-Ubuchule obumangalisayo beePolymers zeCarbon Fiber eQiniswayo.
I-Carbon FiberIiComposites zePolymer ezongeziweyo (CFRP) zikhaphukhaphu, izixhobo ezomeleleyo ezisetyenziswa ekwenzeni iimveliso ezininzi ezisetyenziswa kubomi bethu bemihla ngemihla. Ligama elisetyenziselwa ukuchaza i-fiber-reinforcedimathiriyeli edibeneyoesebenzisa i-carbon fiber njengeyona nxalenye yesakhiwo. Kufuneka kuqatshelwe ukuba "P" kwiCFRP inokumela "iplastiki" endaweni ye "polymer."
Ngokubanzi, iicomposites zeCFRP zisebenzisa i-thermosetting resins njenge-epoxy,i-polyester, okanye i-vinyl ester. Nangonaiintlazi ze-thermoplasticzisetyenziswa kwiiComposites zeCFRP, "iCarbon Fiber Reinforced Thermoplastic Composites" zihlala zihamba nge-acronym yazo, i-CFRTP composites.
Xa usebenza kunye ne-composites okanye ngaphakathi kwishishini le-composites, kubalulekile ukuqonda imigaqo kunye nezifinyezo. Okubaluleke ngakumbi, kuyimfuneko ukuyiqondaiipropathi zeFRP compositekunye nobuchule bezinto ezahlukeneyo zokuqinisa ezifana ne-carbon fiber.
Iipropati zeCFRP Composites
Izinto ezidityanisiweyo, zomelezwe nge-carbon fiber, zahlukile kunezinye ii-FRP composite zisebenzisa izinto zemveli ezifana ne-fiberglass okanyei-aramid fiber. Iipropathi zeCFRP ezidibanisayo eziluncedo ziquka:
Ubunzima obuKhala:A ngokwemvelii-fiberglass eyomeleziweyo ehlanganisiweyousebenzisa i-fiber yeglasi eqhubekayo ene-fiber ye-70% yeglasi (ubunzima beglasi / ubunzima bubonke), iya kuba noxinano lwe-.065 pounds per cubic intshi.
Ngeli xesha, iComposite yeCFRP, enobunzima obufanayo obungama-70% wefayibha, isenokuba noxinano lwe-.055 yeeponti nge-intshi nganye.
Amandla Ongeziweyo:Ayiphelelanga nje ekubeni i-carbon fiber composites ilula, kodwa imidibaniso yeCFRP yomelele kwaye iqinile ngeyunithi nganye yobunzima. Oku kuyinyani xa uthelekisa i-carbon fiber composites kwifiber yeglasi, kodwa nangakumbi xa kuthelekiswa nesinyithi.
Ngokomzekelo, umgaqo ohloniphekileyo wesithupha xa uthelekisa intsimbi kunye ne-CFRP composites kukuba isakhiwo se-carbon fiber samandla alinganayo siya kuba nobunzima be-1/5 yentsimbi. Unokucinga ukuba kutheni iinkampani zeemoto ziphanda ngokusebenzisa i-carbon fiber endaweni yentsimbi.
Xa kuthelekiswa imidibaniso ye-CFRP kunye ne-aluminiyam, enye yezona zintsimbi zikhaphukhaphu zisetyenzisiweyo, uqikelelo olusemgangathweni kukuba ulwakhiwo lwe-aluminiyam olunamandla alinganayo lunokuba nobunzima obuphindwe ka-1.5 bobume bekhabhon fiber.
Kakade ke, zininzi izinto eziguquguqukayo ezinokutshintsha olu thelekiso. Ibakala kunye nomgangatho wezinto eziphathekayo zinokwahluka, kunye ne-composites, iinkqubo yokuvelisa, i-fiber architecture, kunye nomgangatho kufuneka kuthathelwe ingqalelo.
Izinto ezingeloncedo kwiiComposites zeCFRP
Ixabiso:Nangona izinto ezimangalisayo, kukho isizathu sokuba i-carbon fiber ingasetyenziswa kwisicelo ngasinye. Okwangoku, imidibaniso yeCFRP ixabisa kakhulu kwiimeko ezininzi. Ngokuxhomekeke kwiimeko zemarike zangoku (ubonelelo kunye nemfuno), uhlobo lwe-carbon fiber (i-aerospace vs. ibakala lokuthengisa), kunye nobukhulu be-fiber tow, ixabiso le-carbon fiber lingahluka kakhulu.
I-carbon fiber eluhlaza kwisiseko sexabiso-ngeponti nganye ingaba naphi na phakathi kwamaxesha ama-5 ukuya kuma-25-amaxesha abiza kakhulu kune-fiberglass. Lo mahluko mkhulu ngakumbi xa uthelekisa intsimbi kunye nemixube yeCFRP.
Ukuqhuba:Oku kunokuba luncedo kwiicomposites ze-carbon fiber, okanye ukungonakali kuxhomekeke kwisicelo. Ifayibha yeCarbon iqhuba kakhulu, ngelixa ifayibha yeglasi ikhusela. Abaninziizicelo zisebenzisa i-fiber yeglasi, kwaye ayikwazi ukusebenzisa i-carbon fiber okanye isinyithi, ngokungqongqo ngenxa ye-conductivity.
Ngokomzekelo, kwishishini eliluncedo, iimveliso ezininzi ziyafuneka ukuba zisebenzise imicu yeglasi. Ikwasesinye sezizathu zokuba iileli zisebenzise ifayibha yeglasi njengomzila weleli. Ukuba i-fiberglass ileli yayiza kudibana nentambo yamandla, amathuba okuba i-electrocution iphantsi kakhulu. Oku akuyi kuba njalo ngeleli yeCFRP.
Nangona iindleko ze-CFRP composites zisephezulu, ukuqhubela phambili kobuchwepheshe obutsha ekuveliseni kuyaqhubeka ukuvumela iimveliso ezingabizi kakhulu. Ngethemba, ebomini bethu, siya kukwazi ukubona i-carbon fiber enexabiso eliphantsi elisetyenziswe kuluhlu olubanzi lwabathengi, i-industrial, kunye ne-automotive applications.
