Product Introduction
Alumina continuous fibre is made of alumina and silica as the main component, and is prepared by sol - gel process. It can be used for high temperature above 1000℃ for a long time. It can be woven into soft fabric like fibre rope and fibre cloth. It can also be used for making many kinds of composite materials, and the form is convenient and flexible. It is an emerging high - tech industry and a variety of materials urgently needed in high - tech fields such as aviation, aerospace and new weapons for national defense.
