Nā pōmaikaʻi o ke kaula conductive carbon fiber

I ka wā e pili ana i nā uea, manaʻo mua mākou i nā uea keleawe, nā uea alumini, nā uea hao a me nā uea metala ʻē aʻe.Hana ʻia lākou a pau i ke kaha uea metala maʻemaʻe.ʻO ke kumu o ka hoʻohana ʻia ʻana o nā metala ʻo ia ka maikaʻi o nā metala a pau.ʻO ke kumu i loaʻa ai ka conductivity uila maikaʻi o nā metala no ka mea ʻoi aku ka liʻiliʻi o nā electrons waho o nā ʻātoma metala.Ma hope o ka hoʻohui ʻia ʻana i mau pūʻulu ʻātoma, ʻo ka papa waho o kēlā me kēia atom he hoʻokahi wale nō a ʻelua mau electrons a kaʻapuni a puni ia, no laila hoʻokahi a ʻelua mau electron wale nō ka papa waho o ka atom.E nui aʻe nā hakahaka electron ma ka papa, no laila hiki i nā electron haole ke komo maʻalahi a neʻe, a maʻalahi ka metala e hoʻokele uila, no laila ʻo nā uea a mākou i ʻike ai he metala maoli.
Ma muli o ka conductivity maikaʻi o ka metala, nā uea o kēia manawa he metala maoli.Hiki ke hoʻololi ʻia nā uea e nā mea pili ʻole?Hiki nō hoʻi, e like me ka fiber carbon.
Ua ʻike nā hoaaloha he ʻoi loa ka paʻakikī o ka fiber carbon, akā ʻaʻole lākou i ʻike he conductive kekahi mau fiber carbon.ʻO ia ke kumu no ka loaʻa ʻana o ia mau fibers i kahi ʻano atomic e like me ka graphite, a ʻo ka graphite he mea alakaʻi maikaʻi, ʻo ia ke ʻano o ka mea kalapona.Allotropes, ua hoʻohui ʻia kēlā me kēia kalapona kalapona i loko o ka graphite me ʻekolu mau kalapona kalapona ʻē aʻe a puni ia, i hoʻonohonoho ʻia i loko o kahi ʻano hexagonal honeycomb-like, kahi e hoʻokuʻu ai kēlā me kēia kalapona kalapona i kahi electron manuahi, no laila ke alakaʻi nei ka graphite i ka uila.He maikaʻi loa ka hana, ma kahi o 100 mau manawa kiʻekiʻe ma mua o nā mea metala maʻamau.
Eia nō naʻe, ʻaʻole i hilinaʻi ka conduction o kēia manawa i loko o ka uea carbon fiber composite ma luna o ka pulupulu kalapona, no ka mea, ʻaʻole maikaʻi ka conductivity o ka pulupulu kalapona.Hoʻohui ka resin i nā filaments kalapona i hoʻonohonoho lōʻihi ʻia i loko o kahi holoʻokoʻa, i mea e emi ai ka conductive o ke kalapona kalapona, no laila ʻaʻole hoʻohana ʻia ke kalapona kalapona ma ʻaneʻi no ka hoʻokele uila, akā no ke kaumaha.ʻO ke ʻano o ka uea kumu hoʻohuihui kalapona ua like ia me ka uea alumini i hoʻopaʻa ʻia.Hoʻokaʻawale ʻia ʻo ia i ka uea i loko a me ka uea alumini ʻili.ʻO ka uea koʻikoʻi e halihali i ka hapa nui o ke koʻikoʻi mechanical o ka uea ponoʻī, aʻo ka uea alumini waho e lawe i ka hana kahe o kēia manawa.
ʻIke ʻia ʻo nā uea haʻahaʻa i loko o nā uea he mau kaula kila, maʻamau nā kaula wili kila i wili ʻia mai 7 mau kaula hao, a ʻo waho he uea alumini i haku ʻia me nā kakini o nā kaula alumini, akā ʻo ka carbon fiber composite. ʻO ka uea maʻamau he kaula waena o nā mea i hui pū ʻia ka fiber carbon, a ʻo waho he quadrilateral.ʻO ka uea alumini kaʻa nui, e like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, ʻo ka hema ka uea alumini kila, a ʻo ka ʻākau ka uea kumu hoʻohuihui kalapona.
Ua ʻike mākou ʻoiai ʻo ke kila ka ikaika tensile maikaʻi a me ka paʻakikī, ʻoi aku ka nui o kona mānoanoa, no laila ua kaumaha loa, akā ʻoi aku ka liʻiliʻi o ka nui o ka carbon fiber composite material, ʻo 1/4 wale nō o ke kila, a ʻo kona kaumaha like wale nō. leo nui.Eia nō naʻe, ʻoi aku ka maikaʻi o ka ikaika tensile a me ka paʻakikī o ka carbon fiber ma mua o ke kila, ʻoi aku ka liʻiliʻi ma ka liʻiliʻi ʻelua o ka ikaika tensile o ke kila, no laila ke kumu nui o ka hoʻohana ʻana i ka carbon fiber composite mea e hōʻemi i ke kaumaha o ke kaula, a me ka mānoanoa like. no ka ʻoi aku o ka maikaʻi o ka huki ʻana, hiki iā ia ke lawe i ka uea alumini hou, e ʻoi aku ka mānoanoa o ka uea a i ʻole ke kaula e hele i kēia manawa.
No ka mea ua loaʻa i ka uea carbon fiber composite nā waiwai maikaʻi i ʻōlelo ʻia ma luna nei o ka haʻahaʻa haʻahaʻa, ke kaumaha māmā, ka ikaika tensile nui a me ka paʻakikī ikaika, inā hiki ke hoʻohana ʻia kēia mea no ka manawa lōʻihi, hiki ke hoʻololi i ka uea kila a me ka uea alumini. i ka wā e hiki mai.ʻO ka uea maʻamau i hoʻohana ʻia, a ʻo ka uea carbon fiber he hopena hoʻomehana ke hoʻoikaika ʻia, no laila e hoʻohana ʻia ʻo ia ma ke ʻano he uea wela i kekahi mau ʻoihana.No laila, ʻaʻole pono ka uea o kēia manawa he metala, a ʻo ka uea non-metallic e lilo hou a ʻike pinepine ʻia.
