were used to determine the mechanical properties of theobtained composites. The indentation creep?s behavior of apolymethylmetacrylate (PMMA) composite material with varying amounts ofnanoparticles (SiO2) was investigated and analyzed.</jats:p>
