Ko ngā muka te mea nui rawa atu mō ngā āhuatanga ā-tinana o ngā mea hanga tahi. Ko te tikanga, ina honoa ngā kapia me ngā muka, he tino ōrite ō rāua āhuatanga ki ērā o ngā muka takitahi. E whakaatu ana ngā raraunga whakamātautau ko ngā rauemi whakakaha-muka ngā wāhanga e pikau ana i te nuinga o te kawenga. Nō reira, he mea nui te whiriwhiri papanga i te wā e hoahoa ana i ngā hanganga hanga tahi.
Tīmatahia te tukanga mā te whakatau i te momo whakapakari e hiahiatia ana mō tō kaupapa. Ka taea e te kaihanga noa te whiriwhiri i waenga i ngā momo whakapakari e toru: te muka karāhe, te muka waro me te Kevlar® (muka aramid). Ko te muka karāhe te mea tino pai, ko te muka waro ia he pakari teitei, he ātete ki te pakū o te Kevlar®. Kia maumahara ka taea te whakakotahi i ngā momo papanga ki roto i ngā paparanga ranu hei hanga i ngā puranga ranu e tuku ana i ngā painga o ngā rauemi maha atu i te kotahi.
Ngā Whakapakari Karāhe
He rauemi mōhio te muka karāhe. Ko te muka karāhe te tūāpapa o te umanga hiato. Kua whakamahia i roto i ngā tono hiato maha mai i te tekau tau atu i 1950, ā, e mārama ana ōna āhuatanga ā-tinana. He mama te muka karāhe, he kaha kume me te kaha pēhi, ka taea te tu atu i te kino me te kawenga huringa, ā, he ngāwari ki te whakahaere. Ko ngā hua e puta mai ana i te hanga e mōhiotia ana ko ngā hua kirihou whakapakari muka karāhe (FRP). He mea noa i roto i ngā wāhanga katoa o te oranga. Ko te take i kiia ai ko te muka karāhe nā te mea ka hangaia tēnei momo miro muka mā te whakarewa i te kuata me ētahi atu rauemi konganuku i ngā pāmahana teitei ki roto i te paru karāhe. Kātahi ka unuhia i ngā miro tere teitei. Nā te hanganga o tēnei momo muka he maha ngā mea rerekē. Ko ngā painga ko te ātete wera, te ātete waikura, te kaha ake. He pai te whakamarumaru. Ā, ko te ngoikoretanga o te muka waro he pakarukaru ake te hua. He ngoikore te ngāwari. Kāore e ātete kakahu. I tēnei wā, he ngāwari te whakamarumaru, te tiaki wera, te ārai waikura me te maha atu o ngā mara e whakamahi ana i te kirihou whakapakari muka karāhe.
Ko te muka karāhe te mea e whakamahia whānuitia ana o ngā mea hanga katoa e wātea ana. Ko te nuinga o tēnei nā tōna utu iti me ōna āhuatanga ā-tinana. He pai te muka karāhe mō ngā kaupapa o ia rā me ngā wāhanga kāore e hiahiatia he papanga muka uaua rawa hei whakanui ake i te kaha me te roa.
Hei whakanui ake i te kaha o te muka karāhe, ka taea te whakamahi me ngā kapia epoxy, ā, ka taea te whakamaroke mā te whakamahi i ngā tikanga whakapiri paerewa. He tino pai mō ngā mahi i roto i ngā ahumahi motuka, moana, hanga, matū me te rererangi, ā, he mea noa te whakamahi i roto i ngā taonga hākinakina.

Whakakaha muka Aramid
He matū hangarau teitei te muka aramid. He kaha teitei, he ātete ki te pāmahana teitei, he ātete ki te waikura, he mama me ētahi atu āhuatanga, ā, ko tētahi o ngā rauemi matua o te umanga parepare. He maha ngā whakamahinga i roto i ngā taputapu ātete matā, ngā taputapu rere.
Ko ngā muka aramid tētahi o ngā muka hangai kaha-teitei tuatahi kia whakaaetia i roto i te umanga kirihou whakakaha-muka (FRP). He mama ngā muka para-aramid karaehe hiato, he tino kaha te kume, ā, e kiia ana he tino ātete ki te pānga me te pakū. Ko ngā tono noa ko ngā anga mama pērā i ngā waka hoe me ngā waka, ngā panera tinana rererangi me ngā oko pēhanga, ngā karapu ātete-tapa, ngā koti ārai-matā me te maha atu. Ka whakamahia ngā muka aramid me ngā kapia epoxy, vinyl ester rānei.

Whakakaha muka waro
Neke atu i te 90% te nui o te waro i roto i te umanga FRP, ā, ko te muka waro te mea tino kaha ki te kume. Inaa hoki, koia te mea tino kaha ki te pēhi me te piko o te umanga. I muri i te tukatuka, ka whakakotahihia ēnei muka hei hanga i ngā whakakaha muka waro pērā i ngā papanga me ngā tō. Ka whakaratohia e te whakakaha muka waro he kaha motuhake me te pakari motuhake, ā, he nui ake te utu i ētahi atu whakakaha muka.
Hei whakanui ake i te kaha o te muka waro, me whakamahi tahi me ngā kapia epoxy, ā, ka taea te whakamaroke mā te whakamahi i ngā tikanga whakapiri paerewa. He pai mō ngā mahi motuka, moana me te rererangi, ā, he maha ngā wā ka whakamahia i roto i ngā taonga hākinakina.
