Three-way catalyst liner: alumina short fiber is mainly used to make the sealing liner of the outer layer of the three-way catalyst, which plays a role in fixing, sealing, vibration reduction and sound insulation of the catalyst honeycomb carrier.

Thermal insulation material: Due to its excellent heat resistance and thermal insulation performance, alumina short fibre can be applied to many thermal insulation systems of automobiles, such as exhaust pipes, brake discs, etc., so that it has a more stable friction coefficient, good braking effect and longer service life.

New energy vehicle battery shell: the power battery shell made of alumina fibre resin matrix composite material has high specific strength and modulus, good shock absorption, impact resistance, low resonance, excellent fire resistance and thermal insulation, good corrosion resistance and chemical stability, which can effectively protect the internal battery structure, ensure the battery service life, and greatly reduce the security threat caused by battery combustion.
