PBZ series fibre is known as ¡°21 century sper fibre¡±, due to it¡¯s high performance as like tenacity, specific modulus, heat resistance, antiflaming, soft and impact resistance, it becomes the strategic new material in defense, energy, traffic and transportation industries. Now it widely extended from aerospace aviation, defense military, impact resistance protection equipment industries into civil use(radiation resistance, high performance rope, sports), rail traffic, industrial use(high temperature resistance material, construction engineering reinforcing material,fibre optic communication cable reinforcing material) etc more than 20 industrial sectors.
