The thermal conductive behaviors of 3D braided composites along in-plane and out-of-plane directions
were characterized and analyzed by multi-scale finite element analyses (FEA) and also validated by
experimental. Micro-scale representative volume element (RVE) was used to calculate the thermal conductivities
of braiding yarns, and the meso-scale RVE and full-scale braided model were developed to
research the thermal conductive behaviors of the whole braided composites. The differences of the
two models are also analyzed in this paper. Another attention of this paper was focused on revealing
the thermal conductive structural effects of braided composites.
