1. He aha te taura muka whatu FRP?
FRPka taea hoki te kōrero mō te pūmua whakapakari muka e whakamahia ana i roto i ngā taura muka whatu. He mea hanga ngā taura muka whatu ki ngā muka karāhe, ki ngā muka kirihou rānei e tuku raraunga ana mā te whakamahi i ngā tohu mārama. Hei tiaki i ngā muka pakarukaru me te whakarato i te kaha ā-ringa, he maha ngā wā ka whakapakarihia ki tētahi mema kaha pokapū i hangaia ki te pūmua whakapakari muka (FRP) me te maitai rānei.
2. Me pēhea te FRP?
Ko te FRP he whakarāpopototanga mō te Fiber Reinforced Polymer, ā, he momo rauemi hiato e whakamahia whānuitia ana i roto i ngā taura muka whatu hei mema kaha. Ka tautoko te FRP i te taura, e āwhina ana ki te ārai i te kino o ngā miro muka whatu ngawari i roto i te taura. He rauemi ātaahua te FRP mō te taura muka whatu nā te mea he kaha, he māmā, ā, he ātete ki te waikura me ētahi atu āhuatanga taiao. Ka taea hoki te hanga ngāwari ki ngā āhua me ngā rahi rerekē, kia urutau ai ki te whānuitanga o ngā hoahoa taura.
3. Ngā Painga o te Whakamahi i te FRP i roto i ngā Taura muka whatu
He maha ngā painga o te FRP (Forum Whakakaha Muka) mō ngā tono taura muka.
3.1 Kaha
Ko te mātotorutanga o te FRP kei waenga i te 1.5 ki te 2.0, he hauwhā ki te haurima noa iho o te maitai waro. Ahakoa tēnei, he rite tonu tōna kaha kume ki te maitai waro, he nui ake rānei. Hei tāpiri, ka taea te whakarite i tōna kaha motuhake ki te maitai koranu kounga teitei. He kaha me te pakari te FRP, ā, he rauemi pai mō ngā mema kaha taura. Ka taea e ia te whakarato i te tautoko e tika ana hei tiaki i ngā taura muka mai i ngā kaha o waho me te ārai i te kino.
3.2 Mama
He mama ake te FRP i te maitai, i ētahi atu konganuku rānei, ā, ka taea e tēnei te whakaiti i te taumaha o te taura muka. Hei tauira, ko te taumaha o te taura maitai noa he 0.3-0.4 pauna ia putu, ko te taumaha o te taura FRP ōrite he 0.1-0.2 pauna ia putu. Mā tēnei ka māmā ake te whakahaere, te kawe, me te tāuta i te taura, inā koa i ngā mahi ā-rangi, i ngā mahi whakairi rānei.
3.3 Ātete ki te waikura
He ātete te FRP ki te waikura, he mea tino nui tēnei i roto i ngā taiao uaua, pērā i te moana, i raro rānei i te whenua. Ka taea e ia te āwhina ki te tiaki i te taura muka mai i te kino, me te whakaroa i tōna roanga ora. I roto i tētahi rangahau i whakaputaina i roto i te Journal of Composites for Construction, ko ngā tauira FRP i tukuna ki ngā taiao moana uaua i whakaatu i te iti o te kino i muri i te wā whakaaturanga 20-tau.
3.4 Kore-arahi
He rauemi kore-arahi hiko te FRP, arā, ka taea e ia te whakarato i te ārai hiko mō te taura muka. He mea nui tēnei i roto i ngā tono ka pāngia te mahi a te taura muka e te pokanoa hiko.
3.5 Ngāwari o te Hoahoa
Ka taea te hanga i te FRP ki ngā āhua me ngā rahi rerekē, ka taea ai te whakarite i ngā hoahoa me ngā whirihoranga taura. Ka āwhina tēnei ki te whakapai ake i te whai huatanga me te mahi a te taura muka.
4. Ngā Mema Kaha FRP vs. Ngā Mema Kaha Rino vs. KFRP i roto i te Taura Muka Whatu
E toru ngā rauemi e whakamahia whānuitia ana mō ngā mema kaha o ngā taura muka whatu ko te FRP (Fiber Reinforced Plastic), te maitai, me te KFRP (Kevlar Fiber Reinforced Plastic). Me whakarite ēnei rauemi i runga i ō rātou āhuatanga me ngā āhuatanga.
4.1 Te Kaha me te Pūmau
FRP: He mea hanga ngā mema kaha FRP mai i ngā rauemi hiato pēnei i te karāhe, i ngā muka waro rānei kua whakauruhia ki roto i te anga kirihou. He kaha kume pai, he mama hoki, ā, he pai mō ngā whakaurunga ā-rangi. He ātete hoki ki te waikura me ngā matū, ā, he pakari i roto i ngā taiao uaua.
Rino: E mōhiotia ana ngā wāhanga pakari o te rino mō tōna kaha kume teitei me tōna roa o te mau. He maha ngā wā ka whakamahia i roto i ngā whakaurunga o waho e hiahiatia ana te kaha miihini teitei, ā, ka taea e rātou te tu atu i ngā āhuatanga o te rangi kino. Heoi, he taumaha te rino, ā, ka ngāwari ki te waikura i roto i te wā, ka pā pea ki tōna roa o te ora.
KFRP: He mea hanga ngā mema kaha o te KFRP ki ngā muka Kevlar kua whakauruhia ki roto i tētahi anga kirihou. E mōhiotia ana a Kevlar mō tōna kaha me tōna pakari tino pai, ā, he kaha kume teitei ngā mema kaha o te KFRP me te iti o te taumaha. He ātete hoki te KFRP ki te waikura me ngā matū, ā, he pai mō ngā whakaurunga o waho.
4.2 Ngāwari me te Māmā o te Tāutanga
FRP: He ngāwari te whakamahi i ngā wāhanga kaha FRP, ā, he pai mō te tāutanga i ngā wāhi kuiti, i ngā āhuatanga rānei e hiahiatia ana te ngāwari. Ka taea te piko, te hanga rānei kia uru ki ngā momo āhuatanga tāutanga.
Rino: He pakari, he iti ake te ngāwari o ngā wāhanga pakari rino ki te FRP me te KFRP. Tērā pea ka hiahiatia he taputapu tāpiri hei piko, hei hanga rānei i te wā e tāuta ana, ka nui ake te uaua me te roa o te tāutanga.
KFRP: He tino ngāwari, he ngāwari hoki te pupuri i ngā mema kaha o te KFRP, he rite ki te FRP. Ka taea te piko, te hanga rānei i te wā tāutanga me te kore e hiahiatia he taputapu tāpiri, kia watea ai mō ngā momo āhuatanga tāutanga.
4.3 Taumaha
FRP: He mama ngā wāhanga kaha FRP, ā, ka āwhina i te whakaiti i te taumaha katoa o te taura taka muka whatu. Nā tēnei ka pai mō ngā whakaurunga ā-rangi me ngā āhuatanga e whakaarohia ana te taumaha, pērā i ngā tono o runga.
Rino: He taumaha ngā wāhanga pakari o te rino, ka taea e tēnei te tāpiri taumaha ki te taura taka muka whatu. Kāore pea tēnei i te pai mō ngā whakaurunga ā-rangi, mō ngā āhuatanga rānei me whakaiti te taumaha.
KFRP: He mama ngā mema kaha o te KFRP, he rite ki te FRP, ā, ka āwhina i te whakaiti i te taumaha katoa o te taura taka muka whatu. Nā tēnei ka pai mō ngā whakaurunga ā-rangi me ngā āhuatanga e whai whakaaro nui ana ki te taumaha.
4.4 Te Arahi Hiko
FRP: Kāore ngā mema kaha FRP e kawe hiko, ā, ka taea e tēnei te whakarato i te wehenga hiko mō ngā taura muka whatu. He painga tēnei i ngā wā e tika ana kia whakaitihia te pokanoa hiko.
Rino: He ara hiko hiko ngā wāhanga kaha o te rino, ā, ka tūpono pea tēnei ki te pokanoa hiko, ki ngā raruraru whenua rānei i roto i ētahi tāutanga.
KFRP: Kāore hoki ngā mema kaha o te KFRP e kawe hiko, he rite ki te FRP, ka taea te whakarato i te wehenga hiko mō ngā taura muka whatu.
4.5 Te utu
FRP: Ko ngā mema kaha FRP he iti ake te utu i te maitai, ā, he pai ake te utu mō ngā tono taura taka muka whatu.
Rino: Ka nui ake te utu o ngā mema kaha o te rino ki te whakaritea ki te FRP, ki te KFRP rānei nā te utu o te rauemi me ngā tukanga hanga taapiri e hiahiatia ana.
KFRP: Tērā pea he nui ake te utu o ngā mema kaha o te KFRP i te FRP, engari he iti ake te utu ki te whakaritea ki te maitai. Heoi anō, ka rerekē pea te utu i runga i te kaihanga me te wāhi.
5.Whakarāpopototanga
Ka whakakotahi te FRP i te kaha teitei, te taumaha iti, te ātete ki te waikura, me te whakamarumaru hiko—he kōwhiringa pono mō te whakakaha taura muka whatu.AO KOTAHI, ka tukuna e mātou he FRP kounga teitei me te whānuitanga katoa o ngā rauemi mata taura hei tautoko i tāu mahi whakaputa.
