pūhanga whakamua
He pūnaha prepreg he whakahaere mōhio ki te hanga i ngā rau hua e mau ana i ngā rau kawe āhuarangi me ngā rehia matū. Kia whakatika, ka whaiwhai tēnei whare hanga i ngā take waehu, te whakahaere i te paetakanui, me ngā pūtake whakangungu rau i roto i te hanga i ngā prepregs pai ki te whakamahi i ngā whenua rerekē. Ko te mahi a te pūnaha kei te whakaputa i tētahi wā moemoeā e takoto ana i te whakawhanake i ngā kawe, ka mutu i te whakapuhuri i te kawe tuatahi. Kei roto i tēnei, ko ngā wā ōhanga whakamahana hei whakamahi i te pai rawa o te rehia, ko ngā rōpū whakahaere tūtonu hei whakamahi i te pai rawa o ngā kawe, me ngā whakahaere huringa pai hei whakaū i ngā āhuatanga pai o te rau. He momo āhua nui ngā take whakahaere e taea ana e ngā kaiwhakahaere te tirohia me te whakarerekē i ngā take nui, pērā i te waehu rehia, te tūtonu kawe, me te raupapa whakahaere. Ka noho ngā pūnaha prepreg tēnei i runga i ngā rōpū whakahaere pai e tirohia ana ngā take hanga, e whakamana ana i te pai rawa o te kawe i hangaia. E āhei ana ēnei pūnaha ki te whakahaere i ngā momo kawe rerekē, pērā i ngā kawe karboni, kāwaka, me ngā aramida, ahakoa ngā rehia rerekē hei whakamana i ngā take ā-tikanga. Ko te nui o ngā pūnaha prepreg ka whai oranga i te hanga i ngā rau hua i ngā whenua toa, pērā i te rorohiko, te motokā, te huringa hau, me ngā rau whakahaere tīmata.
