IFayibha yePolyimide

I-Polyimide fiber, eyaziwa ngokuba yi-arylimide fiber, ibhekisa kwikhonkco lemolekyuli equlethe ifayibha ye-arylimide.

Amandla e-ether homopexed fiber yi-4 ~ 5cN/dtex, i-elongation yi-5% ~ 7%, i-modulus yi-10 ~ 12GPa, izinga lokugcinwa kwamandla yi-50% ~ 70% emva kwe-100h kwi-300 ℃, i-oxygen indexing index 44, kunye nokumelana nemitha kulungile. Ifiber yeKetone copolymerization inecandelo elimalunga nomngxuma omile, amandla 3.8cN/dtex, elongation 32%, modulus 35cN/dtex, ingxinano 1.41g/cm, ukushwabana kwamanzi abilayo kunye ne-250℃ ngaphantsi kwe-0.5% kunye ne-1%, ngokulandelanayo.

Isetyenziselwa izinto zokucoca uthuli oluphezulu lobushushu, izinto zokugquma umbane, zonke iintlobo zobushushu obuphezulu kunye nempahla ekhusela ilangatye, iparashute, ubume be-honeycomb kunye nezinto zokutywina ubushushu, ukuqinisa izinto ezidibeneyo kunye nezinto ezichasene nemitha.
