Kevlar yog ib lub npe ntawm cov hlab ntsha uas yog nkag tau rau lub lag luam los ntawm dupont hauv 1965. Kevlar ribbon yog ib qho khoom tshiab uas yog tsim los ntawm kev cov khoom muag kevlar. Nws muab siab rau lub zog thiab lub cev nyhav. Nws yog ib cov hlau hlau nyob hauv tib lub luj. Ob lub zog, 2.5 zaus lub zog ntawm e-qib iav fiber, thiab 10 zaug lub zog ntawm txhuas.
1. Muaj lub siab tawv thiab muaj zog
2. Tsawg elongation, high modulus, siab rhuav tshem lub zog
3. Kub kub, nplaim tsis kam, tsis muaj pob zeb, tsis muaj combustion, tsuas yog carbonization
4. Muaj tshuaj lom neeg muaj zog, muaj kev ruaj siab, thiab tsis kam mus ua ntsaum
5. Tsawg thermal expansion coefficient
6. Tsawg qee qhov nqhis
7. Hluav taws xob insulator
Kevlar webbing kuj muaj kev kub ua hauj lwm zoo heev, tsis yog tsuas siv tau rau tsis tu ncua hauv qhov kub kub ntawm tshem tawm 196 degrees mus rau ntxiv 204 degrees yam tsis muaj kev hloov lossis puas tsuaj; nws kuj muaj insolubilisation, hluav taws ua hauj lwm, tsuas yog carbonization yam ntxwv ntawm 427 degrees, txawm nyob rau hauv qhov tsawg kub ntawm rho 196 degrees, tsis ua brittleness thiab poob ntawm kev ua tau zoo, thiab muaj peev xwm tiv tau zoo kub kub ntawm ib lub sij hawm luv luv hu nrog ib tug kub ntawm mus txog 538 degrees.
Kevlar webbing yog dav siv nyob rau hauv cov tsheb thauj khoom siv, kev ruaj ntseg, cov khoom siv sab nraum zoov vim nws lub zog uas muaj zog thiab tsis ceev nrooj.
