Kwi-2015, izinto ze-metal matrix ezidibeneyo ze-foam zaphuhliswa ngokudibeneyo ngabaphandi abavela kwi-DST kunye ne-New York University Institute of Technology.

Inoxinano lwe-0.92 g/m3 kuphela kwaye inokudada emanzini. Okumangalisayo kukuba, esi sixhobo sinamandla awonelisayo ngelixa sifikelela kubunzima obulula, kwaye iqokobhe lalo elinye elingqukuva linokumelana noxinzelelo lweeponti ezingama-25,000 nge-intshi nganye yesikweri ngaphambi kokwaphuka. Xa kuthelekiswa ne-foam yensimbi yendabuko, inzuzo ye-foam ye-metal-based composite kukuba ukuxinana kunokwenziwa ngokwezifiso ngaphakathi koluhlu oluthile, kwaye ubungakanani kunye nokumila kwemingxuma nako kungalawulwa.

I-Metal Foam Porosity

I-Porosity ibhekisela kumlinganiselo womthamo wazo zonke iipores kumzimba oxubileyo ukuya kumthamo opheleleyo we-porous body, ngumlinganiselo oqhelekileyo wesithuba esingenanto somzimba we-porous. I-porosity yensimbi ye-foam ngokuqhelekileyo ifikelela ngaphezu kwe-90%, kwaye yintsimbi edibeneyo enamandla athile kunye nokuqina. Olu hlobo lwesinyithi lune-porosity ephezulu, kwaye i-pore diameter inokufikelela kwinqanaba le-millimeter.

Ubuninzi be-foam yensimbi yenza izixhobo ze-foam zetsimbi zibe nezicelo ezikhethekileyo. Ngokomzekelo, izixhobo zesinyithi ezisetyenziselwa ukuveliswa kweemoto, zinokunciphisa ubunzima bezithuthi, ziphucule ukusebenza kakuhle kwamafutha, kwaye zikhulise ukukhuselwa kwabakhweli kwimeko yengozi ngoncedo lokukwazi ukufunxa amandla.

Kwimveliso yokwenyani, kwafunyaniswa ukuba iindawo ezininzi zeauto zinokwenziwa ngealuminiyam enogwebu. Njengesigqubuthelo esingaphezulu, isigqubuthelo esisezantsi, izihlalo, i-bumpers, i-front and longitudinal beams yangasemva, njl. kodwa ubunzima bayo bumalunga ne-25% elula kunezixhobo zentsimbi.

Isalathiso: Imbali yophuhliso lwe-foam yensimbi

Ngomnyaka we-1948, uSosnik ucebise ukulungiswa kwe-alloy ye-aluminium ye-foam kunye ne-mercury ephuhliweyo, eyaphawula okokuqala ukuba abantu babenombono we-foam yensimbi. ngelo xesha, yaphula ithiyori yemveli yexesha elide yokuba iintsimbi zinesakhiwo esishinyeneyo kuphela.

Ngo-1951, u-Elliott wavelisa ngempumelelo i-aluminiyam enogwebu ngendlela yokunyibilika.

Kwi-1983, iphepha elipapashwe yi-GJDVIES liphawule ukuqala ngokusemthethweni kophando lwenkqubo ye-foam yensimbi, kwaye uphando kwi-foam yensimbi yaqala ngexesha elisebenzayo.

Ngo-1988, 《I-Porous Solids-structure & Properties》 eyapapashwa ngu-LJ Gbson & MF Ashby isengumsebenzi obalulekileyo kwinkalo yophando lwemathiriyeli enemingxuma.

Ngowe-1991, iKyushu Industrial Research Institute yaseJapan iye yaphuhlisa inkqubo yoshishino yokuvelisa i-aluminiyam enogwebu.

Kwi-2000, u-Ashby kunye neqela lakhe baqale bashwankathela ngokucwangcisekileyo indlela yokulungiselela, ukusebenza kunye nolwalathiso lwesicelo se-foam yensimbi.

Ukususela ngo-2000, iteknoloji yokulungiselela iincinci ezintle ziye zakhula ngokuthe ngcembe, kwaye intsimi yophando ye-foam yensimbi nayo iqalile ukukhula ngokukhawuleza.
