Chii chinonzi ballistic material? Inoshandiswa kupi?
Iyo yakajairika nhumbi dzokurwa nadzo dzinoshandisa mahwendefa eceramic semabaffles, asi ceramic inopwanya pane zvinokanganisa uye inorasikirwa nesimba rayo rekurwa kwakasimba. Zvidzitiro zvakawanda zvesimbi zvine dambudziko rimwe chete remabara anoputika pakubata. Zvimedu izvi zvinogona kukonzera kukuvara kune anopfeka nhumbi dzokurwa. Vapfeki vanoshandisa zvigamba zvezvombo zvechipiri kuzviso zvavo zvinogona kusagadzikana uye kuwedzera mutengo kumunhu, kambani, kana hurumende. Iko kuvandudzwa kwehuremu hwekurwisa matekinoroji senge ndege uye amphibious mota, pamwe nekudiwa kwekuwedzera mafambiro emauto epasi, ari kuda ballistic zvinhu zvinoramba zvichidzikisa huremu hwezvombo uku uchivandudza kuita kweballistic.
Ballistic nhovo inowanikwa mumhando dzakasiyana siyana uye mamakisi. Zvinhu izvi zvinoshandiswa kuchengetedza girazi, nhumbi dzokurwa dzemotokari, nhumbi dzokurwa nadzo dzemuviri uye nhoo. Laminated epurasitiki mapepa anopa huwandu hwakasiyana hwekudzivirira, kubva kune yakasimbiswa yakavharwa girazi kusvika kune tertiary ballistic zvinhu. Ballistic zvinhu zvinowanzo kuomarara, asi zvinogona zvakare kupfava. Inogona kuve yakaoma, senge Kevlar, UHMWPE, Lexan kana kabhoni fiber composites, kana nyore, senge.aluminium, simbi, titanium kana mamwe alloys.
Nekufambira mberi kwehunyanzvi, ballistic body armor yakachinja zvakanyanya. Musika wehembe dzemukati usingapindi bara uri kupupurira shanduko yakachengeteka uye yakareruka. Izvi zvakavhura nhandare nyowani yeComposite Metal Foam (CMF) tekinoroji, ichiibvisa kunze kwenzvimbo yekurapa maitiro kubva pamabhampa emotokari kusvika kumabvi ekutsiviwa.
Single kana composite foam masimbi ane basa reichi - aya mafuro ezvimiro muchimiro chesimbi isina simbi spheres, iyo yakamisikidzwa mumidziyo yeballistic sechinhu chepakati, asiwo seyepakati mune yakaoma maapplication senge simbi yezvombo, ceramics, uye fiberboard. Iyo furo haingomise kukwira kwemhepo yemabara nemabhomba, asi zvakare inoapwanya zvachose. Kunyange mabara anoboora zvombo, akagadzirirwa zvakananga kubvarura nhumbi dzokurwa nadzo, haagoni kupinda madziri.
Kune murwi, furo simbi mumidziyo yekudzivirira yemunhu inosanganisira:

• General Chinangwa Bulletproof Vests
• Active Flotation Bulletproof Vests
• Passive Floating Bulletproof Vests
• Tactical ballistic helmets
• Ballistic pfudzi uye mativi ekudzivirira zvombo seti
• Ne visor uye musana kudzivirira
• Ballistic nhovo

Kwezviridzwa zvinorema zvehondo pamwe negiya rekupona, furo simbi inoshandiswa kune akasiyana maapplication anosanganisira:

• Kugadzira zvombo zvakasanganiswa
• Kugadzira mabhesi emugodhi asingadziviriri emotokari
• Kugadzira mauto ekudonha mabhokisi

Chii chinonzi Foam Metal? Chii chinonzi Foam Metal uye ndezvipi zvinoshamisa zvimiro zvayo?
Foam metal isimbi ine porous metallic inoumba matatu-dimensional mesh chimiro mune esimbi matrix. Sezvo kune akawanda pores mukatifuro resimbi, saizi, nhamba, kufanana, kubatana uye kuvharwa kwema pores kunokanganisa maitiro ayo. Maparamita ane hukama zvakanyanya nemidziyo yefoam metals anosanganisira saizi yepore, yakazara porosity, inoshanda porosity, density uye chaiyo nzvimbo.
Foam simbi, serudzi rutsva rwezvinhu zvine zvese esimbi zvivakwa uye zvimwe zvakakosha zvemuviri zvimiro zvezvisiri-simbi zvinhu, iri kugamuchira zvakanyanya uye zvakanyanya kutariswa. Izvo zvakakosha zvefoam metal ndezvizvi:

• Ultra-mwenje zvinhu (75-95% yevhoriyamu ine nzvimbo isina chinhu)
• Yakanyanya porosity
• High compressive simba rakasanganiswa neakanaka simba rekutora zvivakwa
• Low thermal conductivity
• Simba repamusoro

Impact simba absorption musimboti wefoam metals
Pamusoro pekushandiswa kutengeserana kusefa, kuderedza ruzha, kuvharidzira uye zvinotakura zvinotakura,furo dzesimbivari mumiriri akasimba wekunyorera mucomposite armor system mumunda wekutora simba.
Semudziyo wekudzivirira weballistic, furo simbi chinhu chisina kuremerwa, chakasimba-chakasimba chine furo chakagadzirwa chichishandisa simbi isina mativi akaiswa mune yakasimba simbi matrix. Ichi chinyorwa chakaratidza yakanakisa mechaniki zvivakwa zvichienzaniswa nechero imwe simbi zvinhu. Aya emhando yepamusoro efoam metal anoteya simba nekukurumidza pakakwirira ballistic velocity maitiro kana ichienzaniswa nequasi-static loading.
Inowanikwa mune zvekutengesa magetsi anotora simba, ayo anowanzo kutora kinetic mechanical simba nekuritsikirira kana kuritsausa pakuremedza nguva dzose pamusoro pechinhambwe chakareba, anoshanda zvakada kufanana nezvitubu, asi anodzokera kumashure, achiaita midziyo yekuchengetedza simba kwete zvinotora simba.
Iyo porous dhizaini yemafuro esimbi inovapa yakasarudzika yekushushikana-strain curve; Kamwe kushushikana kwakaiswa kwakapfuura iyo extrusion plateau, furo rinotanga kudzvanya pane yakaringana kushushikana kunosvika 50-70% kushungurudza. Kuwedzerwa kwekunetsekana / strain curve kunotsanangura maitiro eiyo yakanakira simba rinotora.

Foam metal inoshanda sei pazvombo zvemuviri?
Foam simbi yakaratidza kuteya zvimedu zvebara uye kukudzivirira kubva kune chero kukuvara kwechipiri. Zvizhinji zvezvombo zvehondo zvehondo zvinoshandisa Kevlar-yakafanana seyekumashure, iyo inowanzo tariswa III-A uye inomisa kutenderera kwepfuti yega. Nhumbi dzakapfava dzinomisa mabara nekubvisa simba, uye sezvo mabara epfuti mazhinji asina kupinza semabara epfuti, unongoda kuadzikamisa kuti asapinde mukati meganda rako. Foam metal layer ndiyo inomwisa nhumbi dzokurwa nadzo dzemabara emagetsi epamusoro anoda kuti nhumbi dzokurwa dzimire. Iyo inowedzera chimiro chefuro resimbiinotamisa simba rekudhumhana zvakanyanya zvishoma zvakanyanya pane yakasimba zvikamu. Munzvimbo yekukanganisa, furo rinoenderana nyore nechinhu chinobata. Iyi purasitiki deformation munharaunda inotora simba remagetsi. Chero zvazvingava, shoma shoma yesimba rekudhumhana rinotorwa neiyo yakasimba. Vamwe vanhu vanosarudzawo kuwedzera chikamu chechitatu kuseri kwezvombo zvakapfava, zvinonzi trauma pad. Iri padhi rakagadzirwa nemateru asiri eNewtonian fluid uye padding. Zvinowedzera kudzikisira kukanganisa kwebullet kune anoripfeka.
