ʻO ka hana kiʻekiʻe o nā mea carbon fiber e loaʻa iā ia kahi hana noi kiʻekiʻe loa i nā ʻoihana he nui.Kekalapona kalaponahoʻohana ʻia ka huahana, ʻike ʻia he kiʻekiʻe ke kumukūʻai holoʻokoʻa.ʻO kahi kahi i kiʻekiʻe ai ke kumukūʻai o ka huahana fiber haʻihaʻi e pili ana i nā wahi he nui.E haʻi aku kā mākou hui iā ʻoe mai ka hiʻohiʻona o ka fiber carbon.
ʻO nā huahana fiber carbon a mākou e ʻike ai he ʻokoʻa loa ia mai kā mākou mau mea kalapona kalapona, no ka mea, ʻaʻole hiki ke hana wale ʻia nā fibers, a pono e hui pū ʻia me ka resin matrix e hoʻopau i ka hana ʻana o nā huahana.ʻO kekahi kumu ke kumu kūʻai nui ʻana o ke kumukūʻai o nā huahana fiber, ʻo ia ke kiʻekiʻe o ke kumukūʻai o nā filament carbon, no laila pono mākou e hoʻomaopopo mua i ka mea hao kalapona.
ʻEkolu ʻano o ke kaʻa kaʻa haʻihaʻi, me ka polyacrylonitrile (PAN)-based carbon fiber, pitch-based carbon fiber and gum-based carbon fiber.ʻO ka mea maʻamau o ka PAN-based carbon fiber ka mea maʻamau, a ʻoi aku ka nui o ka mākeke holoʻokoʻa ma luna o 90%, no laila ʻo ka thermoplastic carbon fiber o kēia manawa pili i ka PAN-based carbon fiber.
Ua hana ʻia ʻo Polyacrylonitrile i ka hoʻomaka.Ua hana ʻia e Akio Kondo ma Iapana i ka makahiki 1959, a laila hana nui ʻia ma Toray i ka makahiki 1970. ʻO ka polyacrylonitrile carbon filament holoʻokoʻa he ikaika kiʻekiʻe loa a me nā hiʻohiʻona o kahi hōkū hoʻohālike.Ua hoʻomohala ʻia ka fiber e pili ana i ka asphalt e ke Kulanui ʻo Gunma ma Iapana i ka makahiki 1965. He kiʻekiʻe loa ka conductivity thermal o kēia carbon fiber tow e like me 90OGPa, no laila ua hoʻohana nui ʻia i nā mea hana kūikawā.Ua hoʻohana nui ʻia ka fiber kalapona Viscose ma ke ʻano he mea hoʻohui no nā pale wela o ka mokulele i nā makahiki 1950, a ʻo ia hoʻi ka mea e hoʻohana ʻia i kēia manawa.No laila ua ʻike mākou ua hana ʻia nā mea mua ʻelua e ka poʻe Kepanī, ʻo ia ke kumu i hoʻokumu ʻia ai ke ana o ke ana hana o ke kalapona kalapona i ka Toray carbon fiber material.
ʻOiaʻiʻo, ua hoʻomau ka holomua o ka noiʻi a me ka hoʻomohala ʻana o ka carbon fiber tow precursors i nā makahiki i hala iho nei, akā ʻaʻole i hoʻokō ka hopena holoʻokoʻa.I kēia mau lā, ʻo PAN ka mea nui.I ka hana ʻana i nā filament kalapona, hiki i ka hua kalapona o nā precursors ʻekolu ke piʻi ma mua o B80%.ʻO ka manaʻo, e emi loa ke kumukūʻai o ia mau filament carbon fiber, akā pono e hoʻomaʻemaʻe a hoʻololi ʻia ka hana ʻana o ka pitch-based.ʻO kēia kaʻina hana e hoʻonui nui i nā kumukūʻai hana a hoʻemi i ka hua i 30%.No laila ʻoi aku ka kaulana o nā mea PAN.
No laila, e nānā kākou i ka fiber carbon PAN i hoʻohana nui ʻia.ʻOi aku ka haʻahaʻa o ke kumu kūʻai o ka fiber carbon-based PAN ma mua o ke kumu o ka fiber carbon-based asphalt, a hiki ke hoʻohana ʻia i nā kula he nui.ʻO ke kumu kūʻai o ka fiber PAN-based no nā satelite he kiʻekiʻe e like me 200 yen/kg, aʻo ke kumu kūʻai o ka fiber carbon no nā kaʻa he haʻahaʻa e like me 2,000 yen/kg.
A laila hoʻohana mau mākou i ke kumu o ka carbon fiber a Toray.Maʻaneʻi, ua hoʻokaʻawaleʻia nā PAN-based fibers i nā kaʻa nui a me ka liʻiliʻi.No ka laʻana, ʻo ke kumukūʻai o ka 3K maʻamau he 50-70 US kālā / kg, a ʻo ke kumukūʻai o 6K he 4-50 US kālā/kg.No laila, hiki iā mākou ke hoʻomaopopo i ke kumu e hoʻohana nui ʻia ai nā tow liʻiliʻi i nā kula kiʻekiʻe.
No laila, ke ʻōlelo nei mākou e ʻoi aku ka maikaʻi o ke kumukūʻai o ka fiber carbon.ʻAʻole ia he kumu ʻole ka nui o ka hana me nā mea maka.Eia kekahi, he mea kiʻekiʻe ke kumukūʻai o nā huahana carbon fiber, a he mea nui ia e pili ana i ka pono o kā mākou huahana carbon fiber e koi nui i ka hana a me nā mea hana.
