Structural, morphological and micromechanical studies on fly ash reinforced PMMA composites

Abstract

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.

Effect of Particle Size and Concentration of Fly Ash on Properties of Polytrimethylene Terepthalate

“…It is observed that fly ash with smaller particles showed higher value of tensile strength. The percentage elongation at break also decreases [10] on addition on filler as shown in Fig. 2.…”

“…[6,7] In this investigation we studied the effect of fly ash with three varying particle sizes and concentration on the properties of PTT. Recently many investigators studied the effect of fly ash on the properties of thermoplastics and thermosets [8][9][10][11][12][13][14][15]. Fly ash is the finely divided mineral residue resulting from the burning of pulverised coal in thermal power stations.…”

Improved mechanical and moisture resistance property of in situ polymerized transparent PMMA/Cellulose composites

“…It is clearly evident from Fig. 7c that PMMA film has smooth surface which indicates the presence of planarized macromolecular chains [20]. Incorporation of MACNF into PMMA matrix helped in the development of triangular pattern, that is, within PMMA matrix (Fig.…”
