Ko te arai FRP tētahi tikanga whakahaere waikura noa, ā, he mea nui rawa atu hoki i roto i ngā hanganga ārai-waikura taumaha. I roto i ēnei, he whānuitia te whakamahinga o te FRP whakatakoto-ā-ringa nā te mea he māmā noa iho te whakahaere, he watea, he ngāwari hoki. Ka taea te kī ko te tikanga whakatakoto-ā-ringa te take o te neke atu i te 80% o te ōwehenga o te hanganga ārai-waikura FRP. Ko ngā "rauemi matua e toru" ko te kapia, te muka me te muka paura i roto i te FRP whakatakoto-ā-ringa ko ngā angaanga o te FRP, e tautoko ana i te kaha o te pūnaha FRP, ā, he wāhanga nui hoki o te whakatutuki i te pānga roa o te ārai-waikura o te FRP.

I runga i te rerekētanga o te taiao waikura me te reo, ka rerekē anō hoki ngā rauemi o roto o te FRP. Ko te whiriwhiri rauemi ā-ture i te wā hanga he mea nui hei whakarite kia taea e te hua FRP kua oti te urutau ki te taiao waikura me tōna roa. Nō reira, me whakatau te whiriwhiri i ngā rauemi whakapakari FRP i mua i te hanganga. Hei tauira, ko ngā rauemi whakapakari e tohuhia ana e te muka karāhe ngā rauemi muka tino noa, ka taea te ātete i te nuinga o te waikura waikawa; heoi, kāore e ātete ki te waikawa hauwaiwai me te waikura waikawa phosphoric wera. Whakamahia te polyester, te polypropylene me ētahi atu kakahu muka waro me te huruhuru hipi, ka taea hoki e koe te whiriwhiri ki te whakamahi i te rinena, i te kākahu kua whakakorea te hinu rānei, ā, ko ētahi hua FRP me ātete ki te waikura me te kawe hiko, ka taea e koe te whiriwhiri i ngā rauemi muka waro. I roto i te kupu poto, ko te whiriwhiri i te muka whakapakari FRP whakatakotoranga-ā-ringa he pūkenga me te mātauranga me mātau e te hangarau ārai-waikura me ngā kaihoahoa.

I roto i ngā hua FRP kua whakapirihia, ko te nuinga o ngā muka whakapakari he muka karāhe, ahakoa he kakahu, he huruhuru hipi, he miro rānei. Ko te take matua, hei tāpiri atu ki te utu, kei a ia anō hoki ngā āhuatanga pai e whai ake nei:
01 Ātete matū
Kāore ngā muka kakahu muka karāhe kore-waro e pirau, e poke, e memeha rānei. He ātete ki te nuinga o ngā waikawa engari ko te waikawa hauwai me te waikawa whākawa wera.
02 Pūmau te āhua
Kāore ngā miro muka karāhe e whakamahia ana hei hanga papanga karāhe e totoro, e mimiti rānei nā ngā huringa o ngā āhuatanga o te hau. Ko te roanga o te whakaroa i te whatinga he 3-4%. Ko te tauwehenga whānui wera raina toharite o te karāhe-E papatipu he 5.4 × 10-6 cm/cm/°C.
03 Mahi wera pai
He iti ake te tauwehenga whakawhanui wera o ngā papanga muka karāhe, ā, he nui ake te kawe wera. He tere ake te whakamarara o te wera o te muka karāhe i ngā muka asbestos, i ngā muka rauropi rānei.
04 Te kaha kume teitei
He nui te ōwehenga kaha-ki-taumaha o te miro muka karāhe. E rua te kaha o te pauna miro muka karāhe i te waea maitai. Mā te kaha ki te hanga i te kaha kotahi-ahunga, e rua-ahunga rānei ki roto i te papanga ka nui ake te ngāwari o ngā hua whakamutunga.
05 Te ātete wera nui
Kāore ngā muka karāhe kore-waro e mura, ā, he ātete ki ngā pāmahana tunu me te whakamaroke teitei e kitea ana i roto i ngā tukatuka ahumahi. Ka mau tonu te muka karāhe i te 50% o tōna kaha i te 700°F me te 25% i te 1000°F.
06 Te iti o te waikura
He mea hanga ngā miro muka karāhe ki ngā muka kore-pūangi, nō reira he iti rawa te mimiti makuku.
07 He pai te ārai hiko
Nā te kaha teitei o te parenga hiko me te iti o te pūmau parenga hiko, me te iti o te mimiti wai me te ātete ki te pāmahana teitei, he mea tino pai ngā papanga muka karāhe mō te whakamahana hiko.
08 Ngāwari o te hua
Ko ngā miro tino angiangi e whakamahia ana i roto i ngā miro muka karāhe, he maha ngā rahi me ngā whirihoranga o ngā miro, ngā momo raranga rerekē, me ngā whakaotinga motuhake maha, e whai hua ai ngā papanga muka karāhe mō ngā whakamahinga ahumahi maha.
09 utu iti utu iti
Ka taea e ngā papanga muka karāhe te mahi i te mahi, ā, he rite tonu te utu ki ngā papanga muka hangai me ngā muka taiao.

Nō reira, he rauemi whakakaha FRP tino pai te muka karāhe hei whakatakoto ā-ringa, he mea ohanga, he iti te utu, he ngāwari hoki te whakahaere. Ko tētahi o ngā rauemi e whakamahia whānuitia ana i roto i ngā rauemi whakakaha maha i tēnei wā.
