“…Chemical vapor infiltration (CVI), liquid silicon infiltration (LSI) and precursor impregnation and pyrolysis (PIP) are most frequently used for the fabrication of CMC [2,3]. PIP has been intensively investigated during recent decades, because the products fabricated using this technique do not suffer from typical problems associated with LSI, such as residual Si and carbon fiber damage, or high costs associated with CVI [4].…”

In this article, the preparation, microstructure, and high-temperature stability of SiC-based ceramic fibers prepared from polycarbosilane of an organosilicon polymer are reviewed. The first fiber produced was an amorphous Si-C-O fiber, next was a low-oxygen content Si-C fiber, and finally, a nearly stoichiometric SiC fiber was developed. These fibers are continuous fine fibers that have high tensile strength with high heat resistance. The pyrolytic behavior and active-passive oxidation of these fibers at high temperatures are described here. The heat resistance of these fibers increases in the order of the Si-C-O fiber, the Si-C fiber, and the SiC fiber. The hightemperature properties are dependent on the atomic arrangement and the quantity of amorphous SiC x O y and glassy carbon in the fibers. Possible applications for these fibers are as refractory materials, and as reinforcement fibers for plastics, metals, and ceramics.

“…Nevertheless chemical curing could also be performed by exposing fibers to trichlorosilane what is often preferred for kinetic reasons. 159) Heat-treatment at 1500°C under nitrogen atmos- phere finally led to the obtaining of SiBN 3 C ceramic fibers. Diameter of the fibers ranged from 8 to 14¯m with tensile strength of 24 GPa and Young's modulus of 180350 GPa.…”

“…Ammonolysis (reaction with ammonia) led to unmeltable precursor while aminolysis (reaction with methylamine) yielded thermosetting oligomers which can then be polymerized in a controlled manner by varying temperature and reaction time. 158) Green fibers were subsequently produced by melt-spinning or dry-spinning. In this case curing was not a necessary step since extensive crosslinking of the polymer took place during the shaping.…”

High-temperature ceramic materials gain a continuous growing interest due to the various properties they can offer. Among all their specific features, their outstanding thermal and mechanical stability attract much attention to save energy. In the category of ceramics, silicon-based non-oxide compositions display a great potential for many applications involving high temperatures, high stresses or harsh environments. Since the major binary silicon carbide and silicon nitride, which are currently used as highperformance ceramics, were discovered, the role of chemistry in the design of materials has become major. Its potential lies in the exploitation of new chemical systems and the development of new preparative routes. As a consequence, new ceramic properties can be envisioned. The polymer derived ceramic (PDC) route is a "ceramic through chemistry" concept which allows synthesizing new materials in terms of compositions and shapes difficult to tailor using more conventional approaches. This review highlights the works made in the last decades concerning the preparation of PDC fibers with a particular focus on amorphous SiCN and SiBCN networks using melt-spinning and electrospinning processes of preceramic polymers. One main emphasis of this review is set on addressing the intimate relationship between molecular structure/architecture of preceramic polymers, their spinning/ curing/pyrolysis behavior and the properties of the final fibers.
