“…Advanced ceramic matrix composites (CMCs) based on a SiC matrix reinforced either with carbon fibres (Cf/SiC) or silicon carbide fibres (SiCf/SiC) are materials of great interest for aerospace [1,2,3] and nuclear applications [4,5,6] due to their superior mechanical properties, resistance against high temperatures and their light weight. CMCs typically consist of straight or woven ceramic fibres embedded in a ceramic matrix with a weak bond between them resulting in the improved fracture toughness of the materials [7]. They are being used as thermostructural materials in different fields, such as components of heat exchangers, gas turbines for power plants, heat shields for space vehicles (thermal protection system), inner wall of plasma chamber of nuclear fusion reactors, aircraft brakes, body flaps, leading edges, heat treatment furnaces, etc.…”

CVD-SiC coated and uncoated ceramic matrix composites were successfully joined to their counterparts with a pre-sintered Ti3SiC2 foil using Spark Plasma Sintering. For the first time pre-sintered Ti3SiC2 foil was used as a joining filler. The joining parameters were carefully selected to avoid the decomposition of Ti3SiC2 and the reaction between the joining filler and the CVD-SiC coating, which would have deteriorated the oxidation protective function of the coating.

The numerical prediction of composite material damages remains a strong tool that develops day by day. Several numerical models have been developed in the literature for simulating the progressive damage. In this paper the most used low velocity impacts numerical methods available in the literature are reviewed. First the various damage mechanisms of laminated composite materials are described. Then, different damages modelling are presented, from the onset to the final rupture. Finally, some results of the finite element model (FEM) are reported.

“…A thermodynamical formulation of the anisotropic damage model is discussed by Wulfinghoff et al by linking crack channels and pores with degradation in properties [13]. Models describing the damage of a homogenous CMC material at the macro-level have also been a topic of investigation for many researchers [14][15][16][17][18]. These models describe damage as the degradation of stiffness in principal material directions as the load increases.…”

This paper presents a damage-based failure criterion and its implementation in order to predict failure in ceramic matrix composites (CMC) manufactured via filament winding. The material behavior of CMCs is anisotropic and strongly depends on the angle between fiber orientation and loading direction. The inelastic behavior of laminates with different fiber orientations under tension and shear is modeled with the help of continuum damage mechanics. The parameters required for the damage model are obtained from a standard tensile and shear test. An isotropic damage law determines the evolution of damage in thermodynamic space and considers the interaction of damage parameters in different principal material directions. A quadratic damage-based failure criterion inspired by the Tsai-Wu failure criterion is proposed. Failure stress and strain can be predicted with higher accuracy compared to the Tsai-Wu failure criterion in stress- or strain-space. The use of the proposed damage limits allows designing a CMC component based on the microstructural phenomenon of stiffness loss. With the help of results obtained from modeling and experiments, fracture mechanics during the Iosipescu-shear test of CMCs and its capability to determine the shear strength of the material is discussed.
