Ko te whakamahinga o te pungarehu rere i roto i te turanga papa e aro nui ana ki ngā āhuatanga e rua: ngā rauemi pumau o te pungarehu rere (koime me te pungarehu rere) me ngā rauemi pumau o te pungarehu rere sima. Kua whakahiatohia ēnei rauemi e rua ki roto i ngā paerewa ā-motu, kua tino pakari te hangarau, ā, he maha ngā whakamahinga mahi. Ko te whakamahinga o te pungarehu rere ki runga i ngā mata papa ko te mata ranunga uku me te mata raima sima. E whakaatu ana te rangahau a Jiao Hua o Te Whare Wānanga o Chang'an i roto i tana tuhinga matua, ina whakakapia te pungarehu rere ki te paura konganuku katoa i roto i te ranunga uku AC-16, he ngoikore ake te ātete ki ngā pakaru pāmahana iti me te pumau pāmahana teitei ake i te mea i konatunatua ki te paura konganuku. , kua pai ake te pumau o te wai engari kāore i te tino kitea te pānga. I ako a Xie Jun, Wu Shaopeng, me ētahi atu i te pānga o te pungarehu rere maimoatanga mata me te kaihoko honohono ki te kino o te makuku o te ranunga uku. Ko te whakakotahi i te whakakī me te kaihoko honohono me te pungarehu rere ka kiia he whakarerekētanga pungarehu rere hiato. Ko ngā āhuatanga o te whakarerekētanga pungarehu rere hiato i tautuhia nuitia e te karu hiko matawai me te tirohanga infrared Fourier. Hei whakakī, i aromatawaihia tōna pānga ki te aro o te makuku o ngā ranunga uku mā roto i ngā whakamātautau modulus tensile strength, te ngoki pūmau, me ngā whakamātautau ngenge tensile . E whakaatu ana ngā hua he nui te kaha tensile me te ōwehenga kaha tensile o te ranunga uku me te whakarerekētanga pungarehu rere hiato i te wā hukapapa, ā, he tino aro ki te makuku. Hei tāpiri, i whakaatu te ranunga uku whakarerekētanga pungarehu rere hiato i te modulus tensile pai ake, te ātete ki te whakarerekētanga tuturu, me te roa o te ngenge i muri i te maimoatanga kino makuku motuhake. Whakatau: Ka taea e te whakarerekētanga pungarehu rere hiato te whakapai ake i te aro o te makuku o te ranunga uku.
He whānuitia hoki te whakamahinga o ngā pareparenga pungarehu rere i roto i te hangarau rori, inā koa i ngā wāhanga rori turanga oneone ngohengohe. Ka taea te whakamahi katoa i te taumaha māmā o te pungarehu rere hei whakaiti i te taumaha o te pareparenga me te taumahatanga tāpiri o te turanga oneone ngohengohe, ā, ka whakaitihia te taunga katoa me te whakapai ake i te pumau o te pareparenga. Waihoki, mā te whakakī i te pungarehu rere ki te oneone whakakī-teitei i te pito o te piriti ka taea te whakapai ake i te raruraru peke o te pito o te piriti i puta mai i te taunga i puta mai i te taumaha-ake o te oneone whakakī-teitei i te pito o te piriti. I ako a Liu Tiejun i ngā āhuatanga miihini o te pungarehu rere i whakamahia hei whakakī pareparenga, ā, i tae mai ki ngā whakatau e whai ake nei: ko te matotoru maroke o te pungarehu rere i whakaatu i te ia o te pikinga tuatahi, kātahi ka heke iho me te pikinga o te ihirangi makuku, ā, ko te matotoru maroke mōrahi o te ihirangi makuku he 19%; Ka heke haere te tauwehenga uruhanga o te pungarehu waro me te pikinga o te matotoru maroke. Ina iti iho te matotoru maroke o te pungarehu rere i te 1.35g/cm3, tata kore he pānga o te matotoru maroke ki tōna tauwehenga uruhanga; Ka piki ake te piripono o te pungarehu rere me te nui o te wai. Ina piki ake, ina heke iho hoki te nui o te makuku o te pungarehu rere, ā, he puhoi te hekenga ina iti iho te nui o te makuku i te 26%, ki te kore ka tere ake te heke; ina piki ake te nui o te makuku o te pungarehu rere mā te 1%, ka heke te koki waku ā-roto mā te 0.25° pea; Ka piki haere te piripono o te pungarehu waro i te pikinga o te tohu whakakīkī, ko te koki waku ā-roto o te pungarehu rere ka piki haere i te pikinga o te tohu whakakīkī; ko te nui o te makuku o te pungarehu rere ka tata atu ki te nui o te makuku tino pai, ka tata atu rānei ki te 100% te whakakīkī, ka iti ake te hekenga o te piripono me te koki waku ā-roto me te pikinga o ngā wā wiri, ā, ka māmā ake te tae ki te āhua pumau i te wā tōmua o te wiri. I whakahaerehia hoki e Chen Yunyong rāua ko Gao Liang ngā whakamātautau tauira ā-roto i runga i ngā pareparenga pungarehu rere whakakaha. E ai ki te mātāpono o te ōritetanga, i whakaitihia e ngā tāne tokorua te pareparenga tuturu i te ōwehenga 1:8, ā, i whakamahia te matawhenua ā-rua hei rauemi whakakaha, ā, i whakahaerehia he rangahau whakamātautau mō te ahotea me te taumahatanga o te pareparenga kua whakakahangia e te pungarehu rere. E whakaatu ana ngā hua ka taea te whakaiti i te taunga kore taurite o te pareparenga pungarehu rere mā te whakakaha i te geogrid, ā, ka taea hoki te whakapai ake i te kaha o te pareparenga.
