I-aluminiyam i-foam ifana ngokubunjwa kwesipontshi kwaye yaziwa ngokuba yintsimbi yendalo yonke, enoxinano oluphantsi kunye nobunzima obulula, esetyenziswa njengomaleko okhuselayo wezithuthi zasemkhathini, imelana noxinzelelo kwaye ikwazi ukumelana neempembelelo zombane ezibangelwa yimitha. Yimathiriyeli entsha yentsimbi eyenziwe ngengxubevange ye-aluminiyam enogwebu.

Njengezinto ezisetyenziswa ngokubanzi zokukhusela amandla, ukusetyenziswa kweepaneli ze-aluminium foam sandwich (AFS) zihlala zinyanzeliswa yimpahla ephantsi yomatshini we-foam core. Ukufakwa kwe-coppercoated carbon fibers (Cf) ibonakalise ukuba iyasebenza ekuphuculeni iimpawu zemishini ye-aluminium foam.

Nangona kunjalo, ukuqonda inkqubo yayo yogwebu kunye ne-microstructure kusenomda. Kulo msebenzi, i-AFS kunye ne-Cf/AFS zenziwe nge-packing rolling powder metallurgy method. Ukuziphatha okugwetyiweyo kwe-AFS kunye ne-Cf/AFS ngexesha lobushushu obunyusiweyo kwabonwa kusetyenziswa itekhnoloji ye-synchrotron yemitha ye-X-reyi yokujonga isiphumo se-Cf kwi-bubble nucleation, ukukhula, kunye nokuzinza kogwebu. Ngapha koko, i-macroscopic pore size distribution, microscopic microstructure, kunye necompressive mechanical properties ze-AFS kunye neCf/AFS zahlalutywa. Iziphumo zabonisa ukuba ubukho be-Cf bunyusa kakhulu izinga le-nucleation, kuphucula ukuzinza kogwebu, kwaye kuthintela ukubunjwa kwamaqamza amakhulu ngokungaqhelekanga ngexesha le-nucleation yokuqala kunye nenkqubo yokukhula. Ngeli xesha, i-Cf/AFS ibonise iidayimitha zepore ezintle kunye neziphene ezimbalwa kune-AFS. Ukusasazwa kwe-Cf kunye nokumanzi okugqwesileyo ecaleni kodonga lwepore kuthintele ukugqabhuka kwefilimu yolwelo kunye nokuncipha kokubambisana. Uvavanyo loxinzelelo lubonise ukuba, xa kuthelekiswa ne-AFS, amandla oxinzelelo kunye namandla okufunxa amandla e-Cf / AFS anyuke malunga ne-40.6% kunye ne-84.8%, ngokulandelanayo.

Iiphaneli ze-aluminium foam sandwich ziya zithandwa ngakumbi nangakumbi kumashishini ahlukeneyo ngenxa yeempawu zabo ezizodwa kunye noluhlu olubanzi lwezicelo. Ezi zixhobo zombane zibandakanya izinto ezingundoqo ezikhaphukhaphu (ezifana ne-aluminiyam yogwebu) ezifakwe phakathi kwamaphepha amabini abhityileyo e-aluminiyam. Olu lwakhiwo lutsha alunabunzima kuphela, kodwa lunamandla, luhlala luqinile kwaye lunokumelana nokugqwala. Kule bhlog, siza kujonga ngakumbi ukusetyenziswa kunye neenzuzo zeepaneli ze-aluminium foam sandwich, kunye nefuthe labo kumashishini ahlukeneyo.

Okwangoku, ininzi yoyilo oluchanekileyo kukunciphisa ubunzima bomzimba ngaphandle kokunciphisa ukusebenza komzimba, kwimeko enikeziweyo ukufumana indlela yokudlulisa engcono yomthwalo, ukwenzela ukuyila isakhiwo somzimba esingcono; Kwangaxeshanye, inani elikhulu lezinto ezintsha kunye nobuchwepheshe obutsha kunceda ukunciphisa ubunzima bomzimba, emva koko, oku kulandelayo kunye ukuqonda iingenelo kunye nokungalunganga kwezinto eziqhelekileyo ezilula!

I-Metal foam ifumana ingqwalasela kumashishini ahlukeneyo ngenxa yobunzima bayo kunye neempawu eziphezulu zamandla. I-China Beihai Composites Co., Ltd. yenye yabavelisi abahamba phambili be-foam yesinyithi kwaye inkampani iphambili ekuveliseni izinto ezintsha zokwenziwa kwezicelo.

I-Metal foam yimpahla yensimbi eneempawu ezikhethekileyo, ezinezinto zombini zetsimbi kunye ne-foam, ngoko ke igama lensimbi ye-foam. Ngoko, ngaba i-foam yensimbi yintsimbi?

I-Metal foam iya ithandwa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Enye yezinto eziphambili ze-foam yensimbi yi-porosity yayo, edlala indima ebalulekileyo ekunqumeni izinto eziphathekayo kunye nokufaneleka kokusetyenziswa okuhlukeneyo. Kule bhlog, siza kujonga ngakumbi ingqikelelo ye-porosity kumagwebu esinyithi kwaye sijonge ukuba ithetha ukuthini kwizicelo ezahlukeneyo.

I-foam yobhedu yenza amaza kubuchwephesha bebhetri ngenxa yeempawu zayo ezizodwa. Iyaziwa ngendawo yayo ephezulu kunye ne-thermal kunye ne-conductivity egqwesileyo yombane, eyenza ibe yinto efanelekileyo yokusetyenziswa kwebhetri. Nangona kunjalo, kusekho ukudideka malunga neempawu zayo zokuqhuba kunye nokuba yinto efanelekileyo yokusetyenziswa kwiibhetri. Kule bhlog, siza kuphonononga iipropathi ze-copper foam kunye nendima yayo enokubakho kwitekhnoloji yebhetri yexesha elizayo.

I-Aluminiyam i-foam yinto enomdla eya isanda kakhulu kwimizi-mveliso eyahlukeneyo ngenxa yeempawu zayo ezizodwa kunye noluhlu olubanzi lweenzuzo. Ukusuka ekubeni khaphukhaphu kwaye womelele ukuya kwiipropathi ezibalaseleyo zobushushu kunye ne-acoustic yokugquma, igwebu le-aluminium lingqineke liyinto exabisekileyo kwizicelo ezininzi. Kweli nqaku, siza kuphonononga izibonelelo ze-aluminiyam yogwebu kunye nendlela enokuguqula ngayo indlela esiyila ngayo kunye nokwenza iimveliso ezahlukeneyo.

Omnye wemiba ephambili ejikeleze i-foam yethusi yi-conductivity yayo, izinto eziguquguqukayo kunye neziguquguqukayo. Kule bhlog, siza kuphonononga iipropati ze-foam yethusi, iimpawu zayo zokuqhuba, kunye nezicelo zayo ezahlukeneyo.
