UHMWPE vs Aramid (Kevlar): Ballistic & Cost Comparison

Teb ceev: UHMWPE (ultra- siab-molecular- hnyav polyethylene) muab kev tiv thaiv sib npaug lossis zoo dua ntawm 30-50% qis dua aramid (Kevlar), thiab tiv taus dej, tshuaj, thiab UV - tab sis nws softens saum ~ 110-130 degree. Aramid tolerates kub thiab nplaim taws, thiab feem ntau pheej yig dua ib kilogram, tab sis absorbs ya raws thiab degrades nyob rau hauv UV. Rau feem ntau cov mos mos- armor panels, UHMWPE yeej ntawm kev tiv thaiv-rau- hnyav thiab tag nrho cov nqi; aramid yeej qhov twg tshav kub, nplaim taws, lossis stab kev ua tau zoo dominates.

Yog tias koj tsim cov khaub ncaws mos, kaus mom hlau, lossis stab- cov ntaub ntawv tiv thaiv, cov ntaub koj xaiv txiav txim siab tsis yog koj qhov kev xeem NIJ nkaus xwb, tab sis koj lub vaj huam sib luag hnyav, koj daim nqi ntawm cov ntaub ntawv, thiab thaum kawg seb koj qhov kev sib tw yog kev sib tw. UHMWPE thiab aramid (zoo tshaj plaws nyob rau hauv lub npe DuPont lub npe Kevlar®) yog ob qho tseem ceeb fibers nyob rau hauv mos ballistic tiv thaiv - thiab lawv coj txawv txawv nyob rau hauv tiag tiag armor pob.

Cov lus qhia no piv rau ob qho tib si fibers thoob plaws plaub qhov ntev uas ua rau muaj kev txiav txim siab yuav khoom: ballistic kev ua tau zoo, ib puag ncig zoo, tus nqi qauv, thiab daim ntawv thov haum. Nws yog sau rau lub cev armor manufacturers, armor - pab pawg neeg yuav khoom, thiab distributors nrhiav cov ntaub tiav - tsis yog rau kev kawm nyeem.

1. Yam Koj Yog Qhov Tiag Tiag

UHMWPE ntaub

UHMWPE yog polyethylene fiber ntau nrog cov hlua molecular ntev heev, muab lub zog siab tshaj plaws - rau - qhov hnyav piv ntawm cov khoom lag luam fiber ntau (txog ~ 15 × muaj zog dua hlau los ntawm qhov hnyav). Hauv qib ballistic nws yog siv ob hom:

UD (unidirectional) laminates - xoom- crimp fiber ntau txheej hauv 0℃/ 90℃orientation, laminated nrog nyias zaj duab xis. Fibers nyob ncaj ncaj, yog li lub zog kis mus rau sab nraud hla tag nrho daim ntawv es tsis txhob deforming lub crimp point.

Woven UHMWPE daim ntaub - hloov tau, drapeable ntaub rau nkhaus panels, stab pob, thiab hybrid tsim.

Aramid ntaub (Kevlar®, Twaron®, thiab generics)

Aramid yog ib qho muaj ntxhiab polyamide fiber ntau. Para-aramid (Kevlar, Twaron) muab lub zog tensile siab thiab kub tsis kam; meta-aramid (Nomex-type) yog siv los tiv thaiv nplaim taws. Hauv cov cuab yeej mos mos, woven para-aramid yog cov txheej txheem ib txwm muaj - xyoo caum ntawm cov ntaub ntawv, kev paub tob txog kev tsim khoom, thiab keeb kwm kev lees paub dav dav.

Ntawm Haining Yixin Cov Khoom Tshiab (SUN Composites), peb tsim ob lub fibers 'fab tsev neeg - UHMWPE ballistic fabrics, aramid fabrics, thiab carbon-aramid hybrids - ntawm peb tus kheej weaving thiab xov kab nyob rau hauv Zhejiang, Suav teb, uas yog precisely yog vim li cas peb yuav muab piv rau lawv ncaj ncees: peb muag ob qho tib si nyob rau hauv peb qhov profile, thiab peb cov lus pom zoo.

2. Kev sib piv ntawm Ballistic Performance

Cov lej txhais li cas hauv kev xyaum

Qhov hnyav. Rau kev hem phom phom txog NIJ IIIA (9 hli, .44 Magnum), UHMWPE UD vaj huam sib luag feem ntau ua tiav tib yam V50 thiab rov qab- lub ntsej muag deformation ntawm kwv yees li ob- thib peb ntawm thaj chaw ntom ntom ntawm lub vaj huam sib luag aramid. Rau cov neeg hnav lub tsho khuam, qhov sib txawv ntawd sib xyaw ua ke ntau dua 10- teev ua haujlwm - thiab rau tus neeg faib khoom, nws yog cov lus qhia tshwj xeeb ntawm cov ntaub ntawv.

Qhov chaw ntub dej. Aramid poob ballistic efficiency thaum ntub tshwj tsis yog kaw, thiab rov ntub / qhuav cycling accelerates fiber ntau degradation. UHMWPE yog polyethylene: nws tsis nqus dej kiag li, uas yog vim li cas nws thiaj li dominates marine, tropical, thiab humid- huab cua armor programs.

Kub. Qhov no yog aramid lub tsev turf. UHMWPE softens nyob ib ncig ntawm 110-130 degree, yog li aramid yog qhov kev xaiv raug rau cov neeg tua hluav taws- cov iav uas nyob ib sab, lub cav- cov ntaub thaiv npog, thiab txhua lub pob uas muaj cov cua sov ua kom muaj zog. UHMWPE lub melting point kuj tseem ceeb rau kev ntim khoom thaum lub thawv xa khoom mus rau cov huab cua kub - qhov tseeb tab sis muaj peev xwm tswj tau qhov kev nthuav dav.

Khawb thiab spike. Woven aramid's nruj crimp qauv resists txiav zoo dua UHMWPE UD, uas yog vim li cas muaj ntau stab -cov ntaub ntawv resistant (xws li, NIJ 0115.00- cov kev pab cuam style) tseem qhia aramid los yog aramid-nplua nuj hybrids.

Kuaj- hom ntawv ceeb toom: luam tawm V50 qhov tseem ceeb tsuas yog sib piv hauv cov khoom sib tw zoo tib yam - tib qhov projectile, rov qab av nplaum txias, thiab cov txheej suav. Thaum sib piv cov ntaub ntawv xa khoom, ib txwm nug: "V50 tawm tsam tus qauv twg, nyob rau hauv pes tsawg plies, ntawm qhov chaw ntom ntom?" A V50 tsis muaj pawg txhais yog tus lej lag luam, tsis yog engineering ib qho.

3. Tus nqi sib piv: Saib cov nqi ntawm qhov system, tsis yog nqi ib kilo

Qhov yuam kev ntau tshaj plaws uas peb pom yog muab piv cov khoom siv raw tus nqi ib kilogram thiab nres rau ntawd. Qhov sib piv kom raug yog tag nrho cov nqi ntawm ib lub vaj huam sib luag tiav, vim hais tias cov fibers qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm txhua qhov qis.

Peb txheej txheej nqi

Raw khoom nqi. Khoom muag para-aramid ntaub feem ntau pheej yig dua ib kilogram dua ballistic-qib UHMWPE UD laminate - feem ntau los ntawm lub ntsiab lus paj, nyob ntawm qib aramid thiab xaj ntim.

Areal density multiplier. Vim hais tias aramid yog ~ 48% denser thiab xav tau ntau plies rau kev tiv thaiv vaj huam sib luag, tib lub vaj huam sib luag tiav siv ntau dua kilograms ntawm aramid. Ib lub vaj huam sib luag uas xav tau, hais tias, 25 plies ntawm aramid yuav xav tau qhov sib npaug sib npaug hauv UHMWPE tsawg dua los ntawm qhov hnyav.

System- qib kev txuag. Cov vaj huam sib luag sib dua txhais tau tias tsawg dua thauj khoom hnyav rau ib chav tsev, ntim nyias nyias, thiab - rau cov tsheb lossis cov kev pabcuam hauv hiav txwv - cov roj ncaj qha lossis cov nyiaj them poob haujlwm. Rau cov khoom hnav, qhov hnyav yog qhov sib tw muag khoom uas txhawb nqa qhov kawg siab dua - tus nqi siv.

Tus nqi tsim nyog	UHMWPE	Aramid
Raw ntaub nqi (ib kg)	Siab dua	Feem ntau qis dua
Kg xav tau ib qhov sib npaug - tiv thaiv vaj huam sib luag	qis	Siab dua
Cov vaj huam sib luag tiav qhov ntom ntom	Lower (lub teeb)	Siab dua
Shipping hnyav rau ib chav tsev	qis	Siab dua
Humid / marine kev pab lub neej	Ntev (tsis muaj dej noo)	luv dua tshwj tsis yog kaw
Thaum tshav kub kub / nplaim taws pab ib puag ncig	Txwv (~ 110-130 degree)	Zoo heev

Cov tswv yim xaus: ntawm qhov sib npaug ntawm kev tiv thaiv, qhov ua tiav - vaj huam sib luag tus nqi sib txawv ntawm ob lub fibers feem ntau nyob deb me dua li ntawm -kilogram tus nqi sib txawv qhia - thiab hauv lub teeb yuag - qhov kev twv, UHMWPE nquag yeej ntawm tag nrho cov nqi. Aramid tseem yog qhov kev xaiv kev lag luam uas nws qhov hnyav raug nplua thiab nws cov thermal lossis stab zoo yuav tsum tau.

4. Yam Fiber rau yam khoom twg?

Koj cov khoom	Pom zoo lub hauv paus	Vim li cas
Concealable soft armor tsho khuam (NIJ IIIA)	UHMWPE UD	Lightest pob; noo- pov thawj rau hnav thiab tawm hws txhua hnub
Marine / tropical deployment armor	UHMWPE	Zero dej nqus; tsis ntub-kev ua haujlwm poob
Stab-cov tsho tiv thaiv / tiv thaiv- tom qab vaj huam sib luag	Woven aramid los yog hybrid	Crimp qauv resists txiav thiab spike
Hluav taws kub- kev pab cuam lossis siab - cov iav raug tshav kub	Aramid (para + meta)	Tsis muaj melting point; kev coj cwj pwm
Ballistic kaus mom hlau (composite)	UHMWPE UD los yog aramid, los ntawm qhov hnyav lub hom phiaj	UHMWPE rau qhov hnyav tsawg kawg nkaus; aramid rau cua sov- siv nyob ib sab
Tus nqi - tsav tsheb sib tw (qhov hnyav tsis tseem ceeb)	Aramid	Tus nqi qis raw khoom; mature supply chain
Cov kev pab cuam zoo tshaj plaws	UHMWPE los yog UHMWPE/aramid hybrid	Qhov hnyav spec yog qhov muag muag

Tsis txhob saib hybrid stacks

Ntau qhov zoo tshaj plaws - ua cov khoom siv armor tsis yog "los yog." Ib qho kev sib koom ua ke ua ke UHMWPE UD ballistic core nrog ib qho aramid lossis aramid- sib xyaw lub ntsej muag lossis nraub qaum rau stab thiab tshav kub. Hybrid designs cia koj coj UHMWPE qhov hnyav txuag qhov twg nws suav thiab aramid lub durability nyob qhov twg nws suav - thiab vim Yixin weaves UHMWPE, aramid, thiab carbon-aramid hybrid fabrics rau tib lub site, peb muaj peev xwm tsim thiab sim hybrid stacks raws li ib tug neeg muab khoom es tsis txhob yuam koj ob tug vendors.

5. Tsib Kev yuav yuam kev kom zam

Muab cov ntaub ntawv sib piv nrog cov ntawv xeem sib txawv. Ib txwm normalize V50 kev sib piv rau tib lub projectile, ply suav, thiab qhov ntom ntom.

Yuav ntawm tus nqi ib kilogram xwb. Hloov mus rau tus nqi ib lub vaj huam sib luag tiav ntawm kev tiv thaiv sib npaug - uas yog tus lej koj BOM xav tau tiag tiag.

Tsis quav ntsej qhov chaw pabcuam. Ib qho av noo- kev xa tawm huab cua tuaj yeem ntsiag to tshem tawm aramid tus nqi kom zoo dua los ntawm kev ua haujlwm luv luv.

Qhia txog UHMWPE rau cov khoom kub - pabcuam. Txhua lub pob uas muaj kev cuam tshuam ntev tshaj li ~ 110℃xav tau aramid lossis kev tiv thaiv vaj tse.

Txais batch tsis muaj traceability. Ballistic ntaub yog cov ntaub ntawv pov thawj, tsis yog khoom muag. Xav tau daim ntawv pov thawj ntawm kev tshuaj ntsuam thiab ntau traceability ntawm txhua qhov khoom xa tuaj.
