Feature ntawm Kevlar Fabrics

Feature ntawm Kevlar Fabrics

Kevlar fibers muaj cov khoom sib txawv ntawm lwm cov xov. Lub zog tensile thiab elastic modulus ntawm cov fiber ntau no ntau dua li yav dhau los cov organic fibers, thaum lub fiber ntau elongation qis dua. Cia peb saib cov khoom ntawm Kevlar.

Lub zog tensile zoo heev

Thaum cov ntaub yog rub, nws lub zog tensile yog qhov siab tshaj plaws uas nws tuaj yeem tiv taus ua ntej detaching. Lub zog tensile yog qhov ntsuas ntawm qhov hnyav npaum li cas ntawm cov ntaub tuaj yeem tuav ua ntej tawg. Nylon muaj lub zog tensile ntawm txog 75 MPa, thaum Kevlar muaj lub zog tensile txog li 3,620 MPa.

zoo dua kub tsis kam

Kevlar tsis poob lub zog thaum txias lossis kub. Kevlar yog qhov zoo tagnrho rau cov khaub ncaws uas tiv taus nplaim taws xws li hnab looj tes thiab npog. Cov iav tiv thaiv ua los ntawm Kevlar tuaj yeem tiv taus qhov kub txog li 800 degree F, ua rau nws zoo tagnrho rau cov chaw tsim khoom uas muaj cua sov.

yooj yooj yim

Kevlar fibers tso cai rau cov tuam txhab tsim cov khoom lag luam uas hloov pauv tsis tau muaj zog. Kevlar yog qhov zoo rau kev siv tsoos tsho vim tias nws tuaj yeem txiav thiab txiav kom haum. Cov neeg ua haujlwm hauv txhua qhov chaw ntawm lub neej tsis tas yuav txi qhov hloov pauv kom nyab xeeb thaum hnav Kevlar PPE. Kevlar yog qhov zoo rau kev ua hnab looj tes, tsho, thiab lwm yam.

Cov neeg ua haujlwm hauv txhua qhov chaw ntawm lub neej tsis tas yuav txi qhov hloov pauv kom nyab xeeb thaum hnav Kevlar PPE. Kevlar yog qhov zoo rau kev ua hnab looj tes, tsho, thiab lwm yam.

Qhov zoo ntawm Kevlar ntaub

Kevlar tsis yog tsuas yog lub teeb yuag thiab siab zog, tab sis kuj muaj ntau yam zoo. Nws muaj kev cuam tshuam thiab khawb resistant thiab ruaj khov heev ntawm qhov kub thiab txias. Kevlar feem ntau yog siv nrog lwm cov ntaub ntawv los ua cov ntaub ntawv zoo dua, xws li cov neeg tua hluav taws cov khaub ncaws uas tiv taus hluav taws.

Kevlar yog tshwj xeeb tshaj yog siv nyob rau hauv high-end taug kev khau looj plab hlaub vim hais tias nws yog ob qho tib si waterproof thiab breathable thaum tov nrog lwm yam fabrics raws li ib tug composite. Kevlar khaws nws qhov yooj yim thaum ua ke nrog roj hmab hauv cov ntaub ntawv sib xyaw. Cov khoom sib xyaw no yog siv los ua cov roj tso tsheb hlau luam ntawm Formula 1 cov tsheb sib tw.

Txawm tias muaj kev sib tsoo, lub tank roj yuav khaws cov roj av kom zoo. Txawm tias tom qab kev sib tsoo ntawm kev kub ceev, cov ntaub yuav tsis raug torn los ntawm lwm yam tsheb. Roj av tsis xau los yog khiav tawm, tiv thaiv hluav taws thiab tawg. Lub teeb hnyav roj tank pab txo qhov hnyav tag nrho ntawm lub tsheb, ua rau lub tsheb sib tw nrawm dua.
