“…Comparable material (CF 222) of Schunk Kohlenstofftechnik GmbH, Germany, has a specified interlaminar shear strength of 8 MPa, whereas high-quality C/SiC-material attains values of up to 48 MPa. 39,40 The low linear coefficient of thermal expansion (CTE) in the temperature range from 200-1200 • C of 0-2 × 10 −6 K −1 in the fibre direction is attributed to the fibre properties. The CTE of carbon fibres in this temperature range is quoted as −0.5-1 × 10 −6 K −1 in the axial direction.…”

“…39 The strength and fracture toughness are as expected significantly lower than that of high-quality, expensive C/SiC-materials with stiff matrices and fibre coatings for aerospace applications (bending strength up to 600 MPa, formal fracture toughness of more than 20 MPa × m 1/2 for bidirectional reinforced material). 40 All these related materials are reinforced with carbon fabrics, whereas the composite in this work is laminated. Nevertheless, as fibre type, matrix chemistry and/or porosity are similar, the comparison gives a reasonable impression of the competitive capability of the new material.…”

“…C/C-SiC composites have good resistance to oxidation and high static coefficient of friction, and the sensibility to environment is low. This makes C/C-SiC composites a potential material for aircraft braking system [11,25,28,66,67]. However, the density of C/C-SiC composites is higher than C/C composites which makes C/C-SiC composites heavier than C/C composites and limits their applications in some weight sensitive aircrafts.…”

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.

“…The C/SiC composites combined the advantages of PM and C/C brakes, and overcame most of the disadvantages of PM and C/C brakes, which exhibited a series of outstanding advantages such as low density, good high temperature resistance, high strength, excellent friction properties, low wear rate, and long life [1][2][3][4][5][6].…”

In this study, the short fiber C/SiC brake materials were prepared by a combined process of the fibers dipped with resin, chopping, warm pressing, pyrolyzing, and the liquid silicon infiltration process. The tribological properties of short fiber C/SiC brake materials and 30CrSiMoVA mate were investigated. The results indicated that the average friction coefficient decreased with the increase of braking speed (initial braking speed), and the friction coefficient tended to be constant when the braking speed was higher than 20 m/s. The braking was stable when the braking speed was 5 m/s, and the braking was unstable when the braking speed was higher than 10 m/s. The wear rate of the C/SiC increased with the increase of braking speed when the braking speed was less than 10 m/s, decreased with the increase of braking speed when the braking speed was less than 20 m/s, and then increased afterward with the increase of braking speed. When the braking speed was higher than 20 m/s, an oxidation-abrasion mechanism could occur. With braking speed increasing, the number of the ribbon debris increased, and the ribbon debris got long and thick, and the number of big granular debris increased.
