Solution details
Project introduction: Liquid crystal polyarylate fiber is a high-performance fiber with high strength and high modulus, high temperature resistance, chemical reagent resistance, radiation resistance, and excellent size stability. It has unique moisture and heat resistance, vibration attenuation performance and excellent wear resistance. This fiber is the only high-strength and high-modulus fiber prepared by melt polymerization and melt spinning methods. The production process is green and environmentally friendly. Donghua University has conducted systematic research on the synthesis, spinning and post-treatment of polyarylate since 2008, and successfully developed "flame-retardant high-strength liquid crystal polyarylate fiber."
Main features: The stratospheric airship skin material made of liquid crystal polyarylate fiber fabric not only has excellent mechanical properties, but also has stable size, effectively improving the floating height, continuous flight time, payload and service life of the stratospheric airship.
Application prospect: It can be used in aerospace, military, ocean development, electronics and electricity, communications, sports and leisure, etc.
