| dc.description.abstract | This research was conducted to examine the experimental and numerical heat transfer coefficient of fiber-glass/talc-filled epoxy composites. And then, the numerical results were validated with the experimental results. Fiber-glass/talc-filled epoxy composites were prepared with different mixing ratios, cured at room temperature for 24 hours and then post-cured at varying temperatures (50˚C, 75˚C, 100˚C, 125˚C, and 150˚C) while keeping the curing time constant. Models of the composites were generated in ANSYS using the thermal properties of the composites with different mixing ratios and curing time, the properties of the heater were also inputted and the air was the convective fluid. The heat was applied to the composites and the inner and outer wall temperatures were taken and used to determine the heat transfer coefficient of the composites. From the results obtained numerically, it was observed that increase in post-curing temperature led to an increase in composites with higher talc particle size (106μm) while the heat transfer coefficient of the composites with lower talc particle size (75μm) exhibited a lower heat transfer coefficient. In order to validate the numerical model, an experiment of composites with a lower heat transfer coefficient than epoxy post-cured at 100˚C was carried out following all the steps taken in the numerical simulation, and the results were compared. | en_US |
