Studies on Dynamic Mechanical Analysis and Morphology of Carbon Soot Filled Un saturated Polyester Graded Composites
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 3
Abstract
Dynamic mechanical behaviour of carbon soot filled polyester graded composites was determined with reference to carbon soot concentration present at different positions of the graded composites. At lower temperatures ,E’ values are maximum for unsaturated polyester resin whereas above Tg E’ values of graded composites are higher than the pure polyester resin . The loss modulus peaks values decreased on increasing the carbon soot concentration .Tg values increased with increase in sootconcentration . Apparent activation energy of the relaxation process of different composites were analysed.
