Using the materials thermal conductivity (k) the amount of thermal energy transferred through a material can be determined. However, this task becomes challenging when a material is non-homogeneous & non-isotropic (see below).
ESI has developed methods and facilities to measure non-homogeneous materials thermal conductivity values using up to 3” x 3” x 0.5” material samples to fully capture the thermal conductivity variation within the material.
The above images provide a sense of the visible
variations in the material surface.
