Mīkini wili kalaponahe kūlana kiʻekiʻemīkini wilihuahana o kēia pūʻulu mīkini wili.Ke hoʻohālikelike ʻia me nā mea ulana kuʻuna e like me ke kaula pulupulu a me ka uea metala, ʻoi aku ka kiʻekiʻe o ka mīkini wili carbon fiber i nā koi ʻenehana a ʻoi aku ka paʻakikī o ka hoʻolālā a me ka hana ʻana.
Eia nō naʻe, ʻaʻole hiki ke hōʻole ʻia ke hoʻohālikelike ʻia me nā mea ulana kuʻuna, he mau hiʻohiʻona maikaʻi loa ka ulana kalapona, a he ākea kona mau noi e hiki mai ana.ʻO kēia kekahi o nā kumu i hana mau ai ʻo Benfa Technology i ka ʻenehana ulana fiber carbon i kahi kuhikuhi holomua nui.
Ke hoʻohālikelike ʻia me nā mea ulana kuʻuna, he aha nā ʻano o nā mea fiber carbon?
1. Ka ikaika tensile ikaika
ʻO ka ikaika tensile o ka fiber carbon ma kahi o 2 a 7 GPa, a ʻo ka modulus tensile ma kahi o 200 a 700 GPa.ʻO ka mānoanoa ma kahi o 1.5 a 2.0 grams no ka cubic centimeter, ka mea i hoʻoholo nui ʻia e ka mahana o ke kaʻina carbonization i hoʻohui ʻia i ke ʻano o ka siliki kumu.ʻO ka maʻamau ma hope o ka mālama ʻana i ka graphitization kiʻekiʻe kiʻekiʻe 3000 ℃, hiki i ka nui ke hiki i 2.0 grams no ke kenimika cubic.Eia kekahi, he māmā loa kona kaumaha,ʻoi aku ka māmā o kona'umekaumaha ma mua o ka alumini, emi iho ma mua o ka 1/4 o ke kila, aʻo kona ikaika kūikawā he 20 manawa o ka hao.ʻOkoʻa ka helu hoʻonui wela o ka fiber carbon mai nā fibers ʻē aʻe, a loaʻa iā ia nā ʻano anisotropy.
2. Li'ili'i ho'onui wela wela
ʻO ke koena hoʻonui wela o ka hapa nui o ke kalapona ponoʻī he maikaʻi ʻole i loko o ka hale (-0.5 ~ -1.6) × 10-6/K, ʻaʻole ia ma 200-400 ℃, a me 1.5 × 10-6/K ke emi iho ma mua o 1000 ℃ .ʻO ka mea hoʻohuihui i hana ʻia me ia he mea hoʻonui paʻa paʻa a hiki ke hoʻohana ʻia ma ke ʻano he mea kaupaona maʻamau.
3. maikaʻi thermal conductivity
ʻO ka mea maʻamau, ʻilihune ka conductivity thermal o nā mea inorganic a me nā mea kūlohelohe, akā ʻo ka conductivity thermal o ka carbon fiber kokoke i ke kila.Ma ka hoʻohana ʻana i kēia pono, hiki ke hoʻohana ʻia ma ke ʻano he mea no nā mea hōʻiliʻili wela o ka lā a me kahi mea hoʻokele wela me ka hoʻoili wela like ʻole.
4. palupalu a me ka processability
Ma waho aʻe o nā hiʻohiʻona o nā mea kalapona maʻamau, ʻo nā lole i ulana ʻia ke kalapona he palupalu anisotropic koʻikoʻi i ka helehelena a hiki ke hana ʻia i nā lole like ʻole.Ma muli o ko lākou ʻumekaumaha liʻiliʻi, hōʻike lākou i ka ikaika kiʻekiʻe ma ka axis fiber.ʻO nā apo i hoʻopaʻa ʻia i ka carbon fiber o ka Oxygen resin composite nā mea hōʻailona kiʻekiʻe loa o ka ikaika kūikawā a me ka modulus kikoʻī i waena o nā mea hana.
5. Ke pale wela haʻahaʻa
He maikaʻi ke kūpaʻa haʻahaʻa haʻahaʻa o ka fiber carbon, e like me ka brittle ma lalo o ka mahana wela o ka wai.
6. Ke kū'ē i ka corrosion
Loaʻa i ka carbon fiber ke kūpaʻa ʻino maikaʻi i nā mea hoʻoheheʻe organik maʻamau, nā waikawa, a me nā alkalis.ʻAʻole ia e hoʻoheheʻe a pehu.Loaʻa iā ia ka pale corrosion koʻikoʻi a ʻaʻohe pilikia o ka ʻōpala.
7. ʻAʻahu maikaʻi ke kūpaʻa
ʻAʻole hiki ke hoʻohana ʻia ke kalapona kalapona a me ka metala i ka wā e hamo ai kekahi i kekahi.Hoʻohana ʻia ka carbon fiber e pani i ka asbestos no ka hana ʻana i nā mea friction kiʻekiʻe, i hoʻohana ʻia e like me nā mea pale pahu no nā mokulele a me nā kaʻa.
8. ʻO ke kūpaʻa wela kiʻekiʻe maikaʻi
Paʻa loa ka hana o ke kalapona kalapona ma lalo o 400°C, a ʻaʻole nui ka loli ma 1000°C.ʻO ke kūpaʻa wela kiʻekiʻe o nā mea hoʻohuihui e hilinaʻi nui ʻia i ka pale wela o ka matrix.ʻO ke kūpaʻa wela lōʻihi o ka resin-based composite material ma kahi o 300 ℃ wale nō, a ʻo ke kūpaʻa wela kiʻekiʻe o ka ceramic-based, carbon-based a me metala-based composite mea hiki ke hoʻohālikelike i ka carbon fiber ponoʻī.Hoʻohana nui ʻia nā mea hoʻohuihui carbon fiber i ka ʻoihana aerospace e like me nā mea pale wela kiʻekiʻe.
9. Maikaʻi maikaʻi
He maikaʻi maikaʻi ka fiber carbon (ʻo kekahi o nā hiʻohiʻona o ka maikaʻi ʻo ka helu o nā grams o kahi fiber 9000-mika-lōʻihi), maʻamau ma kahi o 19 grams wale nō, a me ka ikaika tensile a hiki i 300 kg no ka micron.Kakaʻikahi nā mea ʻē aʻe i loaʻa nā waiwai maikaʻi loa e like me ka fiber carbon.
10. Ke kū'ē i ka hopena maikaʻiʻole a maʻalahi ka pōʻino
Hana ʻia ka oxidation ma lalo o ka hana a ka waika ikaika, maikaʻi ka ikaika electromotive o ke kalapona kalapona, a ʻo ka ikaika electromotive o ka alumini alumini he maikaʻi ʻole.Ke hoʻohana ʻia nā mea hoʻohuihui carbon fiber i hui pū ʻia me nā alumini alumini, e hiki mai ana ka carbonization metala, carburization a me ka corrosion electrochemical.No laila, pono e mālama ʻia ka fiber carbon ma mua o ka hoʻohana ʻana.
