The 2D-Anisotropy Module allows to measure thermal properties linked to the warmth transfer of anisotropic materials such as layered materials or fiber-reinforced plastics...

To measure anisotropic materials, the sensor is sandwiched between two pieces of the sample having flat surfaces. A continuous electric power is sent inside double spiral.

For the 2D-Anisotropy Module, the sent power is between 1 and 10 W. The manipulation time varies between 2.5 and 640 s and the sensor diameter is between 1 and 60 millimeters.

Of course, these parameters depend on the layer and nature of material. While measurement, pressure evolution inside the spiral is recorded. This pressure is proportional to the temperature evolution at the sensor surface.

During the experimentation, from temperature data and specific heat capacity valor (known in advance), thermal conductivity and axial and radial thermal diffusivity  of  anisotropic material are calculated.
