Aramid fiber

A na-akpọ eriri Aramid polybenzoylenediamine, na carbon fiber, ultra-high molecular arọ polyethylene eriri na ụwa atọ isi elu-arụmọrụ eriri, dịtụ obere njupụta, elu ike, elu modulus, elu okpomọkụ na-eguzogide, corrosion eguzogide, mkpuchi, na-ọtụtụ-eji na agha, ikuku ikuku, ngwa eletrọnịkị, ụgbọ njem, ihe owuwu, ahụike na mpaghara ndị ọzọ. Aramid fiber bụ eriri polyamide synthetic aromatic, nke emere site na polymer linear sịntetik (opekata mpe 85% nke njikọ amide jikọtara ya na mgbanaka aromatic abụọ) nke mejupụtara amide bond interconnecting aromatic ring (Ar-CONH-Ar). Isi yinye bụ mgbanaka aromatic na njikọ amide, na usoro mgbanaka aromatic siri ike. A na-agbatị ụdọ polymer ka ọ bụrụ ihe owuwu dị ka mkpanaka.

N'otu oge ahụ, usoro ahịrị ahịrị nke yinye molekụla na-eme ka ọnụọgụ oghere nke aramid dị elu, yabụ olu otu ahụ nwere ike ịnabata polymer ọzọ, yabụ ike dị elu. Dị iche na ụdọ ụrọ molekụla polymer na-agbanwe agbanwe, usoro ihe eji arụ ọrụ nke eriri para-aramid bụ nke ihe mejupụtara mkpanaka yiri mkpanaka nke mgbanaka benzene mebere. N'ihi ọnụnọ nke nnukwu mgbanaka benzene conjugated, akụkụ ahụ yinye molekụla siri ike ịtụgharị n'ime, ya mere ọ na-enye usoro siri ike kwụ ọtọ.
