I-Carbon FiberIsitsha Sokucindezela Esihlanganisiwe Esigoqekayo siyisitsha esinodonga oluncane esakhiwe nge-liner evalwe kahle kanye nesendlalelo se-fiber-wound esinamandla aphezulu, esakhiwa kakhulu ngenqubo yokugoqa nokweluka i-fiber. Uma kuqhathaniswa nemikhumbi yensimbi yendabuko, i-liner yemikhumbi yengcindezi ehlanganisiwe isebenza njengendawo yokugcina, ukuvala kanye nokuvikela ukugqwala kwamakhemikhali, kanti ungqimba oluhlanganisiwe lusetshenziswa kakhulu ukuthwala umthwalo wengcindezi yangaphakathi. Ngenxa yamandla aphezulu athile kanye nokwakheka okuhle kwezingxenye ezihlanganisiwe, imikhumbi yengcindezi ehlanganisiwe ayithuthukisanga nje kuphela umthamo wayo wokuthwala umthwalo, kodwa futhi inciphise kakhulu isisindo semikhumbi uma kuqhathaniswa nemikhumbi yensimbi yendabuko.
Ingqimba yangaphakathi yesitsha sokucindezela i-fiber-wound ikakhulukazi isakhiwo se-liner, umsebenzi waso oyinhloko ukusebenza njengesivikelo sokuvala ukuvimbela ukuvuza kwamagesi anomfutho ophezulu noma uketshezi olugcinwe ngaphakathi, futhi ngesikhathi esifanayo ukuvikela ungqimba lwangaphandle lwe-fiber-wound. Lolu ngqimba ngeke lugugulwe yizinto ezigcinwe ngaphakathi futhi ungqimba lwangaphandle luyingqimba ye-fiber-wound eqiniswe nge-resin matrix, esetshenziswa kakhulu ukumelana nemithwalo eminingi yokucindezela esitsheni sokucindezela.
1. Isakhiwo semithambo yokucindezela yenxeba le-fiber
Kunezinhlobo ezine eziyinhloko zesakhiwo semikhumbi yokucindezela ehlanganisiwe: i-cylindrical, i-spherical, i-annular kanye ne-rectangular. Isitsha esiyisilinda sakhiwe ngesigaba sesilinda kanye namakhanda amabili. Imikhumbi yokucindezela yensimbi yenziwa yaba yizimo ezilula ezinamandla amaningi agciniwe ohlangothini lwe-axial. Imikhumbi eyindilinga inokucindezeleka okulinganayo eziqondisweni ze-warp kanye ne-weft ngaphansi kwengcindezi yangaphakathi futhi iyisigamu sokucindezeleka okujikelezayo kwemikhumbi eyindilinga. Amandla ezinto zensimbi alingana kuzo zonke izinkomba, ngakho-ke isitsha esiyindilinga esenziwe ngensimbi senzelwe amandla alinganayo, futhi sinobunzima obuncane lapho ivolumu kanye nengcindezi kuqinisekile. Isimo samandla esitsheni esiyindilinga siyindlela engcono kakhulu, udonga lwesitsha lungenziwa lube luncane kakhulu. Kodwa-ke, ngenxa yobunzima obukhulu ekukhiqizeni izitsha eziyindilinga, ngokuvamile ezisetshenziswa kuphela emkhathini nakwezinye izikhathi ezikhethekile. Isitsha sendandatho ekukhiqizweni kwezimboni asivamile kakhulu, kodwa kwezinye izikhathi ezithile noma sidinga lesi sakhiwo, isibonelo, izimoto zasemkhathini ukuze zisebenzise ngokugcwele isikhala esilinganiselwe, zizosebenzisa lesi sakhiwo esikhethekile. Isitsha esingunxande sihloselwe ikakhulukazi ukuhlangabezana lapho isikhala silinganiselwe, sisebenzise isikhala kakhulu kanye nokusetshenziswa kwezakhiwo, njengezimoto zamathangi angunxande, izimoto zamathangi esitimela, njll., izitsha ezinjalo ngokuvamile ziyizitsha ezinomfutho ophansi noma izitsha zomfutho womoya futhi izidingo zekhwalithi yokukhanya zingcono.
Ubunzima besakhiwo se-inhlanganiselaisitsha sokucindezela uqobo, ushintsho oluzumayo lobukhulu bekhanda nekhanda, ubukhulu obuguquguqukayo kanye ne-engeli yekhanda, njll., kuletha ubunzima obukhulu ekwakhiweni, ekuhlaziyweni, ekubalweni nasekubunjweni. Ngezinye izikhathi, imikhumbi yokucindezela ehlanganisiwe ayidingi nje kuphela ukugoqwa ngama-engeli ahlukene kanye nezilinganiso zesivinini eziguquguqukayo engxenyeni yekhanda, kodwa futhi idinga ukusebenzisa izindlela ezahlukene zokugoqa ngokwezakhiwo ezahlukene. Ngesikhathi esifanayo, ithonya lezici ezisebenzayo njenge-friction coefficient kumele licatshangelwe. Ngakho-ke, ukwakheka kwesakhiwo okulungile nokunengqondo kuphela okungaqondisa ngokufanele inqubo yokukhiqiza ukugoqa kwemikhumbi yokucindezela ehlanganisiwe, ukuze kukhiqizwe imikhiqizo yemikhumbi yokucindezela ehlanganisiwe elula ehlangabezana nezidingo zomklamo.
2. Izinto zomthambo wokucindezela we-fiber-wound
Njengengxenye eyinhloko ethwala umthwalo, ungqimba lokugoqa ifayibha kumele lube namandla aphezulu, i-modulus ephezulu, ukuminyana okuphansi, ukuzinza kokushisa kanye nokumanzi okuhle kwe-resin, kanye nokucutshungulwa okuhle kokugoqa kanye nokuqina okufanayo kwefayibha. Imicu yokuqinisa evame ukusetshenziswa emikhunjini yokucindezela elula ehlanganisiwe ifaka phakathiimicu yekhabhoni, imicu ye-PBO,imicu ye-polyamine enuka kamnandi, kanye nemicu ye-UHMWPE.
