Abstract (Summary)

Thermally conductive composites have the potential to improve the performance of a wearable cooling garment which cools the wearer using flexible tubing circulating water as a heat exchanger. A review of the state of the art for personal cooling garments is performed along with the material factors which govern thermal conductivity. An examination of the design factors which determine the performance of such a garment is done, then a study is performed to examine the effect of processing variables in tubing extrusion on the performance of extruded tubing as well as material effects.

Filler behavior is also studied. The filler concentration within a thermally conductive composite is varied to determine the impact on thermal conductivity within a bi-material filler system. Finally, a review of filler migration within flow channels and the impact on thermal conductivity is presented, with experimentation performed to understand filler migration in a molded system.
