Thermal diffusivity measurements on composite porosity samples
Abstract
A phase lag technique is used to make quantitative measurements of diffusivity in composite porosity samples. Changes in through-ply diffusivity in a graphite composite due to varying porosity levels are examined. The relationship between the amount of porosity and the change in diffusivity is analyzed using an electrical analog for modeling heat flow in the composite.
