Single‐ and Multi‐Layered Interphases in SiC/SiC Composites Exposed to Severe Conditions: An Overview

The improvement in the mechanical and thermal properties of SiC/SiC composites by introducing CNTs into the PyC interface

“…These properties are highly dependant on their three constituents: the fibres, matrix and interface. In SiC/SiC composites, the interface plays a key role in their behaviour, such as preventing early failure of fibres, transferring load and heat between the fibres and matrix, and releasing part of the residual thermal stresses [6][7][8][9][10]. The most commonly used interfacial material in SiC/SiC composites for fusion/fission reactors is pyrocarbon (PyC) [11][12][13].…”

Synthesis of Pyrolytic Carbon Composites Using Ethanol As Precursor

“…Isothermal, isobaric chemical vapor infiltration was developed in the 1960s and represents the leading manufacturing process to densify fibrous preforms with a ceramic or carbon matrix to synthesize composites, in particular, carbon/carbon composites, which are used in the aeronautic, automotive, and fuel cell industry (brakes, pistons, and electrodes). − Due to the complexities of the pyrolysis of the precursor and the deposit formation, chemical vapor infiltration (CVI) from hydrocarbons into pyrolytic carbon (pyrocarbon) structures has also been of fundamental scientific interest. To reveal the essentials of CVI, most attention is paid to the impact of interactions among homogeneous gas-phase reactions, heterogeneous surface reactions, and transport phenomena on the microstructure and densification of pyrocarbon …”
