Phakathi kwezixhobo ezahlukeneyo ezisetyenziswa kwintsimi yobunjineli, izinto zetsimbi ngokuthe ngcembe ziba yinto ebalulekileyo yolwakhiwo kunye nezixhobo ezisebenzayo ngenxa yeepropathi zazo ezigqwesileyo kwimiba emininzi enje ngoomatshini kunye neenkqubo. Kwiimathiriyeli eziqhelekileyo, imingxuma ngokuqhelekileyo ithathwa njengeziphene zesakhiwo, kwaye zihlala ziba yindawo yokwakheka kunye nokwandisa, ukuzisa imiphumo emibi okanye eyonakalisayo kwiipropati eziphathekayo. Nangona kunjalo, xa inani lemingxuma kwizinto eziphathekayo likhula kwiqondo elithile kwaye lihanjiswa rhoqo, ubukho bale mingxuma buya kwenza ukuba izinto eziphathekayo zibe neempawu ezikhethekileyo, ngaloo ndlela zenze iklasi entsha yezinto, ebizwa ngokuba yi-porous materials. Izinto zangoku ezenziweyo zibandakanya iiplastiki ezinamaqhekeza, iiseramikhi ezinobunwele, isinyithi esinemingxuma njalo njalo. Ngokuqhelekileyo kukholelwa ukuba xa i-porosity yezinto eziphathekayo ziyi-40% 98%, zinokubizwa ngokuba yizinto ze-foam. Isinyithi se-foam lisebe lezinto ze-foam, kwaye isakhiwo salo sinezi mpawu zilandelayo: ubukhulu bepore enkulu, i-porosity ephezulu, ubunzima obucacileyo obucacileyo, indawo enkulu yendawo ethile, kunye neyona nto iphambili ye-mesh skeleton yintsimbi.

I-Aluminiyam i-foam yintsimbi ye-foam esetyenziswa ngokubanzi, eyenziwe nge-aluminium skeleton kunye ne-pores, kwaye yinto entsha esebenzayo eyenziwa kumashumi eminyaka akutshanje. Njengesixhobo solwakhiwo, sineempawu zobunzima bokukhanya kunye namandla athile aphezulu: njengesixhobo esisebenzayo, sineempawu ezahlukeneyo zomzimba ezifana ne-porous, i-vibration damping, i-damping, i-sound absorption, ukutshatyalaliswa kobushushu, ukufunxa amandla kunye nokukhusela i-electromagnetic.
Nangona uluhlu lwesicelo sezinto ze-aluminium foam lubanzi, kodwa ngokukodwa lugxininise ekusebenziseni iimpawu zalo ezisebenzayo, kunye nokudlala iimpawu ezisebenzayo ze-aluminium foam zidla ngokuba yindleko yempahla yayo yomatshini. Indlela yokunika umdlalo kwiipropati ezisebenzayo ze-aluminium foam kwaye inokugcina isakhiwo sezinto ezintle zoomatshini iye yaba lukhokelo lophando oludumileyo, isisombululo esiqhelekileyo sangoku yi-aluminium foam - izinto zensimbi ezidibeneyo - ezifana ne "sandwich" i-aluminium foam, ingamandla. yentsimbi yomaleko womphezulu, i-aluminiyam igwebu kumqolo ongundoqo wesakhiwo sepaneli yesandwich. Eyona ndlela yokuvelisa i-aluminium foam sandwich panels, iipaneli ezidibeneyo ziquka ukudibanisa kunye ne-welding.
