Bachtrong P., Nguyenthanh L., Phamthi H., 2017, Effect of Fly Ash from Thermal Power Plant on the Dielectric Properties of Polymer Composites Materials based on Matrix Epoxy DER 331, Chemical Engineering Transactions, 56, 1207-1212.
Fly ash (FA) is a low cost, inorganic waste product obtained from thermal power plants. This waste product causes significant environmental problem but it possesses good mechanical properties due to the constituent phases contained in it i.e. silica and alumina. In this paper, epoxy resin matrix, a good insulating polymers, combined with FA was used to manufacture composite polymer materials. The effects of the compositions of fly ash witht and without treatment on the dielectric properties of polymer composite (PC) materials based on epoxy resin DER 331 were studied. The results show that the samples with modified fly ash using 2 % stearic acid and 2% silane GF80has significantly improved the insulating properties of the material compared to the non-modified composite samples.
