pukapuka hirama multiaxial
Ko te īhirihi mātātoko karboni he whanaketanga hou mō te hangarau matēria kōpae, e mōhiotia ana mā tōna tohu takotoranga āhuahua ki ngā tātaitanga rerekē. Ko tēnei matēria matatau he tauwāhi o ngā aho kihini karboni unidirectional, ka tūhonoatia tika ki ngā kona rerekē hei waihanga i tētahi hanganga kaha me te māmā. Arā noa i te tikanga ake o ngā aho pīra, ko te īhirihi mātātoko karboni e whakamahia ana i ngā aho tino torona, e kore nei e pakaru, e whakapakari ai i te kaha me ngā āhuatanga mahi. Ko te hanganga maro o te matēria e whai wāhi ana i ngā takotoranga 0, 45, 90, me -45 kīato, e whakaae ai ki te wehe tika i te tāpoi ki runga i ngā aronga maha. Mā tēnei hanganga hangai ka hua mai ngā āhuatanga mekameka ōrite, tae atu ki te kaha tōpuarenga kua whakapakari, te whakapai ake i te kaha ki te patuki, me te mahi taumaha tino pai. Ka kitea te matēria i ngā rohe rerehua hāpai, mai i te ao hāpori me te motuka ki ngā taonga hākinakina me te hiko wera-wera. Ko tana kaha ki te whirihora mā te tohu aho me te rahi o te maro ka nui te uara mō ngā whakamahinga e hiahiatia ana ngā āhuatanga kaha āhuatanga. Ko te huringa hanga e whai ana i te hangarau tuhinga matatau e pupuri ana i te tūranga aho i te wā e hono ana i ngā maro, e tiaki ana i te kaha hanga engari kāore e kino ki ngā āhuatanga taketake o te matēria. Ko tēnei ara hou ki te tūhono aho ka hua mai te whai wāhi pai ake me ngā āhuatanga mekameka tino pai ake i ngā matēria tikanga.
