Alumina Fiber Cloth

Alumina continuous fiber cloth is woven from continuous aluminum oxide fibres, with an Al₂O₃ content of 72% or more. It is a soft, high-quality, high-temperature resistant woven fabric with good chemical resistance, low shrinkage rate, low thermal conductivity, thermal shock resistance, low porosity, and unique electrical properties. It can be used for a long time in high temperature scenarios up to 1100 ℃ and above, and is widely used in market fields such as aerospace, automotive, electrical, composite materials, and high-temperature industry.
According to the different composition of raw materials, our alumina fibre cloth product models are divided into AF17, AF18, and AF19 series. The types of fabric organization are plain weave, twill weave, and five satin.
The mass production application of alumina continuous fibres is a significant advancement in refractory fibre technology. Due to its superior flexible processing characteristics, it can be carefully designed and woven into various soft fabrics such as fibre ropes, fibre belts, and fibre sleeves. It is an ideal choice for fire insulation, insulation sealing, and lightweight applications.

Product APPLICATION

Aerospace Field

Alumina continuous fiber can be used for hypersonic aircraft, antenna covers, and radar transmission covers. Using alumina continuous fiber as a new generation material with higher temperature requirements has become a trend. European and American countries have already applied this material to space shuttles, interstellar spacecraft, and weapon equipment, which can play a good role in temperature resistance and thermal insulation.

Industrial Refractory Material Field

Alumina short fibers can be used at temperatures ranging from 1200 ℃ to 1800 ℃. Their fiber products, such as fiber blankets, felts, paper, modules, and shaped parts, have low density and heat capacity, low thermal conductivity, and good thermal shock resistance. They can also be directly used as insulation filling materials for high-temperature kilns, such as furnace sidewalls, roofs, and doors, and as insulation seals for high-temperature components.
