Ko te whanaketanga o te GFRP i ahu mai i te pikinga ake o te hiahia mō ngā rauemi hou he pai ake te mahi, he mama ake te taumaha, he ātete ake ki te waikura, ā, he pai ake te penapena pūngao. I te whanaketanga o te pūtaiao rauemi me te whakapai tonu i te hangarau hanga, kua piki haere te whānuitanga o ngā tono a te GFRP i roto i ngā mara rerekē. Ko te GFRP te nuinga o te wā hemuka karāheme te matihiko kapia. Ina koa, e toru ngā wāhanga o te GFRP: te muka karāhe, te matihiko kapia, me te kaiāwhina ā-kanohi. I roto i ēnei, he wāhanga nui te muka karāhe o te GFRP. Ka hangaia te muka karāhe mā te rewa me te kukume i te karāhe, ā, ko te wāhanga matua ko te hauhā silicon (SiO2). He painga ngā muka karāhe o te kaha teitei, te iti o te mātotoru, te wera, me te ātete ki te waikura hei whakarato i te kaha me te pakari ki te rauemi. Tuarua, ko te matihiko kapia te piripiri mō te GFRP. Ko ngā matihiko kapia e whakamahia whānuitia ana ko te polyester, te epoxy, me ngā kapia phenolic. He pai te piri o te matihiko kapia, te ātete matū, me te ātete pānga hei whakatika me te tiaki i te muka karāhe me te whakawhiti kawenga. I tetahi atu taha, he mahi nui tā ngā kaiāwhina ā-kanohi i waenga i te muka karāhe me te matihiko kapia. Ka taea e ngā kaiāwhina ā-kanohi te whakapai ake i te piri i waenga i te muka karāhe me te matihiko kapia, me te whakarei ake i ngā āhuatanga miihini me te roa o te GFRP.
Ko te hanganga ahumahi whānui o te GFRP me whai i ēnei mahi:
(1) Te whakarite muka karāhe:Ka whakamahanatia te karāhe, ka rewa, kātahi ka whakaritea kia puta he āhua me he rahi rerekē o te muka karāhe mā ngā tikanga pēnei i te tā, te rehu rānei.
(2) Te Whakaora i te muka karāhe:Te maimoatanga mata ā-tinana, ā-matū rānei o te muka karāhe hei whakanui ake i te taratara o te mata, hei whakapai ake hoki i te piri o te mata.
(3) Te whakaritenga o te muka karāhe:Tohatohahia te muka karāhe kua maimoatia i mua ki roto i te taputapu whakahāngai kia rite ki ngā whakaritenga hoahoa hei hanga i tētahi hanganga muka kua whakaritea i mua.
(4) Te hanganga kapia paninga:Pania te mata kapia ki runga i te muka karāhe kia ōrite, whakakīia ngā paihere muka, ka whakanoho i ngā muka kia pā katoa ki te mata kapia.
(5) Te whakamaroke:Te whakamaroke i te hanganga kapia mā te whakamahana, te pēhanga, te whakamahi rānei i ngā rauemi āwhina (hei tauira, te kaihoko whakamaroke) hei hanga i tētahi hanganga hiato kaha.
(6) Whai muri i te maimoatanga:Ka tukuna te GFRP kua rongoatia ki ngā tukanga whai muri i te maimoatanga pērā i te kuti, te oro, me te peita hei whakatutuki i ngā whakaritenga kounga me te āhua o te mata whakamutunga.
Mai i te tukanga whakarite i runga ake nei, ka kitea i roto i te tukanga oTe whakaputanga GFRP, ka taea te whakarite me te whakarite i te muka karāhe kia rite ki ngā kaupapa tukanga rerekē, ngā momo matihiko kapia rerekē mō ngā tono rerekē, me ngā tikanga tukatuka-muri rerekē ka taea te whakamahi hei whakatutuki i te whakaputanga o te GFRP mō ngā tono rerekē. I te nuinga o te wā, he maha ngā āhuatanga pai o te GFRP, e whakaahuahia ana i raro nei:
(1) Mama:He iti te taumaha motuhake o te GFRP ki te whakatauritea ki ngā rauemi whakarewa tuku iho, nō reira he mama noa iho. Nā tēnei ka whai hua i roto i ngā momo wāhanga maha, pērā i te rererangi, te motuka, me ngā taputapu hākinakina, ka taea te whakaiti i te taumaha mate o te hanganga, ka hua ake he pai ake te mahi me te whai huatanga o te wahie. Ina whakamahia ki ngā hanganga whare, ka taea e te āhua mama o te GFRP te whakaiti i te taumaha o ngā whare teitei.
(2) Kaha Teitei: Ngā rauemi kua whakapakarihia ki te muka karāheHe kaha nui, inā koa te kaha kume me te kaha piko. Mā te whakakotahitanga o te kapia whakakaha-muka me te muka karāhe ka taea te tu atu i ngā kawenga me ngā ahotea nui, nō reira he tino pai ngā āhuatanga ā-pūkaha o te rauemi.
(3) Ātete ki te waikura:He tino pai te ātete o te GFRP ki te waikura, ā, kāore e ngāwari ki ngā mea waikura pērā i te waikawa, te kawakore, me te wai tote. Nā tēnei ka waiho te rauemi hei painga nui mō ngā taiao uaua, pērā i te ao hangarau moana, ngā taputapu matū, me ngā tāke rokiroki.
(4) Ngā āhuatanga ārai pai:He pai ngā āhuatanga ārai o te GFRP, ā, ka taea te wehe i te kawe hiko hikohiko me te wera. Nā tēnei ka whakamahia whānuitia te rauemi i roto i te mara o te miihini hiko me te wehenga wera, pērā i te hanga papa ara iahiko, ngā ringaringa ārai, me ngā rauemi wehenga wera.
(5) Ātete wera pai:Kei a GFRPte ātete wera nuiā, ka taea te pupuri i te mahi pumau i roto i ngā taiao pāmahana teitei. Nā tēnei ka whakamahia whānuitia i roto i ngā mara rererangi, matū hinu, me te whakaputa hiko, pērā i te hanga i ngā mata miihini tāpoi hau, ngā wehewehenga oumu, me ngā wāhanga taputapu tipu hiko wera.
Hei whakarāpopototanga, he pai ngā painga o te GFRP, arā, he kaha teitei, he māmā, he ātete ki te waikura, he pai ngā āhuatanga ārai mate, me te ātete ki te wera. Nā ēnei āhuatanga ka whakamahia whānuitia i roto i ngā ahumahi hanga, rererangi, motuka, hiko, me te matū.
