Dhau li ntawm siab -kev ua tau zoo fibers, ceramics, hlau, thiab cov khoom ntse, carbon fiber, ultra-siab molecular hnyav polyethylene nonwoven npuag (UD npuag), thiab qee cov ntaub ntawv sib xyaw matrix kuj tau siv ntau hauv cov qauv tsho tiv thaiv. Lawv feem ntau ua haujlwm pab lossis txhawb cov txheej txheem, txhim kho kev tiv thaiv tag nrho thiab txo qhov hnyav.
1. Carbon Fiber – Ib qho siab -Lub zog, lub teeb yuag cushioning txheej khoom
Thaum cov pa roj carbon fiber nws tus kheej muaj peev xwm tiv thaiv ballistic, nws qhov siab modulus thiab qhov ntom ntom ua rau nws zoo tagnrho cov khoom siv rov qab los yog cushioning txheej.
Nws yog feem ntau siv rau hauv cov khoom sib xyaw ua ke, tso rau hauv qab cov khoom siv ceramic kom nqus cov khoom seem ntawm lub zog, tiv thaiv cov phaj rov qab tawg, thiab txo qhov kev pheej hmoo ntawm blunt quab yuam raug mob.
Nws kuj muaj kev siv dav hauv cov qauv ballistic ntawm qhov siab, tso tsheb hlau luam, thiab nkoj; Piv txwv li, aramid / carbon fiber hybrid composite daim hlau tuaj yeem txo qhov hnyav los ntawm ntau dua 30% piv rau cov ntawv hlau ib txwm muaj.
2. Unidirectional Fabric (UD Npuag) - Ib Daim Ntawv Qhia Txog Kev Ua Haujlwm Siab -Kev Ua Haujlwm Fibers
Qhov no tsis yog cov khoom siv tshiab, tab sis cov ntaub sib xyaw ua los ntawm unidirectionally npaj ultra- siab molecular hnyav polyethylene los yog aramid fibers thiab kho lawv nrog resin.
Piv nrog rau cov tsoos woven fabrics, UD ntaub nthuav tawm ntau yam fiber ntau kev nyuaj siab, siab zog hloov efficiency, thiab ho txhim kho tensile zog.
Nyob rau tib theem kev tiv thaiv, UD ntaub tuaj yeem txo qhov hnyav los ntawm 20% -30% piv rau cov tsoos aramid fabrics, ua rau nws yog ib qho ntawm cov khoom siv mos mos mos thiab muaj zog tshaj plaws tam sim no.
3. Resin thiab Polymer Matrix - Qhov tsis pom "Structural Glue"
Hauv UD npuag, cov khoom sib xyaw, thiab lwm cov qauv, cov khoom siv thermosetting resins (xws li epoxy resin) ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov fibers thiab hloov kev ntxhov siab.
Cov khoom ntawm cov resin ncaj qha cuam tshuam rau tag nrho cov rigidity thiab lub zog dissipation muaj peev xwm ntawm cov khoom. Thaum tsis ncaj qha muab kev tiv thaiv "bulletproof", nws yog ib qho tseem ceeb uas txiav txim siab qhov ua tau zoo ntawm cov mos txwv.
4. Ntuj Fibers (Cov ntaub ntawv keeb kwm) - Cov qauv thaum ntxov ntawm Bulletproof Vests
Nyob rau hauv lub xyoo pua puv 19, ntau- cov ntaub lo lo ntxhuav tau siv los ua cov tsho tiv thaiv cov mos txwv, muaj peev xwm tiv taus qis - cov phom phom nrawm, tab sis cov no tau kim thiab muaj kev tiv thaiv tsis muaj zog, thiab txij li ntawd tau raug txiav tawm.
Kev tshawb fawb niaj hnub no qee zaus tshawb txog kab laug sab cov ntaub ntawv sib xyaw. Piv txwv li, University of Trento nyob rau hauv ltalis infused graphene rau kab laug sab txhob lo lo ntxhuav, ua tiav lub zog 3.5 npaug ntawm cov kab laug sab kab laug sab, ua kom pom cov ntaub ntawv muaj peev xwm, tab sis kev tsim khoom loj tseem tsis tau pib.
5. Novel Composite Additives – Qhov tseem ceeb rau kev txhim kho ceramics
Thaum lub sij hawm sintering txheej txheem ntawm mos mos ceramics, multiphase additive hmoov (xws li Y₂O₃, AlN, thiab lwm yam) yog ntxiv rau optimize lub grain qauv, txhim kho ntom, thiab ua kom muaj kev cuam tshuam.
Txawm hais tias cov khoom siv ntxiv no tsis yog nws tus kheej tsim cov txheej txheem phom sij, lawv tseem ceeb heev rau kev txhim kho kev tiv thaiv kev ua haujlwm siab ntawm -kawg ceramics xws li silicon carbide thiab boron carbide.
