Ke hoʻopili ʻia i nā paia pale, aia ka Foam Aluminum ma ke ʻano o nā panela sandwich (FASP). Hoʻokō ʻia ka hoʻolālā panela sandwich maʻamau ma o kahi kaʻina hana composite, kahi i hoʻonohonoho ʻia ai ka pepa Foam Aluminum, e lawelawe ana ma ke ʻano he kumu,...

He mea metala ka metala huʻa me nā waiwai kū hoʻokahi, e hoʻohui ana i nā ʻano o nā metala a me ka huʻa, no laila kona inoa. No laila, he metala anei ka metala huʻa?

Ma ke kihi o ka ʻepekema mea holomua a me ka hana hou e waiho ana ʻo Copper Foam—he metala porous a maʻalahi hoʻi me kahi hoʻonohonoho kū hoʻokahi o nā waiwai e wehe ana i nā mea hou i nā ʻoihana like ʻole.

ʻO ka Aluminium Foam, kēia mea hoʻonaninani hou, e ʻālohilohi maoli ana e like me kahi momi nani i ka hoʻolālā hale hou. Hana ʻia ma ka hoʻohui ʻana i nā mea hoʻohua i loko o ka alumini maʻemaʻe a i ʻole nā ​​​​mea hoʻohui alumini, haʻaheo ia i nā waiwai māmā, ka ikaika kiʻekiʻe...

ʻO ka nickel foam, i ʻike ʻia hoʻi he metala huʻa, he mea pūnaewele porous ʻekolu-dimensional i haku ʻia me ka nickel metala. Hōʻike ʻia e ke alakaʻi uila kiʻekiʻe, nā waiwai māmā, ke ʻano like, kūpaʻa maikaʻi loa i ka corrosion...

He mea hana hou ka huʻa keleawe. Pehea e hana ʻia ai? ʻOiaʻiʻo, e like me ka hapa nui o nā huʻa metala, hoʻohana nui ka huʻa keleawe i ke keleawe ma ke ʻano he mea kumu. I ka wā o ka hana ʻana, he nui nā pores i hoʻopili ʻia a i ʻole i hoʻopili ʻole ʻia e hoʻokahi...

Ma ke ʻano he mea e pili ana i ke kaiapuni a māmā hoʻi, e ʻike ka huʻa alumini i nā manawa kūpono e hoʻonui ʻia i waena o nā koi e piʻi nei no ka mālama ʻana i ka ikehu a me ka palekana o ke kaiapuni ma nā ʻoihana like ʻole. Hoʻonui ka hana hou ʻenehana a me ka huahana...

Ma ke aupuni o nā mea holomua, he kakaikahi nā hana hou e hopu ana i ka noʻonoʻo e like me ka alumini huʻa. Kūʻē kēia mea kupaianaha i nā manaʻolana maʻamau o ka metala—he māmā, porous, a hiki ke lana ma luna o ka wa...

He mea hou ka huʻa alumini e hoʻololi nui nei i ka ʻenekinia kaʻa a me ka aerospace ma muli o kona hui pū ʻana o nā waiwai.

ʻO ka huʻa alumini kahi mea i hana ʻia ma ka hoʻohui ʻana i nā mea hoʻohui kikoʻī i ka alumini maʻemaʻe a i ʻole nā ​​​​mea hoʻohui alumini ma o ke kaʻina hana hua, e hoʻohui ana i nā waiwai o ka metala a me nā pehu. ʻO ke kaʻina hana e pili ana i ka hānai ʻana i ka alum i hoʻoheheʻe ʻia...

He kiʻekiʻe ke kūpaʻa o ka huʻa alumini i ka wela, a ʻaʻole ia e heheʻe ʻoiai ma kahi e heheʻe ai ka metala. ʻO ka pae mahana heheʻe no nā metala alumini maʻamau ma waena o 560 ~ 700 ℃, akā ʻaʻole e heheʻe ka huʻa alumini ʻoiai ke hoʻomehana ʻia a hiki i 1400 ℃. Fu...

ʻO ka huʻa alumini pani ʻia he ʻano mea hou me nā waiwai kino maikaʻi loa, hoʻohana nui ʻia i ka aerospace, ka hana kaʻa, ke kūkulu ʻana i ka insulation leo, a me ka hoʻoheheʻe wela o nā lako uila. Me ka hoʻolaha ʻana o ind...
