Ngo-2015, izinto ze-metal matrix composite foam zathuthukiswa ngokuhlanganyela ngabacwaningi abavela ku-DST kanye ne-New York University Institute of Technology.

Inokuminyana okungu-0.92 g/m3 kuphela futhi ingantanta emanzini. Ngokumangalisayo, le nto inamandla agculisayo ngenkathi ifinyelela isisindo esilula, futhi igobolondo layo elilodwa eliyindilinga lingakwazi ukumelana nokucindezela okungamaphawundi angu-25,000 iyintshi yesikwele ngayinye ngaphambi kokuphuka. Uma kuqhathaniswa ne-foam yensimbi yendabuko, inzuzo ye-foam eyinhlanganisela esekelwe ensimbi iwukuthi ukuminyana kungenziwa ngokwezifiso ngaphakathi kwebanga elithile, futhi usayizi nokuma kwezimbobo nakho kungalawulwa.

I-Metal Foam Porosity

I-Porosity ibhekisela esilinganisweni sevolumu yazo zonke izimbotshana emzimbeni onezimbotshana kuya kumthamo ophelele womzimba onezimbotshana, ukulinganisa okuvamile kwesikhala esingenalutho somzimba onezimbotshana. I-porosity yensimbi ye-foam ngokuvamile ifinyelela ngaphezu kwama-90%, futhi iyinsimbi enezimbotshana enamandla athile nokuqina. Lolu hlobo lwensimbi lune-porosity ephezulu, futhi ububanzi be-pore bungafinyelela ezingeni lemilimitha.

Ubuningi be-foam yensimbi benza izinto zensimbi ze-foam zibe nezicelo ezikhethekile. Isibonelo, Izinto zegwebu lensimbi ezisetshenziswa emkhakheni wokukhiqiza izimoto, zinganciphisa isisindo semoto, zithuthukise ukusebenza kahle kukaphethiloli, futhi zikhulise ukuvikeleka kwabagibeli uma kwenzeka kuba nengozi ngosizo lwekhono elihle lokumunca amandla.

Ekukhiqizeni kwangempela, kwatholakala ukuthi izingxenye eziningi zezimoto zingenziwa nge-aluminium enegwebu. Okufana nekhava engaphezulu, ikhava engezansi, izihlalo, obhampa, imishayo yobude bangaphambili nangemuva, njll. Isibonelo, iphaneli yophahla elenziwe ngesangweji legwebu le-aluminium elivela ku-Kaman Automobile Company yaseJalimane linokuqina cishe izikhathi ezingu-7 ngaphezu kwalokho kwezingxenye zensimbi, kodwa isisindo sawo singama-25% alula kunezingxenye zensimbi.

Inkomba: Umlando wokuthuthukiswa kwegwebu lensimbi

Ngo-1948, u-Sosnik uhlongoze ukulungiswa kwengxube ye-foam aluminium alloy ene-mercury vaporized, okwakuphawula okokuqala ukuthi abantu babe nomqondo we-foam yensimbi. Khonamanjalo, yaphula inkolelo-mlando yesikhathi eside yokuthi izinsimbi zinesakhiwo esiminyene kuphela.

Ngo-1951, u-Elliott wakhiqiza ngempumelelo i-aluminium enegwebu ngendlela yokuncibilika kwegwebu.

Ngo-1983, iphepha elanyatheliswa i-GJDVIES laphawula ukuqala okusemthethweni kocwaningo ngohlelo lwegwebu lensimbi, futhi ukucwaninga ngegwebu lensimbi kwaqala ngesikhathi esisebenzayo.

Ngo-1988, 《Porous Solids-structure & Properties》 eyanyatheliswa ngabakwa-LJ Gbson & MF Ashby kusewumsebenzi obalulekile emkhakheni wocwaningo lwezinto ezimbotshana.

Ngo-1991, i-Kyushu Industrial Research Institute yaseJapane ithuthukise inqubo yezimboni yokukhiqiza i-aluminium enegwebu.

Ngo-2000, u-Ashby nethimba lakhe bafingqa ngokuhlelekile indlela yokulungiselela, ukusebenza kanye nesiqondiso sokusetshenziswa kwegwebu lensimbi.

Kusukela ngo-2000, ubuchwepheshe bokulungiselela izinhlayiya ezinhle buye bavuthwa kancane kancane, futhi insimu yocwaningo ye-foam yensimbi nayo isiqalile ukukhula ngokushesha.
