This paper is focused on the study of the structural, morphological, mechanical and microhardness studies on Fly ash reinforced PMMA composites. Fly ash reinforced PMMA composites have been prepared with the sol-gel method. Fourier transformed infrared (FT-IR) spectroscopy, X-ray diffraction, microhardness and atomic force microscopy (AFM) studies have been done on prepared composite. The AFM images confirm the presence of fly ash particles in nanophase within the PMMA matrix. The crystalline size of the in situ generated nanoparticles was investigated with X-ray diffraction technique and it is found that the crystallinity index increases with increasing the concentration of the fly ash. The structural characterization has been done with FT-IR spectroscopy. The FT-IR spectra of pure PMMA and fly ash based composites has been observed and analyzed. The Vickers microhardness indentation technique has been employed to detect the effect of reinforcement of fly ash in the PMMA matrix. Significant changes were observed in the various properties of the fly ash reinforced PMMA composites.
