Te tukanga whakarite o ngā rauemi hiato muka waro

He Tirohanga Whānui mō ngā Rauemi Whakakotahi Waro-Waro

Rauemi hiato waro/waro (C/C)He rauemi hiato kua whakapakarihia ki te muka waro, he maha ngā āhuatanga pai rawa atu pēnei i te kaha me te modulus teitei, te taumaha motuhake māmā, te tauwehenga whānui wera iti, te ātete ki te waikura, te ātete ki te ru wera, te ātete ki te waku pai, me te pumau matū pai. He momo hou tēnei o te rauemi hiato pāmahana tino teitei.

Rauemi hiato C/CHe rauemi hangarau whakauru hanganga-mahi wera tino pai. Pērā i ētahi atu rauemi hiato mahi-teitei, he hanganga hiato i hangaia mai i te wāhanga whakakaha-muka me te wāhanga taketake. Ko te rerekētanga ko te wāhanga whakakaha me te wāhanga taketake he mea hanga mai i te waro parakore me ngā āhuatanga motuhake.

Ngā rauemi hiato waro/warohe mea hanga te nuinga ki te huruhuru waro, te kakahu waro, te muka waro hei whakakaha, me te waro i whakapūtāhia ki te kohu hei anga, engari kotahi anake te huānga, ko te waro. Hei whakanui ake i te mātotoru, ka whakakiia te waro i puta mai i te whakapūtātanga ki te waro, ka whakakiia rānei ki te kapia (ki te uku rānei), arā, e toru ngā rauemi waro e hangaia ai te waro/waro.

Te tukanga hanga rauemi hiato waro-waro

1) Kōwhiringa o te muka waro

Ko te kōwhiringa o ngā paihere muka waro me te hoahoa hanganga o ngā papanga muka te pūtake mō te hanga.C/C hiatoKa taea te whakatau i ngā āhuatanga ā-pūkaha me ngā āhuatanga ā-mahana o ngā hiato C/C mā te whiriwhiri whakaaro nui i ngā momo muka me ngā tawhā raranga papanga, pērā i te whakatakotoranga o te paihere miro, te mokowā o te paihere miro, te nui o te paihere miro, me ētahi atu.

2) Te whakarite i te muka waro

Ko te muka waro he mea hanga ki te āhua hanganga e hiahiatia ana o te muka kia rite ki te āhua hua me ngā whakaritenga mahi hei whakahaere i te tukanga whakakīkī. E toru ngā tikanga tukatuka matua mō ngā wāhanga hanganga kua hangaia: te raranga ngohengohe, te raranga mārō me te raranga whakaranu ngohengohe me te mārō. Ko ngā tukanga raranga matua ko: te raranga miro maroke, te whakaritenga rōpū tokotoko kua whakakīia ki mua, te whatu raranga pai, te takai muka me te raranga whānui maha-ahu-toru. I tēnei wā, ko te tukanga raranga matua e whakamahia ana i roto i ngā rauemi hiato C ko te raranga whānui maha-ahu-toru. I roto i te tukanga raranga, ka whakaritea ngā muka raranga katoa ki tētahi ahunga. Ka wehea ia muka ki tētahi koki i tōna ake ahunga, ka rarangahia tetahi ki tetahi hei hanga papanga. Ko tōna āhuatanga he taea te hanga i tētahi papanga whānui maha-ahu-toru, ka taea te whakahaere pai i te nui o ngā muka i ia ahunga o te rauemi hiato C/C, kia taea ai e te rauemi hiato C/C te whakaatu i ngā āhuatanga miihini whaitake i ngā ahunga katoa.

3) Te tukanga whakakīkī C/C

Ko te nui me te whai huatanga o te whakakīkī ka pāngia e te hanganga o te papanga me ngā tawhā tukanga o te rauemi turanga. Ko ngā tikanga tukanga e whakamahia ana i tēnei wā ko te whakapūpū waro, te whakatakoto kohu matū (CVD), te whakaurunga kohu matū (CVI), te whakatakoto wai matū, te whakakorikori me ētahi atu tikanga. E rua ngā momo matua o ngā tikanga tukanga: te tukanga whakapūpū waro me te tukanga whakaurunga kohu matū.

Te whakakī-te whakapūkara o te wāhanga wai

He tino māmā te tikanga whakakī wai i roto i ngā taputapu, ā, he whānui te whakamahinga, nō reira he tikanga nui te tikanga whakakī wai mō te whakarite rauemi hiato C/C. Ko te tuku i te preform i hangaia ki te muka waro ki roto i te impregnant wai, kia uru katoa ai te impregnant ki roto i ngā āputa o te preform mā te pēhanga, kātahi ka puta mā roto i tētahi raupapa tukanga pēnei i te whakamaroke, te whakapūngao waro, me te whakakāwhata, kia puta ai.Ngā rauemi hiato C/CKo tōna ngoikoretanga he mea nui te whakakī me te whakapūnga waro kia tutuki ai ngā whakaritenga kiato. He mea tino nui te hanganga me te hanganga o te whakapūnga i roto i te tikanga whakapūnga āhua wai. Ehara i te mea ka pā ki te whai huatanga whakapūnga anake, engari ka pā hoki ki ngā āhuatanga ā-pūkaha me ā-tinana o te hua. Ko te whakapai ake i te hua whakapūnga waro o te whakapūnga me te whakaiti i te matotoru o te whakapūnga tētahi o ngā take matua hei whakatau i roto i te whakarite rauemi hiato C/C mā te tikanga whakapūnga āhua wai. Ko te matotoru teitei me te hua whakapūnga waro iti o te whakapūnga tētahi o ngā take nui mō te utu nui o ngā rauemi hiato C/C. Mā te whakapai ake i te mahi a te whakapūnga e kore e taea anake te whakapai ake i te whai huatanga whakaputa o ngā rauemi hiato C/C me te whakaiti i ō rātou utu, engari ka whakapai ake hoki i ngā āhuatanga rerekē o ngā rauemi hiato C/C. Te maimoatanga ārai-waikura o ngā rauemi hiato C/C Ka tīmata te waikura o te muka waro i te 360°C i te rangi. He pai ake te muka graphite i te muka waro, ā, ka tīmata te waikura o tōna pāmahana waikura i te 420°C. Ko te pāmahana waikura o ngā rauemi hiato C/C e tata ana ki te 450°C. He tino ngāwari te waikura o ngā rauemi hiato C/C i roto i te hau waikura pāmahana teitei, ā, ka tere te piki o te tere waikura i te pikinga o te pāmahana. Ki te kore he tikanga ārai-waikura, ko te whakamahinga roa o ngā rauemi hiato C/C i roto i te taiao waikura pāmahana teitei ka puta he hua kino. Nō reira, kua noho te maimoatanga ārai-waikura o ngā rauemi hiato C/C hei wāhanga nui o tana tukanga whakarite. Mai i te tirohanga a te hangarau ārai-waikura, ka taea te wehewehe ki te hangarau ārai-waikura ā-roto me te hangarau paninga ārai-waikura.

Wāhanga Kohu Matū

Ko te whakatakoto matū kohu (CVD, CVI rānei) he whakatakoto tika i te waro ki roto i ngā pūwero o te parapara hei whakatutuki i te kaupapa o te whakakī i ngā pūwero me te whakanui ake i te kiato. He ngāwari te whakakāwhata i te waro kua whakatakotoria, ā, he pai te hototahi ā-tinana ki te muka. Kāore e mimiti i te wā e whakakāwhata anōtia ana pērā i te tikanga whakakī, ā, he pai ake ngā āhuatanga ā-tinana me ā-pūkaha o tēnei tikanga. Heoi, i te wā o te tukanga CVD, ki te whakatakotoria te waro ki runga i te mata o te parapara, ka ārai i te hau kei horapa ki roto i ngā pūwero o roto. Me tango ā-mīhini te waro kua whakatakotoria ki runga i te mata, kātahi ka whakahaere i tētahi atu whakatakoto. Mō ngā hua matotoru, he uaua anō hoki te tikanga CVD, ā, he tino roa hoki te huringa o tēnei tikanga.
