I-foam ye-Copper yinto ene-porous eyenziwe kumxube we-metallic copper kunye ne-agent ye-foam engaphezulu, ebhaka kwaye yandiswe kumaqondo aphezulu. Kwisithando somlilo, i-foam yobhedu kulula ukuyikhupha emoyeni ngenxa yokuba iimolekyuli ze-oksijini zinokungena ngaphakathi kwi-foam ngokusebenzisa i-foam pores kwaye ziphendule ngobhedu ukuvelisa i-oxide yobhedu.

Isihluzi se-Ceramic foam sinokuthintela ngokufanelekileyo ukufakwa kwintsimbi engamanzi kwaye siphucule umgangatho wokujula kunye nesivuno, isihluzo se-ceramic foam sineendlela ezine eziphambili zokucoca ngokufanelekileyo isinyithi solwelo.

Ukwakhiwa kwezithintelo zesandi kumacala omabini ohola wendlela yindlela esebenzayo yokuthintela nokulawula ungcoliseko lwengxolo yendlela yendlela, izithintelo zesandi ezinobude obaneleyo, ubude, ngokubanzi, kunokunciphisa ingxolo ye-10-15dB. Ukuba ufuna ukuphucula inani lokunciphisa ingxolo, kufuneka ube kwisakhiwo kunye noyilo lwezithintelo zesandi, ukuphucula.

I-Silicon carbide ceramics yenza amaza kwintsimi yezinto eziphambili kunye nokusebenza kwazo okugqwesileyo kunye noluhlu olubanzi lwezicelo. Ukusuka kwiindawo ezinobushushu obuphezulu ukuya kwindawo eyonakalisayo neyonakalisayo, i-silicon carbide ceramics ibonakalise ukuba lukhetho oluguquguqukayo noluthembekileyo kumashishini ahlukeneyo.

Kwiindaba zamva nje, ilizwe lolwakhiwo lithe kratya ngokufunyanwa kwezinto ezikwazi ukumelana nomlilo – igwebu le-aluminiyam. Ezi zinto zintsha zinamandla okuguqula indlela esisondela ngayo ukhuseleko lomlilo kwizakhiwo, ukubonelela abaqulunqi kunye nabahlali ngamanqanaba amatsha okukhusela kunye noxolo lwengqondo.

I-foam yesilivere luhlobo olutsha lwezinto ezisebenzayo kunye ne-porosity ephezulu, indawo enkulu ekhethekileyo, kunye nokungena kakuhle, njl. ii-catalysts zesilivere ezikhoyo.

Ufakelo lwemathiriyeli ye-aluminiyam ye-foam ilula kwaye ilungile:
Kucetyiswa amanyathelo ofakelo eludongeni: ukuxhoma okomileyo → ikona engundoqo → i-vice keel → ipleyiti ejingayo okanye izikhonkwane ezizicofayo zidityaniswe nokuncamathelisa → iqhosha elingundoqo → i-vice keel → ukuncamathelisa (ngokwemozulu kunye noyilo loyilo lokuthintela umoya lokuxhoma okomileyo okanye ukuncamathelisa );
Ngenxa yokuba iphaneli ye-aluminiyam ye-foam ilula kakhulu, ukufakela isilingi kunokwenziwa ngokuthanda ukuncamathelisa, ukuxhoma kwe-I-beam, ukufunxa kazibuthe, kulula kakhulu.

I-nickel foam itsala ingqwalasela eyandayo kwintsimi ye-composites, ngokukodwa iimveliso eziveliswa yi-BEIHAI Composites. Esi sixhobo esiyingqayizivele sinoluhlu olubanzi lwezicelo kunye neenzuzo, okwenza kube yinto ebalulekileyo kumashishini ahlukeneyo.

Kwinkulungwane yama-21, ngezixhobo zomkhosi eziya zihambela phambili ngokwandayo, zombini ulwaphulo-mthetho kunye nokhuselo kufuneka luxhomekeke kwiinkqubo zenzululwazi, ezinamandla nezikhaphukhaphu zesikrweqe somzimba (izigcina-ntloko, iihempe zangaphantsi, amagxa, iimaski zobuso) ukuzinqanda ekubeni zijikwe zibe ngumxhesho wenkanunu.
Sesiphi isikrweqe somzimba esikhuselekileyo ngoku ekubeni iteknoloji yasemkhosini ihambele phambili? Impumelelo yamva nje ziihempe zangaphantsi ezingangenwa bullet ezenziwe ngogwebu lwentsimbi oludityanisiweyo olunokuqhawula imbumbulu ebhabhayo ngolonwabo.
Ayisiyo nayiphi na isinyithi, kodwa yenziwe ngokunyibilikisa i-aluminiyam malunga nebhola yentsimbi engenanto. I-foam yesinyithi edibeneyo ingaphezulu kwe-70% elula kunentsimbi yentsimbi eqhelekileyo - kwaye ifunxa amandla angama-80 ngaphezu kwentsimbi. Isikrweqe somzimba senziwe nge-foam yentsimbi edibeneyo kunye ne-boron carbide ceramic, ngelixa ipleyiti yangasemva yiKevlar.

I-Aluminiyam Foam Njengohlobo olutsha lwezinto zokuhombisa indawo ezifashiniweyo, i-Aluminiyam Foam ibonise umtsalane wayo okhethekileyo kunye namathemba osetyenziso olubanzi kwintsimi yokuhlobisa kwangaphakathi kwesakhiwo esikhulu.
