“…Carbon fiber reinforced silicon carbide (C/SiC) composites have made it into several high-temperature aerospace applications, like nozzle extensions, combustion chamber components and thermal protection panels for re-entry [1,2]. The Institute of Structures and Design of the German Aerospace Center (DLR) has been continuously working on advanced C/C-SiC composites for future thermal protection and space propulsion systems [3,4]. The damage behavior of these materials must be known to allow a proper design of structural components.…”

“…Carbon fiber rein-forced silicon carbide (C/SiC) composite materials are favorable for thermo structural components due to their excellent specific mechanical properties, high thermal conductivity and thermo shock resistance. They have been made into several high-temperature (>1300 °C) aerospace applications, such as hot turbine engine components, leading edge applications for hypersonic vehicles, and load-bearing TPS structures for re-entry [1][2][3][4][5]. One obvious characteristic of the ceramic matrix composites such as C/SiC ceramics, is their brittleness, leading to the structures having almost no energy absorbing capacity.…”

A catastrophic accident may be caused for nearby spacecraft due to the damage occurred in C/SiC thermal protection structure. Therefore, it is significant to analyze the damage feature of the ceramic composite structure. Acoustic emission (AE) is an effective non-destructive testing method which is widely used in aerospace industry. However, some key problems should be solved when the AE technology applied to the engineering field. In this paper some propagation characteristics of AE waves in C/SiC plate were investigated based on the finite element method. Firstly, two kinds of AE sources were established by combining plate wave theory and finite element method. Secondly, a novel simulation model was established which included the mechanical characters of C/SiC composite. Then to simulate the AE source, a stepped load and a dipole force is applied to generate the release of power loss. Additionally, the results of simulation are validated through the AE experiment with the analysis method of Choi-Williams transformation. Finally, the attenuation of AE signals propagation in C/SiC plate is discussed. The results of this research work demonstrated that the simulation method of AE waves in C/SiC structure proposed in this paper can be effectively used to study the wave propagation phenomenon

Three different multiscale models, based on the method of cells (generalized and high fidelity) micromechanics models were developed and used to predict the elastic properties of C/C-SiC composites. In particular, the following multiscale modeling strategies were employed: Concurrent multiscale modeling of all phases using the generalized method of cells, synergistic (two-way coupling in space) multiscale modeling with the generalized method of cells, and hierarchical (one-way coupling in space) multiscale modeling with the high fidelity generalized method of cells. The three models are validated against data from a hierarchical multiscale finite element model in the literature for a repeating unit cell of C/C-SiC. Furthermore, the multiscale models are used in conjunction with classical lamination theory to predict the stiffness of C/C-SiC plates manufactured via a wet filament winding and liquid silicon infiltration process recently developed by the German Aerospace Institute.
