Yes, ceramic fiber products can be used in automobiles and aircraft. They are valued for their high-temperature resistance, thermal insulation, and lightweight properties. In automobiles, they are used in brake pads and exhaust systems due to their heat resistance. In aircraft, they are employed in heat shields, engine components, and insulation systems to withstand extreme temperatures and reduce weight, enhancing fuel efficiency and performance. Their use is particularly beneficial in high-performance and military vehicles where durability and heat management are critical.
