Abstract

A ceramic matrix composite (CMC) plain weave composite material (DLR-XT) has been studied for its thermal transport behaviour. Three micro Unit Cell models have been developed for three different classes of manufacturing porosities, previously identified and quantified for the material, that take into account the thermal properties of the constituent materials. A finite element thermal analysis has been performed on each model to estimate the effect of each of the three types of porosity on thermal transport. The analyses have resulted in a cumulative set of spatial values of thermal conductivity, k, which can be used in a macro Unit Cell of DLR-XT composite material.
