Kushandiswa kwemahwendefa eceramic kwakatanga muna 1918, mushure mekupera kweHondo Yenyika I, apo Colonel Newell Monroe Hopkins akawana kuti kuvhara nhumbi dzokurwa dzesimbi neceramic glaze kwaizowedzera kudzivirira kwayo.
Kunyange zvazvo zvinhu zveceramic zvinhu zvakawanikwa kare, hazvina kutora nguva refu zvisati zvashandiswa muhondo.
Nyika dzekutanga kushandisa zvakanyanya zvombo zveceramic yaive Yaimbova Soviet Union, uye mauto eUS akaishandisa zvakanyanya munguva yeHondo yeVietnam, asi zvombo zveceramic zvakangobuda semidziyo yekudzivirira mumakore achangopfuura nekuda kwemutengo wekutanga uye matambudziko ehunyanzvi.
Asi izvo, alumina ceramic yakashandiswa muzvombo zvemuviri muUK muna 1980, uye mauto eUS akagadzira yekutanga "plug-in board" SAPI muma1990s, yaive nhumbi yekudzivirira yekudzivirira panguva iyoyo.Yayo NIJIII yekudzivirira mwero waigona kubata mabara mazhinji anogona kutyisidzira vacheche, asi mauto eUS akange asati agutsikana neizvi.ESAPI yakazvarwa.
ESAPI
Panguva iyoyo, kudzivirira kweESAPI kwanga kusiri kwekubira, uye nhanho yekudzivirira yeNIJIV yakaita kuti ibude pachena uye kuponesa hupenyu hwemasoja asingaverengeki.Maitirwo azvinoita izvozvo pamwe hakusi kutariswa kwakawanda.
Kuti tinzwisise kuti ESAPI inoshanda sei, tinofanira kutanga tanzwisisa chimiro chayo.Yakawanda inoumbwa neceramic nhumbi dzokurwa nadzo chiumbwa checeramic chinangwa + simbi/isina-simbi kumashure chinangwa, uye mauto eUS ESAPI anoshandisawo chimiro ichi.
Panzvimbo pekushandisa silicon carbide ceramic inoshanda uye "ine hupfumi", Mauto eUS akashandisa inodhura boron carbide ceramic yeESAPI.Pandege yekumashure, mauto eUS akashandisa UHMW-PE, iyo yaidhura zvakanyanya panguva iyoyo.Mutengo wepakutanga UHMW-PE wakatopfuura iyo yeBORON carbide.
Ongorora: nekuda kweiyo batch yakasiyana uye maitiro, kevlar inogona zvakare kushandiswa sendiro yekutsigira neuto reUS.
Mhando dzebulletproof ceramics:
Bulletproof ceramics, inozivikanwawo semaumbirwo ekeramics, ine kuoma kwakanyanya, yakakwirira modulus hunhu, inowanzo shandiswa simbi abrasion, sekukuya mabhora eceramic, ceramic milling tool musoro.......Mune nhumbi dzokurwa dzakabatanidzwa, ceramics inowanzoita basa re "hondo yekuparadzwa".Kune akawanda marudzi eceramic muzvombo zvemuviri, anonyanya kushandiswa ndeye alumina ceramics (AI²O³), silicon carbide ceramics (SiC), boron carbide ceramics (B4C).
Maitiro avo akasiyana ndeaya:
Alumina ceramics ine yakanyanya density, asi kuoma kwacho kwakadzikira, chikumbaridzo chekugadzirisa chakaderera, mutengo wakachipa.Iyo indasitiri ine kuchena kwakasiyana yakakamurwa kuita -85/90/95/99 alumina ceramics, iyo label yakakwira kuchena, kuoma uye mutengo wakakwira
Silicon carbide density iri pakati nepakati, kuoma kwakafanana kuri pakati nepakati, ndekwechimiro chemakeramiki anodhura, saka mazhinji epamba anoisa nhumbi dzokurwa anoshandisa silicon carbide ceramics.
Boron carbide ceramics mumhando idzi dzeceramics mune yakaderera density, iyo yakanyanya simba, uye yayo yekugadzira tekinoroji zvakare yakakwira zvakanyanya zvinodiwa, tembiricha yepamusoro uye yakanyanya kudzvanywa sinter, saka mutengo wayo zvakare unodhura zvakanyanya makeramiki.
Kutora NIJ giredhi ⅲ ndiro semuenzaniso, kunyangwe huremu hwealumina ceramic yekuisa ndiro iri 200g ~ 300g kupfuura silicon carbide ceramic kuisa ndiro, uye 400g ~ 500g kupfuura boron carbide ceramic kuisa ndiro.Asi mutengo i1/2 yesilicon carbide ceramic insert plate uye 1/6 yeboron carbide ceramic insert plate, saka iyo alumina ceramic yekuisa ndiro ine mutengo wepamusoro uye ndeyemusika unotungamira zvigadzirwa.
Kuenzaniswa nesimbi bulletproof ndiro, composite/ceramic bulletproof plate ine mukana usingakundike!
Chekutanga, simbi yesimbi inorova homogeneous simbi nhumbi neprojekiti.Pedyo nemuganho wekupinda velocity, iyo yekutadza modhi yendiro inonangwa inonyanya kudzvanya craters uye shear slugs, uye kinetic simba rekushandisa rinonyanya kuenderana nebasa rekugera rinokonzerwa neplastic deformation uye slugs.
Kushanda kwesimba rekushandisa kweceramic composite armor zviri pachena kuti yakakwirira kupfuura yehomogeneous simbi simbi.
Kuita kwechinangwa checeramic kunokamurwa kuita mashanu maitiro
1: denga rebullet rakaputswa kuita zvidimbu zvidiki, uye kupwanya kwehondo kunowedzera nzvimbo inotangwa yekuita, kuitira kuparadzira mutoro paplate ye ceramic.
2: Kutsemuka kunoonekwa pamusoro pemakeramiki munzvimbo yekukanganisa, uye kutambanudza kunze kubva munzvimbo yekukanganisa.
3: Iyo nzvimbo yekumanikidza ine inokanganisa zone compression wave pamberi mukati meceramic, kuitira kuti ceramic yatyoka, hupfu hunogadzirwa kubva munzvimbo yekukanganisa yakatenderedza projectile ichibhururuka ichibuda.
4: kuputika kumusana kwekeramic, kuwedzera kune mamwe mazhenje emagetsi, kuputika kwakagoverwa mukoni, kukanganisa kuchaitika mukoni.
5: Ceramic iri mukoni yakaputswa kuita zvidimbu pasi pekunetsekana kwemamiriro ezvinhu, apo projectile inokanganisa ceramic pamusoro, mazhinji esimba rekinetic rinopedzwa mukuparadzwa kwenzvimbo yepasi yekoni, dhayamita rayo rinoenderana nemagetsi emagetsi uye zviyero zvejometri. ye projectile uye ceramic zvinhu.
Izvo zviri pamusoro zvinongori maitiro ekupindura eceramic armor pane yakaderera / yepakati kumhanya projectiles.Zvinoreva, maitiro ekupindura eprojekiti velocity ≤V50.Kana iyo projectile velocity yakakwira kupfuura V50, projectile neceramic zvinoparadzana, zvichigadzira mescall kupwanya zone uko zvese zvezvombo uye purojekiti muviri zvinoratidzika semvura.
Mhedzisiro inotambirwa neiyo backplane yakaoma kwazvo, uye maitiro acho ane mativi matatu-matatu muzvisikwa, nekudyidzana pakati pezvikamu zvimwechete uye nepakati peaya ari pedyo nefiber layer.
Mukutaura kwakapfava, kushushikana kwemafungu kubva pamucheka wave kuenda kune resin matrix uyezve kune yakatarisana layer, iyo strain wave reaction kune fiber intersection, zvichikonzera kupararira kwesimba rekuita, kupararira kwemafungu mune resin matrix, kupatsanurwa kweiyo. jira rejira uye kutama kwejira rejira rinowedzera kugona kweiyo composite kutora kinetic simba.Kutama kunokonzerwa nekufamba kwe crack uye kuparadzirwa uye kupatsanurwa kwemachira ega ega kunogona kutora huwandu hukuru hwesimba rekuita.
Kune yekupinda yekupikisisa simulation kuyedza kweakaumbwa eceramic nhumbi dzokurwa, kuyedza kwekuenzanisa kunowanzo gamuchirwa murabhoritari, kureva kuti, pfuti yegasi inoshandiswa kuita kuyedza kwekupinda.
Nei Linry Armor aine mukana wemutengo semugadziri wekuisa bulletproof mumakore achangopfuura?Pane zvinhu zviviri zvikuru:
(1) Nekuda kwezvido zveinjiniya, pane kudiwa kukuru kwezviumbwa zveceramics, saka mutengo wezvigadzirwa zveceramic wakaderera [mutengo wekugovana].
(2) Semugadziri wezvinhu zvakasvibirira uye zvigadzirwa zvakapedzwa zvinogadziriswa mumafekitari edu, kuitira kuti tigone kupa zvigadzirwa zvemhando yepamusoro uye mitengo inoshamwaridzana yezvitoro zvisingapindi bara uye vanhu.
