Alumina fiber needling blanket is made from alumina fiber prepared by sol-gel method through complicated needling process. Alumina fiber is composed of Al2O3 and SiO2, the internal structure of the fiber is dense, crystal type is stable, after acupuncture process, greatly improve the degree of interweaving between the fibers, has good delamination resistance, tensile strength and surface flatness, has better thermal insulation performance under high temperature conditions, can be used in more extreme environments for a long time.
