Notes:
Three-dimensional finite element (FE) methods are used to predict the Young’s modulusof two types of 2D woven carbon/carbon composites. Tensile tests are performed to validate thepredictions. The results indicate that a novel image-based route in generating FE meshes gavestrong agreement with experimental data, while a comparative unit cell FE model of the structurewas found to be poorer. The differences between the image-based and unit cell methodologies werethe consideration of the finer architectures of the composites and their porosity. The image-basedapproach highlighted true porosity in the structure due to meshes forming directly from X-raytomographic data. However, the finer fibre architectures of the composites were compromisedbecause of limitations in the pixel resolutions employed during the initial scanning process. Incomparison, the unit cell models were based solely on idealisations of the composite microstructure,in which porosity was neglected
