Effect of Grafted Silane on Fly Ash Pha Lai - Vietnam to Properties of Polymer Composite Materials Based on Bisphenol A Type Epoxy Resin

Recently, there has been much research on fly ash and its use as a filler in polymer composite materials. However, interfacial adhesion of fly ash with polymer matrix is weak. So, fly ash must be treated to improve interfacial adhesion. This paper reports effect of surface treatments of fly ash particles to mechanical, thermal properties and structure of polymer composites based on DER 331 epoxy resin matrix. The fly ash was treated by silane coupling agent GF 80 and GF 82. The results showed that the mechanical properties of silane GF 80 and GF 82 treated fly ash epoxy resin composites were higher than that of untreated fly ash epoxy resin composites. Specially at FASGF80, tensile strength, flexural strength, compressive strength and impact strength was maximum tensile strength 42.3 MPa increase 21.74 compressive strength 164 MPa increase 18.29 flexural strength 77.8 increase 6.4 and impact strength 7.2 KJ m2 increase 20.83 compare with untreated fly ash composites .
