Abstract

In this paper, a study on the calculation, microstructure-sensitivity analysis and epistemic uncertainty quantification of the effective thermal conductivity and elasticity of Rayon FiberForm is presented. The 3D images of FiberForm were generated through X-ray Computed-Tomography (XRCT) technique. Based on the standard mechanics approach, the material properties of FiberForm were calculated by conducting numerical tests on the microstructures via finite element analysis. The microstructure sensitivity and convergence of calculated properties were systematically investigated. Additionally, the correlation between predicted properties and fiber volume fraction was examined. The ranges of calculated properties were also quantified based on the variation of fiber properties.
