Ko te taupoki poka tirotiro rauemi hiato he momo taupoki poka tirotiro, ā, e whakamāramahia ana ōna āhuatanga: ka whakakotahihia te taupoki poka tirotiro mā te whakamahi i te polymer hei rauemi matihiko, me te tāpiri i ngā rauemi whakapakari, ngā whakakī, me ētahi atu.
Ina hoki, ko te taupoki poka wai kapia (e kiia ana hoki ko te taupoki poka wai kirihou kua whakapakarihia ki te muka karāhe polymer/te taupoki poka wai rauemi hiato) he momo taupoki poka wai e whakamahi ana i te muka karāhe me ōna hua (te kakahu karāhe, te rīpene, te huruhuru hipi, te miro, me ētahi atu) hei rauemi whakapakari, me te kapia hangai hei rauemi matihiko. Kei roto ko te kapia polyester kore-mākū, ngā whakakī, ngā tīmatanga, ngā whakamātotoru, ngā tāpiringa iti te whakaiti, ngā kaihoko pokepoke kiriata, ngā tae me ngā rauemi whakapakari, ā, he momo hou o te hua taupoki poka e pokepokea ana i te pāmahana teitei.
I roto i ngā rauemi kua tāpirihia, ko ngā rauemi kua whakapakarihia ki te muka (te kakahu karāhe, te rīpene, te huruhuru hipi, te miro, me ētahi atu) ngā mea matua, e tohuhia ana e te iti o te taumaha motuhake, te nui o te kaha motuhake me te modulus motuhake. Hei tauira, ko te rauemi whakakotahi o te muka waro me te kapia epoxy, ko tōna kaha motuhake me te modulus motuhake he maha ngā wā nui ake i ērā o te maitai me te koranu konumohe, ā, he pai hoki te pumau matū, te ātete ki te waku me te kakahu, te ātete ki te hinu-ā-roto, te ātete ki te wera, te ātete ki te ngenge, te ātete ki te ngoki, te whakaiti haruru, te ārai hiko me ētahi atu āhuatanga. Ka taea e te whakakotahitanga o te muka graphite me te kapia te whiwhi i tētahi rauemi me te tauwehenga whānui tata ki te kore. Ko tētahi atu āhuatanga o ngā rauemi kua whakapakarihia ki te muka ko te anisotropy, nō reira ka taea te hoahoa i te whakaritenga o ngā muka kia rite ki ngā whakaritenga kaha o ngā wāhanga rerekē o te hua. Ko ngā whakakotahitanga konumohe matrix kua whakapakarihia ki ngā muka waro me ngā muka silicon carbide ka taea tonu te pupuri i te kaha me te modulus rawaka i te 500 °C.
Ka taea te wehewehe i ngā taupoki poka wai hiato ki te BMC me te SMC e ai ki te hiahia o te mākete, ngā tukanga whakaputa me ngā rauemi rerekē:
Ko ngā rauemi BMC (DMC) he matū hanga papatipu. E kiia ana ko te matū hanga papatipu polyester kāore i te mākū i Haina. Ko te rauemi mata matua he paraoa pokepoke rite ki te prepreg kua whakaranua katoatia ki te GF (muka karāhe tapatapahi), UP (kapia kāore i te mākū), MD (whakakī) me ngā momo tāpiri. I whakamahia tuatahitia ngā rauemi DMC i Tiamana ki te Hauāuru o mua me te United Kingdom i ngā tau 1960, kātahi ka whakawhanakehia i te United States me Hapani i ngā tau 1970 me 1980. Nā te mea he pai ngā āhuatanga hiko, ngā āhuatanga miihini, te ātete wera, te ātete waikura matū o te matū hanga BMC, ā, ka urutau ki ngā momo tukanga hanga, ka taea e ia te whakatutuki i ngā whakaritenga mahi o ngā momo hua, ā, he whānuitia te whakamahinga i roto i te hanga motuka, te kawe tereina, ngā taputapu hanga, ngā hua miihini me te hiko me ētahi atu mara.
He rauemi hanga pepa ngā rauemi hanga SMC. Ko ngā rauemi mata matua he mea hanga mai i te GF (miro motuhake), te UP (kapia kore-mākū), te tāpiringa iti-whakaiti, te MD (whakakī) me ngā momo āwhina. I puta tuatahi mai i Ūropi i te tīmatanga o te tekau tau atu i 1960, ā, i te tau 1965 pea, i whakawhanakehia e te Hononga o Amerika me Hapani tēnei mahi toi. I te mutunga o te tekau tau atu i 1980, i whakauruhia e tōku whenua ngā raina whakaputa SMC matatau me ngā tukanga whakaputa o tāwāhi. He tino pai ngā āhuatanga ārai hiko, ngā āhuatanga miihini, te pumau wera, me te ātete ki te waikura matū o ngā rauemi hanga SMC me ā rātou hua hanga SMC. Nō reira, he tino noa te whānuitanga o ngā tono o ngā hua SMC. Ko te ia whanaketanga o nāianei ko te whakakapi i ngā rauemi BMC ki ngā rauemi hanga SMC.
He mea nui te whakamahinga o ā mātou taupoki poka wai kapia i roto i ō mātou oranga, ā, ka kitea te hiranga o ngā taupoki poka wai kapia nā te mea ka taea e rātou te horoi i a rātou anō.
