Izvo zvinopisa zvinhu zvitsva panguva ino -Metal Foam
Metal foam ine imwe dhigirii resimba, ductility uye kuwedzera, uye inogona kushandiswa seyakareruka zvimiro zvinhu. Izvo zvinhu zvagara zvichishandiswa sechinhu chakakosha chemidziyo yekumanikidza ndege. Mumaindasitiri emuchadenga neanopotsera, furo masimbi anoshandiswa seakareruka, kupisa-kutamisa zvivakwa zvekutsigira. Nekuti inogona kuve yakashongedzwa, yakanamirwa kana kuputirwa kune iyo chimiro, inogona kugadzirwa kuita sandwich inotakura zvinhu zvinotakura. Zvakadai seyebapiro resimbi ganda remuviri wekutsigira, iyo missile mhino yegomba re-anti-temperature kudonha kwemuviri wekutsigira (nekuda kweiyo yakanaka yekupisa conductivity) uye yekumhara giya respacecraft uye zvichingodaro. Mukuvaka,furo resimbiinodiwa kugadzira chiedza, chakaoma, chinodzivirira moto, simbi kana mutumbi wekutsigira wezvinhu izvi. Iyo yakakwirira-frequency, kukurumidza-kumhanya uye kuderera kwezvikwiriso zvemazuva ano zvinodawo zvimiro zvakareruka zvine zvese zvinotora simba uye zvinotakura zvinhu kuti zvideredze simba rekushandisa. Cylindrical shells anoshandiswa zvakanyanya muinjiniya zvimiro senge ndege fuselages uye off-mahombekombe oiri mapuratifomu. Matete-walled cylindrical shells anokuvadzwa nyore nyore kana akaiswa pasi pemitoro, asi kana goko racho richitsigirwa nefuro rinoramba riripo: coil, chimiro chine simba rakakura kupfuura isina kusimbiswa yepakati goko redhayamita imwechete uye saizi. Foam yemhangura iri nyore kugadzira uye iri nyore kutsvedza, ichiita kuti ive yakakodzera kushandiswa sefastener. Foam simbi inogonawo kushandiswa sekusimbisazvinhukune akawanda organic, inorganic uye metallic zvinhu. Senge nickel furo rakazadzwa neyakanyungudutswa aruminiyamu solidification yakagadzirwa nickel furo reinforced aluminum alloy (NFRA) zvinhu.
Foam simbi yakanyatsokodzera kushandiswa seakasiyana-siyana anotakura mapaneru, mateko uye machubhu e-lightweight j coil, akagadzirwa nemhando dzakasiyana-siyana dzakagadzirwa nelaminate composite. Muenzaniso wakajairika wekushandiswa kwemidziyo yeporous yezvikamu zvekuumbwa ndeyekugadzirwa kwemasangweji mapaneru. Sangweji mapaneru anoshandiswa mundege yemazuva ano anoshandisa girazi kana kabhoni fiber composite ganda. Matehwe anoparadzaniswa nesimbi aluminium kana bepa-resinzvinhu zvemuzinga, kana nemafuro akaomarara epolymer, kuitira kuti ipe sandwich panel kuomarara kwakakomba uye kubhenda kwakasimba. Iyo tekinoroji imwechete yakawedzerwa kune akati wandei mamwe maapplication uko huremu iri kiyi metric: space shuttles, bobsleds, mabhoti emujaho, uye zvivakwa zvinofamba, pakati pezvimwe.

Cushioning dziviriro zvakare imwe yeakanyanya kushandiswa kwefuro simbi, iyo inofanirwa kuve nekugona kutora simba uchichengeta iyo yakanyanya simba ichiita pane chinhu chakadzivirirwa pazasi pemuganho wekukonzera kukuvara. Porous foam zvinhu zvinogona kunyatsokodzera maapplication akadaro. Nekudzora huwandu hwayo hwehukama, kusimba kwesimbi yefoam inogona kugadziriswa pamusoro pehupamhi. Uye zvakare, iyo nyaya inogona kumirisana nehombe yekumanikidza pasi pekungogara kushushikana, zvekuti huwandu hukuru hwesimba hunobatwa pasina kushushikana kwakanyanya. Mukugadzirira pfupa rekugadzira, maererano nezvinodiwa zvepore size ye150¨m ~ 250¨m uye yakakura porosity, inorganic zvinhu nekuda kwesimba renguva ino hazvigone kusangana nezvinodiwa zvekushandisa, uye zvishoma nezvishoma zvakagadziridzwa kuitafuro resimbipfupa rekugadzira. Aya masimbi efuro anogadzirwa nenzira dzakajairwa senge electroplating, uye anoiswa pasi pemitoro panguva yekuumbwa uye mamwe maitiro pamwe nemuviri wemunhu. Izvo zvakakosha zvakanyanya kune mazhinji emunhu bhonzo zvinhu izvo zvisina yekuzvidzoreredza maitiro kuti aone hombe porosity inodiwa pabhonzo remunhu uchichengetedza yakakwirira michina zvinhu, kureva, kusangana nehombe porosity inodiwa pabhonzo remunhu uchichengetedza yakakwirira mechanical properties.
