Voxel Models as Input for Heat Transfer Simulations Based on X-ray Microtomography Images of Random Fiber Reinforced Composites

This paper proposes a method for the creation of a three-dimensional finite element model representing fiber reinforced insulation materials for the simulation software Siemens NX. VoxTex software, a tool for quantification of µCT images of fibrous materials, is used for the transformation of microtomography images of random fiber reinforced composites into finite element models. The paper describes the numerical tools used for the image quantification and the conversion and illustrates them on several thermal simulations of fiber reinforced insulation blankets filled with low thermal conductive fillers. The experimental measurements validate the prediction of the thermal conductivity.
