Effect of Particle Shape on Thermal Conductivity of Copper Reinforced Polymer Composites
Category: Transient Plane Source
Abstract: In this article, researchers studied the effect of particle shape on the thermal conductivity of copper reinforced polymer composites, using the Hot Disk method. Short-fiber shaped polyamide composites with filler content ranging from 0 to 30 % were measured, alongside of polyamides containing 0 to 60 % filler, shaped as spheres and plates. When the filler content is low, particles are not interacting with each other, and therefore the thermal conductivity is low. As the filler percentage increases to 10%, an immediate increase in thermal conductivity is seen. Overall, this experiment highlights the importance of particle shape, size and quantity, on the thermal conductivity of polyamide composites.
