The paper presents enhanced studies of investigation and modeling of failure properties for wound ceramic matrix composites with varied fiber orientations under tensile loading. Based on mechanical tests and microstructure analysis, the characteristics of a virtual equivalent unidirectional layer (UD-layer) were examined and treated as input for modified Tsai-Wu failure criterion. In order to predict the mechanical properties with more accuracy, particular features of the investigated material have to be taken into consideration: definition of two material modeling groups based on the analysis of microstructure; interaction between failure strength and strain through inelastic deformation; inclusion of inhomogeneities created due to the manufacturing process in the analytical model. Based on the good correlation between the experiments and the modeling results, it can be shown that modeling approaches, considering the above mentioned particular material features, allow a very accurate prediction of the mechanical properties under in-plane tensile loading of CMC laminates.
