ʻO ka pahu metala, ma ke ʻano he ʻano mea hou, he ʻano ākea loa o nā noi. Ma muli o kāna mau hiʻohiʻona ponoʻī, ʻaʻole wale ka maikaʻi o ka hoʻopiʻi kūʻē ʻana, akā he maikaʻi loa ka plasticity a me ka additivity; i kēia manawa, hoʻohana nui ʻia ia i nā kahua aerospace a me nā pūʻali koa, a ma ke ʻano he ʻano mea hana māmā, hoʻohana nui ʻia i nā ʻano ʻoihana like ʻole.

ʻO ka pahu alumini kahi mea maikaʻi loa i loaʻa i ka manaʻo nui mai nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa. He mea porous māmā i haku ʻia me ka alumini paʻa me ka nui o nā pores pili. Hoʻohui kēia mea hou i ka ikaika, ka lōʻihi a me ka versatility, i mea kūpono no nā ʻano hana like ʻole.

I loko o ke ao o nā mea hoʻoheheʻe kani, ke hana nei ka pahu alumini i nā nalu ma ke ʻano he huahana kipi. Me kona mau waiwai kūikawā a me ka versatility, ke hoʻolalelale nei ka pahu alumini i ke ala no ka hoʻomohala ʻana i nā mea kani porous e hoʻololi hou ana i ka ʻoihana.

ʻO ka pau ʻana o nā wahie mōʻalihaku a me nā hopohopo e pili ana i ka ikehu a me nā pilikia kaiapuni i alakaʻi i nā hana noiʻi nui e hoʻomohala i nā kumu ikehu ʻē aʻe. Manaʻo ʻia ka electrolysis electrochemical o ka wai he hoʻolālā hoʻohiki no ka hana ʻana i ka wahie hydrogen.

I ka wā o ka ulu ʻana o nā kamaʻilio uea ʻole a me ka haumia electromagnetic, ʻoi aku ka nui o ka pono o ka hawewe electromagnetic maikaʻi ma mua o ka wā. ʻO ka pahu metala, ma ke ʻano he mea hou, hōʻike i ka mana nui i kēia kahua. Ua kālele ʻia ka noiʻi hou ʻana i ka ʻimi ʻana i ka ikaika o ka hawewe electromagnetic o nā ʻūhā metala, a he mea kupaianaha loa nā hopena.

I loko o ka nohona hou, mākou e kūkākūkā i ka leo keakea keia huahana ua oi aku, papa hana, halemai, kula, alanui hooponopono keʻena, a pela aku i ka pono no ka walaau ho'ēmi, i ke kaʻina hana o ke kuka ana, ka mea i ninau nui ia: pehea. hiki ke hoemi nui ia. I kēia manawa e hōʻike mākou iā ʻoe i ke kumu hoʻohaʻahaʻa leo o ka pale kani.

ʻO ka pahu alumini he mea māmā kiʻekiʻe, i hoʻohana nui ʻia i ka hana kaʻa, ka hoʻonani hale a me nā māla ʻē aʻe. No ka hanaʻana i ka pahu alumini, ponoʻoe e hoʻohana i keʻano o nā mea hana, e like me ka hanaʻana, ka hoʻouluʻana, ka maloʻo a me nā hana'ē aʻe. I ka hoʻohanaʻana i kēia mau mea hana, e hoʻolohe i ka palekana, hoʻololi a mālama i nā mea hana e like me nā kuhikuhi e hōʻoia i ka maikaʻi o ka hana a me ka hana pono o ka pahu alumini.

Ua like ke ano o ka pahu alumini me ka huahuakai a ua ike ia he metala honua, me ka haahaa haahaa a me ke kaumaha mama, i hoohana ia ma ke ano he papa pale no na kaa o ka lewa, ku e i ka compression a hiki ke ku i ka radiation-induced electrical impulses. He mea metala hou ia i hana ʻia me ka alumini alumini.

E like me ka hoʻohana nui ʻia ʻana o nā mea pale e hoʻohana i ka ikehu, ʻo ka hoʻohana ʻana i nā panela alumini foam sandwich (AFS) i hoʻopaʻa ʻia e nā waiwai mechanical haʻahaʻa o ke kumu pahu. ʻO ka hoʻohui ʻia ʻana o nā fibers carbon coppercoated (Cf) ua hōʻoia i ka maikaʻi i ka hoʻomaikaʻi ʻana i nā waiwai mechanical o ka pahu alumini.

Eia naʻe, ua kaupalena ʻia ka hoʻomaopopo ʻana i kāna kaʻina hana foaming a me ka microstructure. Ma kēia hana, ua hana ʻia ʻo AFS a me Cf/AFS e ka packing rolling powder metallurgy method. Ua ʻike ʻia ka ʻano huʻihuʻi o AFS a me Cf/AFS i nā mahana kiʻekiʻe me ka hoʻohana ʻana i ka synchrotron radiation X-ray imaging technology no ka noiʻi ʻana i ka hopena o Cf ma ka nucleation bubble, ka ulu ʻana, a me ka paʻa o ka huʻi. Eia kekahi, ua kālailai ʻia ka mahele nui o ka pore macroscopic, microstructure microscopic, a me nā waiwai mechanical compressive o AFS a me Cf/AFS. Ua hōʻike nā hopena i ka hoʻonui nui ʻana o ka Cf i ka nui o ka nucleation, hoʻomaikaʻi i ka paʻa ʻana o ka huʻa, a pale i ka hoʻokumu ʻia ʻana o nā ʻōpū nui maʻamau i ka wā o ka nucleation mua a me ke kaʻina ulu. I kēia manawa, hōʻike ʻo Cf/AFS i nā anawaena pore ʻoi aku ka liʻiliʻi ma mua o ka AFS. ʻO ka puʻunaue ʻana o Cf me ka pulu maikaʻi loa ma ka pā pore i pale aku i ka haki ʻana o ke kiʻiʻoniʻoni wai a hoʻemi i ka coalescence. Ua hōʻike ʻia ka hoʻokolohua hoʻopaʻa ʻana, i ka hoʻohālikelike ʻana me AFS, ua hoʻonui ʻia ka ikaika compressive a me ka hiki ke hoʻoemi ikehu o Cf/AFS ma kahi o 40.6% a me 84.8%, kēlā me kēia.

Ke ulu nui nei nā panela sandwich foam alumini i nā ʻoihana like ʻole ma muli o ko lākou mau waiwai kūikawā a me ka laulā o nā noi. Aia kēia mau paneli i kahi mea māmā māmā (e like me ka pahu alumini) i hoʻopaʻa ʻia ma waena o ʻelua mau ʻāpana alumini lahilahi. ʻO kēia hana hou e hana i ka mea ʻaʻole maʻalahi wale nō, akā ikaika nō hoʻi, kūpaʻa a me ka corrosion-resistant. Ma kēia moʻomanaʻo, e nānā pono mākou i nā hoʻohana a me nā pōmaikaʻi o nā panela sandwich foam aluminika, a me kā lākou hopena i nā ʻoihana like ʻole.
