Investigating the Effect of Porosity on Thermal Characteristics of a 3D Orthogonal C-SiC Composite Using Finite Element Method

摘要

In this paper, finite element heat transfer analysis of a 3D orthogonal woven C-SiC composite is presented. Thermal transport properties of the composite are predicted in the three orthogonal directions. The effect of different manufacturing porosity types on thermal transport characteristics of the composite is also determined, which is achieved by using four unit cells constructed at different length scales. The predictive capability of the finite element models is benchmarked against the experimental results obtained from laser flash technique.
