Cov yam ntxwv ntawm aramid fiber

Cov yam ntxwv ntawm aramid fiber ntau:
Cov fiber ntau yuav tsis hlawv, haus luam yeeb lossis yaj thaum raug hluav taws kub thiab kub;
Aramid fiber ntau tsis muaj tshuaj lom thiab tsis tawg;
Nws thermal decomposition kub yog 430-450 degrees;
Lub zog ntawm aramid fiber pib txo qis thaum nws yog rhuab saum 150 degrees;
Kevlar tsuas yog muaj zog dua thaum khov, nws tuaj yeem tiv taus qhov kub thiab txias (txog -200 degrees);
Cov khoom no yog ib qho hluav taws xob insulator.
Tsis tas li ntawd, cov ntaub aramid yog mos, noo noo-wicking, thiab breathable, ua rau nws yooj yim heev rau siv. Kev lees paub, qhov no tsis siv rau cov khaub ncaws tsim los ua haujlwm hauv cov nplaim taws thiab cua sov. Rau ntxiv cov cua sov ua haujlwm, aramid yog coated nrog txhuas. Cov khoom siv ntawm cov fiber ntau no tiv thaiv cov hluav taws xob hluav taws xob muaj zog, tiv tauj nrog cov chaw kub txog li 500 degrees thiab kub hlau tawg.

Nws kuj tseem yuav tsum tau ntxiv tias cov khoom siv yog lub teeb - ib 'meter' ntawm ntaub hnyav 30-60 grams, uas tsis yog pheej yig, tab sis nws cov khoom tiv thaiv zoo heev ua pov thawj tus nqi. Cov ntaub ntawv tiv thaiv yog me ntsis kim dua ntxiv nrog aramid xov, uas ua rau lawv tiv taus tearing thiab puas. Cov ntaub ntawv no yog siv los tiv thaiv cov hnab looj tes rau kev ua haujlwm thiab cov khaub ncaws ua kis las, hnab looj tes thiab khau khiab khau khiab.

Tau kawg, aramid fiber kuj muaj qhov tsis muaj zog-tsis zoo compression kuj. Nws lub zog compressive yog kaum npaug nws lub zog tensile. Yog li, aramid fiber ntau tsis haum rau lub luag haujlwm ntawm cov khoom siv hauv tsev. Tab sis nws muaj kev ua haujlwm ntau hauv lwm qhov kev lag luam: lub cev armor, log tsheb qaum, panels thiab fenders rau fighter dav hlau, Formula 1 tsheb, roj tank rau nkoj thiab yachts. Cov choj raug tshem tawm ntawm cov hlua muaj zog thiab cov hlua khi ua los ntawm aramid thiab yuav tsis xeb. Hluav taws kub-resistant, ruaj tiv thaiv hluav taws thiab hnab looj tes yog tsim los ntawm nws. Qhov no tsis yog ib daim ntawv teev tag nrho.

daim ntawv thov
Aramid fibers yog siv nyob rau hauv cov kev lag luam uas puas ntsoog thiab thermal stability, tsis tshua muaj structural stiffness thiab siab tshaj plaws lightness raws li zoo raws li zoo heev lub zog ntawm tsawg yuag yog qhov tseem ceeb tshaj plaws. Yog li tsis muaj qhov xav tsis thoob tias cov khoom siv no yog siv los tsim cov khoom siv tiv thaiv tus kheej, tshwj xeeb tshaj yog cov tsho tiv thaiv phom, kaus mom hlau.
