Cov yam ntxwv ntawm Aramid Fiber Composite Materials
Muaj zog tiv thaiv kev cuam tshuam thiab tawg
Aramid fibers muaj kev cuam tshuam zoo heev thiab yuav tsis tawg nyob rau hauv siab vim tias lawv tawv thiab tuaj yeem nqus tau ntau lub zog. Nws yog dav siv los ua cov tsho tiv thaiv mos txwv, cov tub rog marine, kayaks thiab cov khoom siv tub rog. Aramid fiber ntau muaj qhov cuam tshuam tsis zoo uas yog tsib npaug ntawm cov pa roj carbon fiber ntau (kuaj siv txoj kev poob qhov hnyav). Qhov kev cuam tshuam tshwj xeeb lossis cov mos txwv tiv thaiv no yog tshwm sim los ntawm cov saw ntev ntawm atoms uas ua rau cov qauv aramid.
Vim nws qhov kev cuam tshuam zoo heev, aramid fibers tau siv dav hauv kev siv tub rog los ua cov tsho tiv thaiv mos txwv thiab cov ntaub ntawv tank armor. Bulletproof vests feem ntau yog ua los ntawm cov ntaub ntawv uas muaj ntau ntau txheej ntawm aramid, xws li Kevlar, thiab muaj xws li ib tug ceramic phaj ntawm ob txheej. Cov ntaub thaiv npog siv nyob rau hauv qee lub tsheb armored (xws li US M1 tank) yog ua los ntawm steel-aramid-steel cov ntaub ntawv thiab tuaj yeem tiv thaiv cov cuaj luaj los tiv thaiv tank nrog txoj kab uas hla mus txog 700mm.

Tsis tas li ntawd, ntxiv rau kev tiv thaiv lub tank nws tus kheej, steel-kevlar-steel shield kuj tseem tuaj yeem tiv thaiv cov neeg coob los ntawm kev nqus cov kinetic zog tsim los ntawm kev nkag mus rau cov cuaj luaj. Lwm daim ntawv thov ntawm Kevlar yog nyob rau ntawm Boeing AH -64, ib tug workhorse attack helicopter ntawm US cov tub rog nruab nrog Kevlar rotors. Ntawm no, Kevlar muab kev tiv thaiv cov mos txwv mus txog 23mm inch.
