Q: Why are carbon ceramic brake discs much more expensive than cast iron brake discs?
A: First, the raw material cost is high—carbon fiber and silicon carbide matrix materials are costly. Second, the production process is sophisticated, involving multiple steps such as preform weaving, chemical vapor infiltration (CVI), and high-temperature sintering, which results in a long production cycle. Third, the R&D investment is substantial, as it requires adaptation and testing for different vehicle models.
