Carbon fiber ine yakakwira chaiyo simba, yakakwira chaiyo modulus, kuneta kuramba, corrosion resistance uye zvimwe zvinhu zvakanakisa, zvinoshandiswa zvakanyanya muaerospace, indasitiri yemauto, midziyo yemitambo nemimwe minda. Carbon fiber yakasimbisa polymerization

Carbon fiber ine yakakwira chaiyo simba, yakakwira chaiyo modulus, kuneta kuramba, corrosion resistance uye zvimwe zvinhu zvakanakisa, zvinoshandiswa zvakanyanya muaerospace, indasitiri yemauto, midziyo yemitambo nemimwe minda. Iyo mechanic zvimiro zvekabhoni fiber yakasimbisa polymer matrix macomposites zvakanyanya zvinoenderana neiyo interface zvivakwa pakati pekabhoni fiber uye matrix. Nekudaro, iyo yakatsetseka pamusoro pekabhoni fiber, yakakwirira yemanzwiro zvimiro uye mashoma emakemikari anoshanda anoshanda mapoka anokonzeresa isina kusimba yekubatanidza pakati pekabhoni fiber uye matrix resin, uye iyo interface chikamu inowanzova isina kusimba chinongedzo chezvakaumbwa zvinhu. Iyo interfacial microstructure yekabhoni fiber composites ine hukama nehukama hwemukati. Iyo yepamusoro polarity yekabhoni fiber inopedzisira yarara mupamusoro morphology yekabhoni fiber uye marudzi emakemikari anoshanda mapoka. Zvose zviri zviviri kuwedzera kwemapoka anoshanda uye kuwedzera kwekukasharara kwekabhoni faibha pamusoro zvinokurudzira kuwedzera kwekabhoni fiber pamusoro pesimba. Nzvimbo dzepamusoro dzekabhoni fiber dzinonyanya kusanganisira pamusoro morphology, saizi yegroove uye kugovera, kushata kwepamusoro, simba remahara uye zvichingodaro. Mukutaura kwepamusoro morphology, kune akawanda pores, grooves, tsvina uye makristasi pamusoro pekabhoni fiber, iyo ine simba guru pahutano hwekubatanidza kwezvinhu zvinosanganiswa. Iko kemikari reactivity ye carbon fiber surface inonyatsoenderana nekusangana kwemapoka anoshanda, uye mapoka aya anoshanda anonyanya kushanda neokisijeni ine mapoka anoshanda akadai sechiedza cheboka, spindle boka uye epoxy boka. Huwandu hwemapoka anoshanda pamusoro pekabhoni faibha zvinoenderana nepamusoro electrochemical kurapwa nzira uye dhigirii kana tembiricha yefiber carbonization. Semuenzaniso, kurapwa kweasidhi kuchapa faibha dzakasiyana mashandiro mapoka pane alkali kurapwa, uye kune imwecheteyo kurapwa mamiriro, iyo yakakwirira tembiricha yecarbonization, mapoka mashoma anoshanda. Low modulus kabhoni faibha kazhinji ine mamwe mapoka anoshanda nekuda kwekuderera kwayo dhigirii recarbonization, saka ichaita neboka reepoxy mukugadzirira epoxy matrix macomposites, nepo kuita kweyakakwira modulus kabhoni fiber system inogona kufuratirwa, uye faibha neresin. kunyanya vane kudyidzana kusina simba. Zvidzidzo zvakawanda zvakaratidza kuti maumbirwo ezvimiro zvemakombisi anogona kuvandudzwa nekugadzirisa iyo interface microstructure yemakompositi nekugadziriswa kwepamusoro kwekabhoni fiber, inova imwe yenzvimbo dzekutsvagisa mumunda wekabhoni fiber cladding zvinhu.
