Enhancement of the Thermal Conductivity of Composites Reinforced with Anisotropic Short Fibers
SINOPSIS
Despite the importance of short-fiber composites in current engineering applications, few numerical studies have focused on their macroscopic heat conduction behavior. In this paper, we apply a finite-element-based methodology to calculate representative results for the effective thermal conductivities of composites reinforced with anisotropic short fibers. The investigated three-dimensional microstructures are ordered and consist of circular cylinders placed at the center of parallelepipedonal cells. The controlled parameters are fiber volume fraction, fiber and cell aspect ratios, and fiber thermal conductivity and degree of anisotropy. We identify the conditions under which the composite conduction capacity is significantly enhanced. Our numerical calculations are further contrasted to reported analytical and experimental results.
