Aramid 1414 filament chinhu chakaumbwa chakagadzirwa uye chakagadzirwa neDuPont Company muna 1965. Inobatanidza unhu hwakanaka hwesimba guru uye uremu hureru.Pasi pehuremu hwakafanana, inosimba kashanu sewaya yesimbi, 2.5 nguva yakasimba seE-grade glass fiber uye ka10 yakasimba sealuminium.Inofungidzirwa sefiber yakasimba kwazvo munyika, uye inoshandiswa zvakanyanya mukurwisa moto, indasitiri yemauto, chengetedzo, kutaurirana, kusimbisa uye mamwe minda.Kubva ipapo, China, Japan neSouth Korea dzakatevedzana dzakagadzira uye dzakagadzira.Kunyange zvazvo mutengo wacho wakakwikwidzana zvikuru, hutano uye kushanda zviri kure kubva kune mumwe.Yakanakisa tembiricha kuramba, Kevlar ine yakanyanya kugadzikana mukuita tembiricha.Haikwanise kungoshandiswa nguva dzose mukupisa kwe -196 ℃ kusvika 204 ℃ pasina shanduko iri pachena kana kurasikirwa, asi zvakare ine insolubility uye haina combustion-inotsigira (moto kuramba).Inongotanga kuita carbonize pa427 ℃, uye kunyangwe pakudzika kwakadzika kwe -196 ℃, hapana embrittlement uye kurasikirwa kwekuita, uye inogona kutsungirira tembiricha yakakwira se.
