Abstract
Epoxy resin (ER) composites reinforced with fly ash cenospheres (FACs) and short glass fibers (SGFs) were prepared. The tensile strength, flexural strength and modulus of ER composites achieved the maximum values when the content and ratio of the hybrids (FACs and SGFs) were 15 phr (per hundred of resin) and 2:1 (FACs: SGFs = 2:1), respectively, due to the uniform dispersion and better adhesion of hybrids to epoxy matrix. ER composite coatings were produced on the steel substrate which was pretreated to improve the adhesion of the coating to substrate. ER composite coatings exhibited high adhesion strength to the steel substrate when the substrate was polished with 150 mesh sandpaper, and the adhesion strength was further improved when the substrate was pre-coated with 10 wt.% resin acetone solution. In addition, the relationship between the erosion rate of ER composite coatings and the content and ratio of hybrids was studied. ER composite coatings exhibited the highest erosion resistance when the content and ratio of the hybrids were 20 phr and 1:1, respectively. The hybrids could effectively resist the cutting action of abrasives. The erosion rate of the ER composite coatings increased almost linearly with the increase of the erosion time.
