“…During a 900°C pyrolysis, short fiber reinforced CFRP compounds, based on high FMB, high tenacity fibers, and a phenolic precursor, shrink by approximately 1% in the in‐plane direction and about 5% in the transverse direction 8 . In comparison, a 2D‐laminate, also based on high FMB, HT fibers, and a highly aromatic precursor (XP‐60), shows no geometry change in length and width after pyrolysis, but contracts in the laminate thickness by approxinately 4.4%.…”

The demands in space technology originally played the decisive role in the development of carbon fiber reinforced ceramic matrix composites (CMC). Within the last few years, the properties and the manufacturing methods were consistently improved, so that now the industry in general can share in the profits of this new class of composite materials. The liquid silicon infiltration (LSI) process is regarded as one of the most promising processes for industrial products, especially if the aspect of cost is considered. An overview of the design, manufacture, properties, and applications of C/C‐SiC ceramics, produced with the LSI process, is given in this paper.

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.

“…For the SF‐1 material, cut C fibers with a constant length of 40 mm were mixed with a powdery phenolic precursor and filled in a press die, densified (pressure >5 MPa), and cured at a maximum temperature of 250°C. Through this process, a fiber volume content of 50% was reached in the CFRP preform 9 . Another low‐cost approach was pursued with the XNC‐1 material, where the process time for CFRP manufacturing and for the pyrolysis was reduced dramatically.…”

Novel C/C–SiC materials have been developed for their use as brake pads for high‐speed elevators. Under dynamic and stationary conditions, these materials exhibit high thermal shock resistance, high coefficients of friction, and extremely low wear rates. In addition, it has been found that the SiC content of the C/C–SiC materials on the friction surface heavily influences the frictional behavior. Low‐cost materials based on short fiber reinforcement and on drastically reduced process times showed their high potential for the manufacture of cost‐efficient brake pads.
