ʻEhia ka nui o ka wela kiʻekiʻe e hiki ke kū i ke kalapona kalapona, no ke aha ka nui o nā huahana kalapona i kū ʻole i ka wela kiʻekiʻe

Pehea ke kiʻekiʻe o ka wela e hiki ai ke kū i ke kalapona kalapona
ʻO ka pulupulu kalapona ponoʻī he kiʻekiʻe loa ke kūpaʻa wela, a hiki ke ʻōlelo ʻia he mea pale wela kiʻekiʻe loa, akā hilinaʻi nā mea hoʻohuihui kalapona i ka mea matrix.
Hoʻopuka ʻo Yan F cone i nā mea maka mai ka ʻaila a me ka lanahu.ʻO ka mua, lawe ʻia ka polyacrylonitrile, a laila lawe ʻia ka fiber carbon ma o polyacrylonitrile.ʻO nā koi ʻenehana ma aneʻi he kiʻekiʻe loa, a ʻo ka oxidation, carbonization a me ka graphitization i ke kaʻina holoʻokoʻa a pau e pono ai ka wela kiʻekiʻe e hoʻopau ai, ʻoi aku ma lalo o ke kiʻekiʻe o ke kiʻekiʻe o nā tausani degere o ka quarrying pōhaku, ma hope o ka wehe ʻana i ka makasina, ke kalaiwa kalapona. Loaʻa ka loaʻa ʻana, no laila, ʻoi aku ka kiʻekiʻe o ka wela o ka carbon fiber, hiki ke kū i ke kiʻekiʻe kiʻekiʻe o 3000 ℃, a hiki ke mālama i kahi pono hana maikaʻi.
No ke aha ka nui o nā huahana carbon fiber i kū ʻole i ka wela kiʻekiʻe?
E like me ka mea i ʻōlelo ʻia ma luna nei, ʻoi aku ka maikaʻi a me ke kūpaʻa kiʻekiʻe o ka carbon fiber.I ka hana ʻana i nā huahana carbon fiber, ʻaʻole ia he mea pono o ka fiber carbon.Pono pū kekahi mea matrix e hoʻopau i ka hana ʻana i nā huahana fiber hope loa.Kūleʻa nā huahana carbon fiber i nā wela kiʻekiʻe.E noʻonoʻo i ka pale wela kiʻekiʻe o ka mea kumu.
ʻO ka ʻoiaʻiʻo o ka nui o nā huahana carbon fiber ʻaʻole e wrinkle a wela no ka mea ʻo ka carbon fiber composite material ka hapa nui o ka carbon fiber + resin-based composite material, a ʻo ka ʻike o ka hope fiber tow i ka composite material ma kahi o 40% -45%, no laila. hana ʻO ke kūpaʻa wela kiʻekiʻe o nā huahana carbon fiber i hoʻopau ʻia e pili ana i ka pale wela kiʻekiʻe o ka resin.Ua like keia me ka loina o na barela laau.Ua lilo ka palena kiʻekiʻe o ka wela o ka resin i ka palena kiʻekiʻe o ke kūpaʻa wela kiʻekiʻe o nā huahana carbon fiber.
Ma lalo o nā kūlana maʻamau, ʻo ke kūpaʻa wela kiʻekiʻe o ka resin matrix ma kahi o 180C.Inā ʻoi aku ka lōʻihi o kēia mahana, e hoʻoheheʻe ʻia ka resin matrix, e hoʻopilikia i ka hana hope o ka huahana.
Eia kekahi, i mea e hoʻomaikaʻi hou ai i ka pale wela kiʻekiʻe, e koho ke kumu manamana lāʻau i kahi matrix me ke kūpaʻa kiʻekiʻe kiʻekiʻe, ʻo ia hoʻi, kahi plastic kūikawā.Inā loaʻa iā ʻoe kahi mea matrix me nā pono hana kiʻekiʻe e like me PEK a me PPS, a laila kūʻē nā huahana carbon fiber i hana ʻia i hiki ke piʻi ka mahana ma luna o 20YC.Inā makemake ʻia ke kūpaʻa ʻoi aʻe o ka mahana, pono e koho ʻia ka matrix metal-based carbon a i ʻole ceramic.Hiki ke ʻoi aku ka maikaʻi o ia ʻano pale wela kiʻekiʻe.
