I te whanaketanga o te hangarau hanga rauemi hiato, me te hohonu haere o te māramatanga me te mōhiotanga ki ngā rauemi hiato i roto i te umanga kawe tereina, me te ahunga whakamua hangarau o te umanga hanga waka tereina, kua whānui haere te whānuitanga o te whakamahinga o ngā rauemi hiato i roto i ngā waka tereina. Kei te whakapai tonu hoki ngā momo, ngā taumata me ngā taumata hangarau o ngā rauemi hiato e whakamahia ana.
Ko ngā momo rauemi hiato kua whakamahia i roto i ngā waka tereina ko:
(1) Te kapia polyester kore-mākū pakari, me te āhua-mārō FRP;
(2) Kirihou whakakahangia ki te muka karāhe kapia phenolic;
(3) He kapia polyester kore-mākū FRP, he kaha teitei, ātete mura;
(4) He kirihou ātete mura te tāpiringa o te kapia polyester kore-mākū, he muka karāhe kua whakapakaritia, he iti ake te kaha;
(5) Rauemi muka waro.
Mai i ngā āhuatanga o te hua ko:
(1) Ngā wāhanga FRP e whakatakotoria ana e te ringa;
(2) Ngā wāhanga FRP kua whakarewaina;
(3) Ngā wāhanga FRP o te hanganga hanawiti;
(4) Ngā wāhanga muka waro.
Te Whakamahinga o te FRP i roto i ngā Waka Rerewē
1. Te whakamahinga tōmua o te FRP i roto i ngā waka tereina
I tīmata te whakamahinga o te FRP i roto i ngā waka tereina i te tekau tau atu i 1980, ā, i whakamahia tuatahitia i roto i ngā tereina hiko tere-iti 140km/h i hangaia i te motu. Ko te whānuitanga o te whakamahinga ko:
● te papa pakitara o roto;
● pereti o runga o roto;
● Wharepaku kirihou kua whakakahangia ki te muka karāhe kua huihuia;
Ko Katsukiyogi te kaupapa matua i whakamahia i taua wā. Ko te momo FRP i whakamahia ko te kapia polyester unsaturated FRP.
2. Te tono puranga o te FRP ki ngā waka tereina
I te tekau tau atu i 1990 ka whakamahia whānuitia te FRP ki ngā waka tereina, ā, ka āta pakari haere. E whakamahia ana mō te hanga waka tereina me ngā waka tereina o te tāone:
Te pakitara o roto o te rūma manuhiri;
●Pereti o runga o roto;
Wharepaku kirihou kua whakakahangia ki te muka karāhe kua huihuia;
Kaukau kirihou kua whakapakarihia ki te muka karāhe whakauru;
Rūma horoi kirihou whakakahangia ki te muka karāhe whakauru;
Paipa hauhautanga FRP, paipa putanga para;
● Nohoanga, anga nohoanga rānei.
I tēnei wā, kua neke te whāinga matua mai i te whakakapi i te rakau ki te whakapai ake i te kounga o ngā waka; ko ngā momo FRP e whakamahia ana ko te nuinga o te kapia polyester FRP kāore i te mākū.
3. I ngā tau tata nei, ko te whakamahinga o te FRP i roto i ngā waka tereina
Mai i te tīmatanga o tēnei rautau, kua whānuitia te whakamahinga o te FRP i roto i ngā waka tereina. Haunga te whakamahinga i roto i te hanga o ngā hua kua whakahuatia ake nei, he whānuitia hoki te whakamahinga i roto i te hanga o:
●Taupoki tuanui;
He paipa hau hou i runga i te tuanui;
●Ngā momo wāhanga rerekē me ngā āhua uaua o roto i te motuka, tae atu ki ngā panera pakitara o roto piko-ahu-toru me ngā panera tuanui taha; ngā panera uhi o ngā āhua motuhake; ngā panera pakitara kirihou honikoma kua whakapakaritia ki te muka karāhe; ngā wāhanga whakapaipai.
Ko te whāinga matua o te whakamahinga FRP i tēnei wā ko te hanga i ngā wāhanga me ngā whakaritenga mahi motuhake, ngā whakaritenga tauira uaua rānei. Hei tāpiri, kua pai ake te ātete ahi o te FRP i whakamahia i tēnei wā. Kua whānuitia te whakamahinga o te kapia polyester kore-kūkū FRP, he kapia ātete mura tauhohe me te tāpiri, ā, kua heke haere te whakamahinga o te kapia phenolic FRP.
4. Te whakamahinga o te FRP i roto i te EMU tere-teitei
Kua tino eke te whakamahinga o te FRP i roto i ngā EMU tereina tereina ki tētahi taumata pakari, nā te mea:
(1) E whakamahia ana te FRP i roto i te hanga i ngā wāhanga he mahi motuhake, he āhua me he hanganga uaua, ā, he mahi whānui tino pai ka taea te tu atu i ngā kawenga nui, pērā i ngā taha mua FRP kua whakatōngia, ngā kōwae tikanga whakatuwhera me te kati o mua, ngā hipoki tuanui aerodynamic, me ētahi atu.
(2) Kua whānuitia te whakamahinga o te kirihou whakakaha muka karāhe i whakarewaina (SMC)
Ko ngā painga o te whakamahinga o te kirihou whakakaha muka karāhe i whakarewaina hei hanga i ngā panera pakitara o roto o ngā pāhihi EMU tere-rahi i roto i ngā puranga e whai ake nei:
He teitei te tika o ngā āhuatanga o ngā wāhanga;
●Te kounga hanga me te taumata hua,
●Kua tutuki te mama;
●He pai mō te hanga hangarau papatipu.
(3) Whakapai ake i te taumata o te FRP e whakamahia ana i ētahi atu wāhanga
●Ka taea te hanga hei wāhanga me ngā kakano rerekē e hiahiatia ana;
He pai ake te kounga o te āhua, ā, he teitei ake te tika o te āhua me te rahi o ngā wāhanga;
●Ka taea te whakarite i te tae o te mata me te tauira i te wā kotahi.
I tēnei wā, ko te whakamahinga o te FRP kei roto ko te whakatutukitanga o ngā mahi me ngā āhua motuhake, me ngā whāinga taumata teitei ake pēnei i te amo i tētahi kawenga me te taumaha mama.
