Web7.18.1 Thermal Expansion Anisotropy. The CTE of C/C is anisotropic, being higher in the through-thickness direction than the fiber direction. This is expected, since the carbon fibers rather than the carbon matrix is responsible for the low CTE in the fiber direction. The CTE decreases with increasing heat treatment temperature. WebThermal conductivity is determined in line with DIN 52612. This measurement defines the quantity of heat passing through a given specimen thickness per unit of time. At 20 °C, Desmopan® has a thermal conductivity of 0.20 to 0.25 W/ (K m). At 80 °C, its thermal conductivity falls to 0.17 to 0.20 W/ (K m). Brand.
