摘要
In the current study,the effect of flyash(FA)on the physic-mechanical,electrical,thermal and morphological behavior of nylon-66(PA)was inves-tigated.PA/FA composites were prepared by melt mixing via twin screw ex-truder,with varying weight percent(5 wt%,10 wt%,15 wt%and 20 wt%)of flyash.The results of composites were optimized and compared with vir-gin nylon-66.Mechanical and electrical properties of composites improved up to 10 wt%of FA loading without compromising the properties.The fly-ash filled nylon-66 composites showed a low abrasive wear rate.Increase the heat distortion temperature of composites with an increase in weight percent of flyash while opposing the melt flow rate.Flyash filler enhances the stiffness of plastics but significantly reduces the impact properties.Dis-persion of flyash was examined by impact fracture surface of composites using a scanning electron microscope.
