Mīhini Kārihini Kua Tapahia vs Mīhini Tūturu: Ngā Rerekē Matua o te Mahi

Kua whakangahau te whakapakari i te mātā a karbona i te hangaranga o nāianei i roto i ngā umanga, mai i te noho ki te atamira ki ngā tono motuka. I roto i ngā āhuatanga maha e wātea ana mō ngā matā a karbona, ko te mātauranga i ngā rerekētanga takotoranga kei waenganui i te matā a karbona kīato me ngā pūnaha matā tōpū e hiahiatia ana mō ngā inijiniara me ngā kaihanga. Ko te whiriwhiri i waenganui i ēnei tuarangi whakapakari e rua e pa tūwārite ana ki te mahinga o te hua, ki ngā tikanga hangaranga, me ngā utu o te kaupapa anuanu. Kātahi ka tirohia tēnei tātaritanga whānui i ngā rerekētanga mahi matua e āwhina ana i ngā whiringa matā i te ao hangaranga whawhai anuanu o nāianei.

Ngā Āhuatanga Mahi Tōpū

Ngā Taputapu Manawa

Ko ngā rerekētanga o te kaha mekameka i waenganui i ngā huinga mātātoko karboni me ngā huinga aha aha e tohu ana pea i te rerekētanga mahinga nui rawa. Ko te mātātoko karboni aha aha e mau ana i ngā ara uta e kore e mutu i roto i te hanganga composite, e āwhina ana i ngā kaha tōkei tōkei e piki ake ana i te 3,500 MPa i ngā whakamahinga tikangia. Ka taea e tēnei tūhuratanga aha aha te tuku kaha ki te roa katoa o te mātātoko, ka nui ake ai ngā taputapu kaha takotoranga o te matā. Ko te whakaritenga mātātoko ārahi hoki i ngā huinga aha aha e tuku ana i ngā āhuatanga kaha āhuatanga e mōhiotia ana e ngā inije, ā, e taea ana te whakamahi mō ngā herekore herekore motuhake.

He tōtika, ko ngā punonga mīhini kihini kākahu he iti ake te rereketanga o te kaha nā te āhuatanga hāpōturi. Ahakoa kei te pūmau tonu te kaha a ia wāhanga kihini, ko te kaha o te composite katoa e noho pā ki te roa o te kihini, te tohatoha o te āhuatanga, me te hononga i waenganui i te matrix me te kihini. Ko te kaha tāwhai a te mīhini kihini kākahu e eke ana i te 200-800 MPa, he iti ake tēnei i ngā punonga tūtonu engari he nui tonu anō ngā whanaketanga ki ngā matapae tawhito. Ko te āhuatanga tūtohu o ngā kihini i ētahi mīhini kākahu e tuku ana i ngā taputapu kaha ōrite, he pai mō ngā whakamahinga e here ana ki te manaaki i ngā tāpoi mai i ngā taha maha.

Ngā Whakaaro mō te Matotoru me te Mōhini

He rerekē te mahi ake o te īmōhini pākihi i waenganui i ngā punaha whakakī arotini karbona tūturu me ngā takotoranga kua tapahia. Ka taea e ngā composite arotini te eke ki ngā uara īmōhini e pānuitia ana i runga ake i te 200 GPa ina taruaruatia ngā arotini ki ngā tātai tuku kōkiri matua. Ko te hihiri tino pai nei ka whakarite ai i ngā punaha tūturu hei mea pai mō ngā whakamahi e here ana ki te itinga iti i raro i te wero, pērā i ngā hanganga rererangi me ngā wae wae tapahi tikangia.
