Ceramic Fibre

Final Advanced Materials offers a full range of products in various forms of ceramic fibre: tapes, threads, sleeves, fabrics, etc.

What are Ceramic Fibres?

Final Advanced Materials can supply an innovative continuous polycrystalline ceramic fibre. The metallic oxides at the heart of its composition ensure that the processing of this fibre into ceramic textiles is particularly simple. It is mainly used in the aerospace, automotive, electrical and petrochemical industries.

This fibre also has a very low elongation and shrinkage rate thanks to its application temperature. As a result, manufacture is dimensionally stable. This continuous fibre demonstrates a mechanical and thermal performance that fibrous materials do not achieve, such as aramid, silica or glass fibres. In addition, this fibre has excellent chemical resistance, excellent dielectric strength, low thermal conductivity, good thermal shock resistance and low porosity.

General Characteristics of Ceramic Fibres

Physical and Mechanical Characteristics

Monofilament ceramic fibres are characterised by excellent dimensional stability thanks to their low shrinkage and elongation rate.

Moisture Uptake

Moisture absorption of monofilament ceramic fibres is extremely low. Thanks to their nonporous surface, the fibres are able to retain a maximum of 0.08 % of their weight in water.

Thermal Properties

Monofilament ceramic fibres have low conductivity and excellent resistance to high temperatures, making them an incomparable thermal insulator.

Benefits of Ceramic Fibres

Ceramic Fibres Products

Threads

Composed mainly of alumina (Al₂O₃) at different percentages, ceramic threads withstand operating temperatures up to 1,400 °C. They are primarily designed for thermal, electrical and mechanical applications subjected to extreme conditions, such as the manufacture of fire safety equipment and electrical or chemical insulators. Thanks to their great resistance to abrasion and mechanical stress, they are particularly suitable for sewing.

Sleeves

Ceramic sleeves can withstand operating temperatures up to 1,400 °C and peak temperatures up to 1,500 °C. They are particularly suitable for the insulation and the protection of cables, tubes, pipes and thermocouples. Final Advanced Materials proposes untreated ceramic fibre sleeves or with a heat cleaned finish. This treatment limits irritations during handling, the amount of smoke produced during exposure to high temperatures and airborne fibres.

Tapes

Ceramic tapes are resistant to applications involving operating temperatures up to 1,250 °C and peak temperatures up to 1,350 °C. They are particularly suitable for the thermal and electrical insulation as well as the protection of cables, tubes and pipes and the strenghtening packaged products. A heat treated or a heat cleaned finish is available: they can limit irritations for customised applications as well as flying fibres and the amount of smoke produced during exposure to high temperatures. They also prevent the physical degradation of the ceramic fibre.

Fabrics

Ceramic fabrics can withstand operating temperatures up to 1,400 °C and peak temperatures up to 2,000 °C. They are mainly used in the industry as heat shield and fire shield. The ceramic fabrics proposed by Final Advanced Materials are provided untreated. A version with a heat cleaned or heat treated finish is also possible. These treatments limit the irritations for customised application, the amount of smoke produced during exposure to high temperatures and minimise airborne fibres. They also prevent the physical degradation of the ceramic fibre when the products are subjected to hot and humid conditions for an extended period.
