Kei te hiahiatia haere tonu ana e ngā ahumahi whakawhanaketanga i te ao katoa ngā wāhanga mā, pūkaha hāngai e taea ai te tautohe me ngā tikanga āhuatanga ki te noho tonu i te utu-whaitua i ngā whanaketanga rahi-āhuatanga. Kua ara ake te tāraiwa puipui karboni hei tikanga whanaketanga e mōhiotia ana mō ngā wāhanga karboni puipui parahiko arataki i ngā kōtaha nui. Ko tēnei tikanga whanaketanga matatau e hono ana i ngā ahuatanga rerekē o te puipui karboni me ngā tikanga whanaketanga āhuatanga, he mea pai mō ngā mahi-aerorangi, motuka, tauranga-hanga, me ngā mahi tūmatanui i reira ko te mahi me te tautonotono te mea matua.
Te mārama ki te Tikanga Whanaketanga Tāraiwa Puipui Karboni
Ngā Mekanikia Matua o te Tikanga me te Rere o te Mātai
Ko te tikanga pultrusion e tīmata ana i te tōkina ake i ngā hiko haupapa karboni tonu ki roto i tētahi pāpā kua whakaputangia, i te wā e taraina ana rātou ki te punaha harauma kākano. Ko te tikanga hangarau tonu nei e tīmata ana ki ngā hiko karboni, ngā mātai, i ngā āhuā e tango ana i ngā kōpae, ka taraina ki roto i tētahi kōpae harauma, ki tētahi punaha inihini. Ka rere atu ngā hiko kua tarainahia ki tētahi tūranga arataki e āhua ana i te ahunga o te matēria kua mōhiotia kia tūhono ki te pāpā kua whakaputangia.
I roto i te pāpā, ka pā te harauma ki te whakaurunga whakahaerenga i raro i ngā tikanga wātea me te toki, e noho ana mai i te 300°F ki te 400°F e hāngai ana ki te punaha harauma. Ka puta tonu te kapa o te matēria kua oti te whakaputa mai i te pāpā, ka tōkina e tētahi punaha tōkina urutā ki ngā tere ōrite. E whakaae ana tēnei tikanga kia hangaia e ngā kaihangarau ngā waeonga karboni e āhua ana ki te pānga tino tika me ngā īnanga ōrite i te roa katoa.
Ko te Whakauru Kōpiko Resin me ng Āhuatanga Whakaputa
Ko te whiwhinga angitu o te pultrusion mātātoko karboni e hiahiatia ana te whiriwhiri tūmata tiaki, me te whakapai ake i ngā pūnaha resin kia taea ai te whakaputa tōtika i roto i te wā noho ki te pereki. Ka whakamahia noa ngā resin epoxy, polyester, me ngā vinyl ester, e tuku ana i ēnei anuanu motuhake mō ēnei tono motuhake. Me tuku te takotoranga resin i te wā mahi tino pai mō te parurenga arotini, ā, kia taea ai te āhuatanga whakaputa tere i raro i te whakapheatara, me te toki.
Ko ngā rārangi wera i roto i te pereki ka whakahaeratia tūmata ki te whakapaunga i te whakaputa whai muri mai i ng āhuatanga tāwāhi, ki te aukati i ngā wā koreumuumu ki roto, me te tiki i ng āhuatanga mekanik tāwhai.

FAQ
He aha ngā hautau matā o ngā tahumaero e taea te tiki mā te taraiwa karbon?
Ko te tāwhai arai karbona e piki ake ana i te 60% ki te 70% te hautau mōhio arai, he nui ake tēnei i ētahi atu tikanga hanga huinga. Ko te nui o ngā arai e hāngai ana ki ngā īnanga mekameka me te kounga ohooho. Mā te whakahaere tika i te tahumaero o ngā arai me te rere o te rēhinā i te tikanga tāwhai ka taea te hāngai tahi i ēnei hautau mōhio i te roanga o te huringa.
Pērāhea te tere huringa mātua ki ētahi atu tikanga hanga huinga?
Ko te tāwhai e tuku ana i te huringa ōrite i ngā tere e 12 ki te 60 inihi inia miniti, e hāngai ana ki te herenga o te wāhanga me ngā here o te whakaora. Ko tēnei e tohu ana i te anuanu hoki ake i ngā tikanga kotahi pēra i te takotoranga takotoranga, i te whakaora hauama rānei, e herea ana ngā wā huringa ki ngā haora engari kāore i te rere ōrite. Ko te āhuatanga ōrite e kore ai e noho wātea i ngā wā e utaina ana, e warma ana, me ngā wā e mātaratara ana e hāngai ana ki ētahi atu tikanga.
He aha ngā wāhi tōaitanga āhuatanga e taea ana e te tāwhai ake?
Ka taea e ngā wāhanga karbona parau te tāwhai kia eke ki ngā wāhi tōaitanga āhuatanga i waenganui i ±0.005 ki te ±0.030 ineri, kia tokomaha ai te rahi me te ahunga o te wāhanga. Ka pupuri tēnei tōaitanga tere tonu i te roanga o ngā kaupapa whakaputa, nā te taiao ripa whakahaere me te punaha tā auto. Ko te tikanga tino tika e taea ana ka herekore te hiahia ki ngā mahi tuarua mātai, ka heke ai ngā utu katoa o te hanga.
Ka taea te hanga i ngā āhua anuanu huinga pito kia puta ai te tāwhai?
Āe, ka taea e te tāwhai te hanga i tētahi tauira whānui āhua huinga pito, tae atu ki ngā wāhanga rūma, ngā I-pou, ngā kēngi, ngā ara, me ngā pūtohu ritenga e rite ana ki ngā hiahia tono motuhake. Ka taea e te maroleketanga hoahoa ripa ngā inžiniera ki te whakapaipai i ngā huinga pito mō te marumaru hanganga, te heke i te taima, me ngā hiahia arataki, i te wā e pupuri ana i ngā painga o te whakaputa ōrite me te kounga tōaitanga.
