Abstract

The determination and prediction of mechanical loading capacity is necessary for newly developed Ceramic Matrix Composites (CMC), which are getting used in aerospace technology and many other areas in recent years. In this work Inverse Laminate Theory (ILT) and failure criteria will be studied in order to predict elastic properties and failure of various winding angles under uniaxial loading. The main objective of this work was to compute an equivalent UD-layer with elastic parameters and to adapt the Tsai-Wu failure criterion from fibre reinforced polymer composites for the WHIPOX material (Wound HIghly Porous OXide ceramic matrix composite). Full coverage of the material properties in different fibre orientations (±3°/±87°, ±15°/±75°, ±30°/±60° and ±45°) is evaluated by in-plane tension, compression and Iosipescu-shear tests, which are also used to validate the laminate theory and the failure model. A modified Tsai-Wu criterion with consideration of different winding angles and the material stiffness matrix has been developed. A good correlation between experimental and analytically calculated strength data is shown in this paper.
