Thermal Conductivity of Textile Composites with Arbitrary Preform Structures



In this paper, a model is constructed to predict the thermal conductivity of textile composite materials under steady state heat transfer conditions. First, the composite under consideration is geometrically characterized to identify relative volume fraction and spatial orientation of each yarn along its path. This is followed by applying finite element analysis (FEA) and virtual work to a “unit cell” of the textile composite. Hybrid hexahedra brick elements with fibers and matrix around each integration point are employed in the finite element formulation by means of micro-level homogenization. Thermal conductivity predictions using this approach are found to agree with experimental results for polymer and ceramic composites. The same approach can be used to solve other field problems including electrical conductivity, electrostatics, and moisture diffusion.
