Yes, there are special requirements for using ceramic fibers in automotive manufacturing. These include high-temperature resistance, which is crucial for engine components; mechanical strength to withstand the stresses of automotive operations; chemical stability to prevent degradation from fuels and oils; and thermal insulation properties to manage heat effectively. Additionally, there are environmental and health considerations due to the potential release of fibers during manufacturing, which necessitates proper handling and safety measures. Compliance with industry standards and regulations for material safety and performance is also essential.
