Alumina continuous fibre can be used for hypersonic aircraft, radomes and radar wave-transmitting hoods. It has become a trend to use alumina continuous fiber as a new generation of material with higher temperature requirements. European and American countries have applied this material to space shuttles, interstellar spacecraft and weapons equipment, which can play a good role in temperature resistance and heat insulation.

Alumina continuous fibre ceramic matrix composite has excellent high temperature strength, which can be used for rocket engine combustion chamber insulation layer, nozzle outlet cone and other related components, and is also an ideal material for thermal structure insulation connection between solid rocket engine nozzle and combustion chamber. In addition, it can also be used for hot end components of aviation turbojet engines.

Alumina continuous fibre reinforced metal matrix composites can be used for mechanical parts bearing high loads and high temperature and high speed rotating parts, such as the transmission of helicopters. It can also be used for solid rocket motor nozzle.

Alumina continuous fibre reinforced light alloy composite can be used in military industry, for example, reinforced aluminum matrix composite is an ideal material for armored vehicle and tank engine piston. The United States Army uses alumina continuous fiber reinforced composite material to manufacture tank track shoes, which reduces the weight from 544Kg of cast steel to 272-363Kg. It can also be made into solid motor shells for air-launched missiles. Its bursting pressure is the same as that of steel, and its mass is 11% lighter than that of aluminum alloy.
