joining thermal management graphite composites

Thermal Conduction in Graphite Flake

The effective thermal properties of these composites exhibit high variability that depend on the topological arrangements and the morphological characteristics of the filler particles. In order to tailor the thermal conduction within these composites for their use as an efficient heat dissipation material, careful control of the microstructural arrangement of the filler material is required.
