Izinto ezintsha ezishisa izikhotha okwamanje -Metal Foam
I-Metal Foam inezinga elithile lamandla, i-ductility kanye ne-additivity, futhi ingasetshenziswa njengento engasindi yesakhiwo. Izinto sekuyisikhathi eside zisetshenziswa njengento eyinhloko yezingxenye zokubopha izindiza. Ezimbonini ze-aerospace kanye ne-missile, izinsimbi ze-foam zisetshenziswa njengezakhiwo ezisekelayo ezingasindi, ezidlulisa ukushisa. Ngenxa yokuthi ingahlanganiswa, ihlanganiswe noma ihlanganiswe nesakhiwo, ingenziwa ibe izingxenye ezithwala umthwalo we-sandwich. Njengegobolondo lensimbi ephiko lomzimba osekelayo, i-missile yekhala yegobolondo lokuwa kwe-anti-temperature yomzimba osekelayo (ngenxa ye-conductivity enhle yokushisa) kanye negiya lokuhlala le-spacecraft njalonjalo. Ekwakhiweni,igwebu lensimbiiyadingeka ukuze kwenziwe izinto ezilula, eziqinile, ezikwazi ukumelana nomlilo, izinsimbi noma indikimba yokusekela yalezi zinto. I-high-frequency, isivinini esiphezulu kanye nokwehla kwejubane kwamakheshi esimanje nakho kudinga izakhiwo ezingasindi ezinakho kokubili ukumunca amandla kanye nezakhiwo ezithwala umthwalo ukuze kuncishiswe ukusetshenziswa kwamandla. Amagobolondo angama-cylindrical asetshenziswa kakhulu ezakhiweni zobunjiniyela njengamafuselage endiza kanye namapulatifomu kawoyela asogwini. Amagobolondo angama-cylindrical anezindonga ezincane alimala kalula lapho engaphansi kwemithwalo, kodwa uma igobolondo lisekelwa igwebu eliqhubekayo: ikhoyili, isakhiwo sinamandla amakhulu kunegobolondo lesikhungo esingaqinisiwe sobubanzi nosayizi ofanayo. Igwebu le-Copper kulula ukukhiqiza futhi kulula ukuligoba, okwenza lifanelekele ukusetshenziswa njengesibopheli. Insimbi ye-Foam ingasetshenziswa futhi njengokuqinisaimpahlangezinto eziningi eziphilayo, ezingaphili nezensimbi. Okufana negwebu le-nickel eligcwaliswe ngokuqiniswa kwe-aluminium encibilikisiwe eyenziwe ngezinto zokwakha ze-nickel foam eziqinisiwe ze-aluminium alloy (NFRA).
Insimbi yegwebu ifaneleka kakhulu ukusetshenziswa njengamaphaneli okuthwala ahlukahlukene, amagobolondo namashubhu ekhoyili engasindi j, enziwe ngezinto ezihlukahlukene ezihlanganisiwe ezihlanganisiwe. Isibonelo esijwayelekile sokusetshenziswa kwezinto ezinama-porous zezingxenye zesakhiwo ukukhiqizwa kwamapaneli e-sandwich. Amasemishi panel asetshenziswa endizeni yesimanje asebenzisa ingilazi noma isikhumba se-carbon fiber composite. Izikhumba zihlukaniswa nge-aluminium yensimbi noma i-paper-resinizinto zekhekheba lezinyosi, noma ngamagwebu e-polymer aqinile, ukuze kunikezwe iphaneli yesemishi ukuqina okuphezulu okukhethekile okugoba namandla athile okugoba. Ubuchwepheshe obufanayo bunwetshiwe kwezinye izinhlelo zokusebenza lapho isisindo siyimethrikhi eyinhloko: izithutha zasemkhathini, ama-bobsled, izikebhe zomjaho, nezakhiwo ezinyakazayo, phakathi kokunye.

Ukuvikelwa kwe-Cushioning nakho kungenye yezindlela eziyinhloko zokusetshenziswa kwezinsimbi zegwebu, okumele zibe namandla okumunca amandla kuyilapho kugcinwa amandla amakhulu asebenza entweni evikelwe ngaphansi komkhawulo wokudala umonakalo. Izinto ze-foam ezinama-porous zingafaneleka kahle izicelo ezinjalo. Ngokulawula ukuminyana kwayo okuhlobene, amandla ensimbi ye-foam angalungiswa phezu kohlu olubanzi. Ngaphezu kwalokho, izinto ezibonakalayo zingakwazi ukumelana nezinkinga ezinkulu ezicindezelayo ngaphansi kwengcindezi ecishe ibe njalo, ukuze inani elikhulu lamandla lidonswe ngaphandle kokucindezeleka okukhulu. Ekulungiseni ithambo lokwenziwa, ngokwezidingo zobukhulu bembotshana obungu-150¨m ~ 250¨m kanye ne-porosity enkulu, izinto ezingaphili ngenxa yamandla alesi sikhathi azikwazi ukuhlangabezana nezidingo zokusetshenziswa, futhi kancane kancane zathuthukiswa zabaigwebu lensimbiithambo lokwenziwa. Lezi zinsimbi zegwebu zikhiqizwa ngezindlela ezijwayelekile ezifana ne-electroplating, futhi zingaphansi kwemithwalo ngesikhathi sokubunjwa nezinye izinqubo kanye nasemzimbeni womuntu. Kubaluleke kakhulu ezintweni eziningi zamathambo omuntu ezingenawo umphumela wokuzibuyisela ukuze kubonakale ukubola okukhulu okudingekayo emathanjeni omuntu kuyilapho kugcinwa izakhiwo eziphakeme zokumashini, okungukuthi, ukuhlangabezana ne-porosity enkulu edingekayo emathanjeni omuntu kuyilapho kugcinwa izakhiwo eziphezulu zemishini.
