ʻO ka pahu alumini mea hou he ʻano hou o ka māmā hana-hana i hoʻohui ʻia i nā mea i hana ʻia me ka alumini a i ʻole ka alumini alloy matrix a me ka pore composite, ʻo kēia ʻano kūikawā o ka pahu alumini mea hou e hoʻoholo ai i kona kaumaha māmā, porosity kiʻekiʻe, kiʻekiʻe kikoʻī kikoʻī a me nā ʻano ʻē aʻe, no ka loaʻa ʻana o nā metala paʻa he nui ʻaʻole i loaʻa nā hiʻohiʻona maikaʻi loa, e like me ka hoʻoulu ʻana o ka ikehu ikaika, ka hopena o ka hopena, ka ikaika kikoʻī kiʻekiʻe, ka pale electromagnetic, nā waiwai absorption leo, ka damping kiʻekiʻe Nā waiwai o ka alumini hou. Hoʻokumu nui ʻia nā mea puaa ma nā waiwai o ka pahu alumini. ʻO ka hana ʻana o ka alumini foam mea hou e hilinaʻi nui ʻia i ka porosity, ka nui o ka pore, ka ratio o loko o ka puka, ke ʻano o ka pore structure, kahi kikoʻī kikoʻī a me nā ʻāpana hana pore a me ka matrix metala.

ʻO ka hoʻohana ʻana i ka pahu alumini ma ke ʻano he mea hana, ma muli o ke ʻano o ka nui o nā pores i loko o ka pahu alumini, i loaʻa iā ia kahi paona māmā a me nā ʻano ikaika kikoʻī kiʻekiʻe a lilo i mea ʻoi aku ka maikaʻi o ka māmā composite sandwich panel a i ʻole ka hoʻopiha ʻana i ka wai. mea waiwai. Hiki ke hoʻomaikaʻi maikaʻi ka hoʻopihapiha hoʻopihapiha alumini i ke ʻano deformation o nā panela composite ma lalo o nā haʻahaʻa static a me ka ikaika, i hoʻomaikaʻi nui ʻia kona ikaika kulou, ikaika compressive, stiffness a me nā waiwai absorption ikehu. Ke hoʻohālikelike ʻia me nā mea hana sanwī kuʻuna meli, ʻoi aku ka kiʻekiʻe o ka hana ʻoi aku ka maikaʻi o ka honeycomb foam hou, a lanakila i nā hemahema o ka anisotropy o ka mea honeycomb sandwich. Ma ka hoʻololi ʻana i nā mea hana sanwī honeycomb pipiʻi me nā mea alumini foam hou, hiki ke hoʻemi nui ʻia ke kumukūʻai i ka wā e loaʻa ai ka hana kiʻekiʻe. I loko o ka ʻoihana kūkulu hale, hiki ke hana ʻia ka pahu alumini a i ʻole nā ​​​​mea hao ʻē aʻe i māmā, paʻa, nā mea pale ahi, railings a i ʻole kākoʻo, e like me nā elevators hou me ka wikiwiki a me ka wikiwiki kiʻekiʻe a me ka deceleration. -e hoʻopaʻa ʻana a me ka lawe ʻana i nā waiwai o nā mea metala foam māmā e hōʻemi i ka hoʻohana ʻana i ka ikehu.
Ke hoʻohālikelike ʻia me nā mea metala paʻa, hiki ke hoʻohana ʻia ka pahu alumini mau mea hou e like me nā mea hana a me nā mea hana, ʻoiai ma ke ʻano nui o ka pahu alumini mau mea hou he mau hana a me ke ʻano hana, a paʻa a maʻalahi hoʻi e hana hou, e lilo ia i mea manaʻo nui no ka ʻoihana. pūʻali koa, aerospace a me nā noi kūkulu.
