YUSRINA MAT DAUD, KAMARUDIN HUSSIN, AZLIN FAZLINA OSMAN, CHE MOHD RUZAIDI GHAZALI, MOHD MUSTAFA AL BAKRI ABDULLAH, ANDREI VICTOR SANDU DYNAMIC MECHANICAL PROPERTIES OF HYBRID LAYERED SILICATES/KAOLIN GEOPOLYMER FILLER IN EPOXY COMPOSITES Preparation epoxy based hybrid composites were involved kaolin geopolymer filler, organo-montmorillonite at 3phr by using high speed mechanical stirrer. A mechanical behaviour of neat epoxy, epoxy/organo-montmorillonite and its hybrid composites containing 1-8phr kaolin geopolymer filler was studied upon cyclic deformation (three-point flexion mode) as the temperature is varies. The analysis was determined by dynamic mechanical analysis (DMA) at frequency of 1.0Hz. The results then expressed in storage modulus (E’), loss modulus (E”) and damping factor (tan d) as function of temperature from 40 oC to 130oC. Overall results indicated that E’, E’’ and Tg increased considerably by incorporating optimum 1phr kaolin geopolymer in epoxy organo-montmorillonite hybrid composites.
