Mechanical properties of 3D KD-I SiCf/SiC composites with engineered fibre–matrix interfaces

Fabrication and properties of borazine derived boron nitride matrix wave-transparent composites reinforced by 2.5 dimensional fabric of Si–N–O fibers

“…In our previous work [18,19] The borazine infiltration and pyrolysis approach also possesses several advantages over conventional hot-pressing [20] and CVI [21] methods, such as easy processing, moderate fabrication temperature and high purity of BN matrix [22][23][24]. In the present investigation, to better evaluate the application potential of the Si-N-O f /BN composites, and then purified according to our previous work [25].…”

Temperature dependence of dielectric properties of SiCf/PyC/SiC composites

“…Based on Eqs. (8) and (9), the conductivity (T) of the PyC interphase in SiC f /PyC/SiC composite is inversely proportional to the temperature, which leads to the decrease of ε of the SiC f /PyC/SiC composite with increasing temperature. Fig.…”

“…One kind of them is the continuous silicon carbon (SiC) fiber-reinforced SiC matrix (SiC f /SiC) composite, which is a promising material for high-temperature structural applications, in part because of their superior properties, such as the high strength at elevated temperatures, the oxidation resistance, and the microstructural stability under neuron irradiation [1][2][3]. They are known to be a key material for components of aircraft engine hot-section components and fusion reactors [4][5][6][7][8]. Moreover, due to their excellent semi-conductivity and relatively stable dielectric characteristics at elevated temperature, they have also been showing many practical and potential applications in high temperature microwave absorption [9][10][11], for which the hightemperature complex permittivity is one of the most important parameters.…”

Mechanical and thermal properties of chemical vapor infiltration engineered 2D-woven and 3D-braided carbon silicate composites

“…Araki et al [13] examined the flexural properties of several high-density SiC f /SiC composites using Weibull distribution analysis. There have been a number of recent studies report continued developing of SiC f /SiC composites with 2D and 3D preforms [14][15][16]. We investigated 2D-woven and 3D-braided composites using CVI had improved properties for use in molten salt reactors.…”
