Effect of Micro balloon Content on Glass Transition Temperature of Unsaturated-based Polyester Syntactic Foam

In this study, unsaturated-based polyester synthetic foams containing various wt. % PMMA-based hollow micro-balloons were prepared. Mechanical properties of the foam samples were evaluated using dynamic mechanical analysis (DMA) in three point bending mode. The effects of microsphere content reinforcementon the damping coefficient and glass transition temperature, Tg, were studied. Tg values obtained from themeasurements were compared with the values from theory calculation. The synthetic foams prepared in this way revealed enhanced mechanical properties and appropriate true density
