The industry mainly uses Z953 aramid paper. Z953 aramid paper is a high-temperature rolled aramid honeycomb paper composed of pure aramid fibers, which is flame retardant, temperature resistant, low breathability, high mechanical strength, good stiffness, and good resin binding. Z953 honeycomb paper is used to prepare aramid honeycomb cores, which can be widely used in aircraft structures such as radomes, radomes, wall panels, hatches, and floors for military and civilian aircraft, as well as in spacecraft structures such as manned space stations and launch vehicle satellite fairings. It is an ideal structural material for aerospace and national defense industries.
