Polyimide fiber

Fiber polyimide, nke a makwaara dị ka arylimide fiber, na-ezo aka na eriri molekụla nwere eriri arylimide.

The ike nke ether homopexed eriri bụ 4 ~ 5cN / dtex, na elongation bụ 5% ~ 7%, modulus bụ 10 ~ 12GPa, ike njigide ọnụego bụ 50% ~ 70% mgbe 100h na 300 ℃, na mmachi oxygen index bụ. 44, na nguzogide radieshon dị mma.Ketone copolymerization eriri nwere ihe dị ka akụkụ oghere oghere, ike 3.8cN/dtex, elongation 32%, modul 35cN/dtex, njupụta 1.41g/cm, shrinkage nke esi mmiri na 250 ℃ bụ ihe na-erughị 0.5% na 1%, n'otu n'otu.
