“…The friction coefficient curve under dry condition reveals a "pre-peak" at the initial stage of braking and a rapidly increasing "tail peak" stage at the end of braking. This "saddle-type" braking curve is consistent with that of previous C/C or C/C-SiC braking materials [11]. The friction coefficient curve under wet condition also shows a "pre-peak" at the initial stage of braking but no "tail peak" occurring at the end of braking.…”

Abstract:A novel braking material, C/C-ZrB 2 -ZrC-SiC carbon fibre-reinforced hybrid ceramic matrix composite, was prepared by chemical vapour infiltration and polymeric precursor infiltration and pyrolysis. Investigation of the microstructure of C/C-ZrB 2 -ZrC-SiC composite showed the homogenous dispersion of three-phase ceramic as the matrix. The frictional properties of the hybrid C/C-ZrB 2 -ZrC-SiC ceramic matrix composite were measured by a disk-on-disk type dynamometer under dry and wet conditions to simulate the normal landing state of aircraft brake disk friction pairs. C/C-ZrB 2 -ZrC-SiC ceramic matrix composite has a higher and more stable friction coefficient under wet condition than under dry condition, indicating that the composite has better performance compared with C/C or C/C-SiC braking materials.

“…[49,50] Additionally, silicon increases the wear rate and leads to the instability of friction behavior in the braking process. [51,52] The above two issues are supposed to be avoided by replacing residual silicon with high-toughness refractory phase. Nanolaminated Ti 3 SiC 2 is layered ternary carbide consisting of periodic planar stacking of edge-sharing Ti 6 C octahedral and close-packed silicon atoms along the c-axis, exhibiting elevated toughness and machinability.…”

“…[61] As a comparison, no self-lubricating oxide can be generated during braking for C/C-SiC, and the existence of silicon can increase the wear rate and lead to the instability of friction properties. [51,52] Therefore, the improvement of friction and wear properties can be attributed to the formation of selflubricating film-like debris, resulting from the replacement of residual silicon by Ti 3 SiC 2 .…”

Carbon fiber reinforced ceramic matrix composites (CFCCs) are promising materials for hightemperature applications. Due to the unique nanolaminated structure and special properties, the MAX phases are promising reinforcements for CFCCs. As one representative member of the MAX phases, Ti 3 SiC 2 has been in situ formed in C/C-SiC and C/SiC composites by a joint process of slurry infiltration and liquid silicon infiltration in recent years. The composites containing Ti 3 SiC 2 exhibited improved mechanical properties, tribological performance, and ablation behavior compared with those of unmodified composites. The introduction of MAX phases in CFCCs could extend their application fields effectively, and it is expected to bring more benefits to CFCCs by introducing the MAX phases in the future.

“…Chemical vapor deposition, chemical vapor reaction and liquid silicon penetration with silicon powders as raw materials have been applied as the preparation methods for siliconized graphite. However, with the presence of the residual free silicon in the matrix, the corrosion resistance and high temperature strength of composites were decreased, and the wear and instability of friction behaviors were increased [11][12][13][14] , in addition to the complex process and equipments.…”

SiC reinforced graphite composites were prepared via introducing carbide silicon into the natural graphite flakes (NGF) by hot-pressing process. Their physical and mechanical properties, including density, open porosity, flexural strength, and friction behavior were investigated. The addition of 30vol% SiC increased the bending strength of composites materials to 127 MPa, 2 times higher than 60 MPa of commercial pure graphite block. What was particularly interesting was that the as-obtained graphite composite with 30vol% SiC kept the same low friction coeffi cient of about 0.1 as pure graphite, and the wear resistance of composites increased.
