Fabrication and flexural properties of Tyranno-SA/SiC composites with carbon interlayer by CVI

In situ preparation of C–SiCxOy coatings with controllable composition on continuous oxygen-enriched SiC fibres

“…[4][5][6] In this case, bre layers are required to generate controllable weak bonding between the SiC bre and the ceramic matrix. 7,8 For the SiC-based bres, the most popular species of surface layers are known as pyrolytic carbon (PyC) and boron nitride (BN), [9][10][11] which are commonly prepared by a costly approach of chemical vapor inltration (CVI).

Effects of Pressure during Preform Densification on SiC/SiC Composites

“…The advantage of SiC/SiC composites comes from their low specific mass, superior thermomechanical properties and low activation [1][2][3]. As fabrication processes of SiC/SiC composites, there are three common processes, such as chemical vapor infiltration (CVI) [4], polymer infiltration and pyrolysis (PIP) [5] and reaction sintering/melting infiltration (RS/MI) processes [6]. However, total performances of these composites are still not satisfied for going of industrial stage.…”

Development of the tailored SiC/SiC composites by the combined fabrication process of ICVI and NITE methods

“…Several fabrication processes for SiC matrix densification, such as chemical vapor infiltration (CVI), polymer impregnation and pyrolysis (PIP), reaction sintering (RS) method, etc. have been under investigation for more than 10 years [4][5][6][7][8]. In the previous Japan-US collaborative JUPITER and JUPITER-II programs for nuclear fusion materials study, it was revealed that highly-crystallized SiC/SiC composites using advanced oxygen free, near-stoichiometric and crystallized SiC fiber had excellent resistance against neutron exposure [9,10].…”
