Abstract

Composites of diglycidyl ether of bisphenol A resin modified with Amine Contg. Silicone as matrix and fly ash and cenospheres as fillers have been examd. for their mech. and microstructural properties. The microstructural features of the composites in terms of free vol. size and content, and its influence on the mech. properties has been investigated. The results indicate that amine contg. silicones works as a good coupling agent between the filler and the resin. Composites with 5 phr fly ash and 30 phr cenospheres showed improved thermal stability as indicated by the increased Tg of the composites, possibly because of increased Si-O-Si linkages. The tensile strength of cenospheres-filled composites showed good improvement compared with that of the fly ash-filled composites. Low d. (0.6 g/cc) and higher silica content (60%) of cenospheres seems to be the reason for this observation, which is well corroborated by the free vol. data. POLYM.
