“…The in-plane CTE of a single carbon fibre reinforced carbon composite prepared by CVI approach has not been reported in experimental studies. In Liao et al's work, the longitudinal CTE of a unidirectional C/C composite was measured in a temperature range of 25-1300°C [9]. They found that, the CTE of the carbon fibre tow was ranging between À0.4 Â 10 À6 /°C and 7 Â 10 À6 /°C and it reached to the peak value at about 1100°C (1373 K).…”

“…Luo measured the CTEs of C/C composites under the temperature ranging from 0 to 900°C [8]. Liao studied the CTEs of 2D and 3D C/C composites up-to 1300°C [9]; effects of density, porosity, preform architectures and heat treatment on the CTEs were investigated. Zhao et al [10] studied the effects of heat treatment, carbon fibre's orientations and graphitization degree on the CTEs of C/C materials.…”

“…Carbon fibre reinforced carbon (C/C) composites have unique properties like high melting point, high stiffness and toughness, better thermal shock properties, low coefficient of thermal expansion, etc., due to which C/C composites are used in aircraft brake applications, racing cars, and motorcycles [1][2][3][4][5]. C/C composites have high wear rate and poor oxidation resistance which limit its application [6,7].…”

Ceramic matrix composites made of carbon fibres and carbon matrix (C/C) are generally used for aircraft structures and brake discs due to their low density, and good thermal, mechanical, and tribological properties. Silicon carbide (SiC) can be introduced to the matrix to improve the performance of C/C composites, because it increases the hardness and thermal stability, and decreases the chemical reactivity, which leads to the improvement of tribological properties of C/C composites. Thus carbon-carbon silicon carbide (C/C-SiC) composites can be used at high temperature for the application of brake discs, friction clutches, etc. C/C-SiC composites are fabricated by three different methods: (i) chemical vapour infiltration (CVI), (ii) polymer infiltration and pyrolysis (PIP), and (iii) liquid silicon infiltration (LSI), among which LSI method is widely used for the fabrication of C/C-SiC composites due to higher mechanical and thermal properties.

“…Generally, the SiC or PyC with relatively low CTE was introduced into the composites as the bonding layer that connected the ceramics and the carbon fibers, in order to relieve the thermal mismatch of composites [10]. However, the SiC and PyC still possess the CTEs of 5.3 · 10 À6 [11] and 8.0 · 10 À6 /°C (Axis) [12], respectively, which were much higher than that of carbon fiber (À0.67 · 10 À6 /°C, Axis) [12]. Therefore, due to the differences in the CTEs of those materials, after processing and subsequent cooling of the composites from the high processing temperature to the ambient temperature, a residual thermal stress (RTS) develops in the composites [13].…”
