Thermal conductivity of carbon-phenolic 8-harness satin weave composites

In this paper, thermal conductivities of carbon-phenolic 8-harness satin weave composite were measured and predicted. In the analysis, the satin weave unit cell was identified and modeled discretely by 3-dimensional finite elements, considering the interlaced fiber tow architecture microscopically. At the unit cell boundary, the corresponding periodic boundary conditions were applied. The results were analyzed to investigate the effect of microstructural parameters and boundary conditions. The conductivities were also obtained by experiments and both results were compared.
