Alumina continuous fiber woven cloth

Alumina fiber woven fabrics are manufactured from high-strength continuous alumina fibers; their production requires no addition of other fibers or embedding of metal wires. This product can operate continuously at temperatures up to 1,400°C and exhibits excellent resistance to molten metal, making it suitable for applications such as insulation, shielding, sealing, and electrical insulation in high-temperature environments. The fabric structures include plain weave, twill, and satin weave. Among these, the M-99 unidirectional fabric is specifically designed for prepreg applications. It is characterized by the use of hot-melt yarns in the weft direction, allowing for easy removal upon heating. This product offers high precision, thermal stability, and exceptional performance in composite manufacturing.
