- Amandla Amangalisayo weCarbon Fiber Reinforced Polymers.
I-Carbon FiberI-Reinforced Polymer Composites (CFRP) yizinto ezingasindi, eziqinile ezisetshenziswa ekwenzeni imikhiqizo eminingi esetshenziswa ekuphileni kwethu kwansuku zonke. Yigama elisetshenziselwa ukuchaza i-fiber-reinforcedimpahla eyinhlanganiselaesebenzisa i-carbon fibre njengengxenye yesakhiwo esiyinhloko. Kufanele kuqashelwe ukuthi u-“P” ku-CFRP ungaphinda umele “ipulasitiki” esikhundleni sokuthi “ipolymer.”
Ngokuvamile, izinhlanganisela ze-CFRP zisebenzisa izinhlaka ze-thermosetting njenge-epoxy,i-polyester, noma i-vinyl ester. Nakubaama-resin thermoplasticasetshenziswa kuma-CFRP Composites, “I-Carbon Fiber Reinforced Thermoplastic Composites” ivamise ukuhamba ngesifinyezo sazo, izinhlanganisela ze-CFRTP.
Lapho usebenza ngezinhlanganisela noma ngaphakathi kwemboni yezinhlanganisela, kubalulekile ukuqonda imigomo nama-akhronimi. Okubaluleke nakakhulu, kuyadingeka ukuqondaizakhiwo zezinhlanganisela ze-FRPkanye namakhono okuqiniswa okuhlukahlukene njenge-carbon fiber.
Izakhiwo ze-CFRP Composites
Izinto ezihlanganisiwe, eziqiniswe nge-carbon fiber, zihlukile kunezinye izinhlanganisela ze-FRP zisebenzisa izinto zendabuko ezifana ne-fiberglass nomai-aramid fiber. Izakhiwo ze-CFRP Composites ezinenzuzo zihlanganisa:
Isisindo Esilula:Owendabukoi-fiberglass eyinhlanganisela eqinisiweusebenzisa i-fiber yengilazi eqhubekayo ene-fiber engu-70% yengilazi (isisindo sengilazi / isisindo esiphelele), ngokuvamile izoba nokuminyana okungu-.065 pounds per cubic inch.
Ngaleso sikhathi, inhlanganisela ye-CFRP, enesisindo esifanayo esingu-70% sefayibha, ngokuvamile ingase ibe nokuminyana okungu-.055 pounds per cubic inch.
Amandla Angeziwe:Akukhona nje kuphela ukuthi izinhlanganisela ze-carbon fibre isisindo esilula, kodwa izinhlanganisela ze-CFRP zinamandla kakhulu futhi ziqinile ngeyunithi ngayinye yesisindo. Lokhu kuyiqiniso uma kuqhathaniswa izinhlanganisela ze-carbon fibre ne-glass fiber, kodwa nakakhulu uma kuqhathaniswa nezinsimbi.
Isibonelo, umthetho ohloniphekile wesithupha uma uqhathanisa insimbi nezinhlanganisela ze-CFRP ukuthi isakhiwo se-carbon fibre enamandla alinganayo ngokuvamile sizoba nesisindo esingu-1/5 sensimbi. Ungacabanga ukuthi kungani izinkampani zezimoto ziphenya zisebenzisa i-carbon fiber esikhundleni sensimbi.
Lapho uqhathanisa izinhlanganisela ze-CFRP ne-aluminium, enye yezinsimbi ezilula kakhulu ezisetshenzisiwe, umcabango ojwayelekile uwukuthi isakhiwo se-aluminium samandla alinganayo cishe singaba nesisindo esiphindwe izikhathi ezingu-1.5 kunesakhiwo se-carbon fiber.
Yiqiniso, kunezinhlobonhlobo eziningi ezingashintsha lesi siqhathaniso. Ibanga kanye nekhwalithi yezinto zokwakha zingahluka, futhi ngezinhlanganisela, iinqubo yokukhiqiza, i-fiber architecture, kanye nekhwalithi kufanele kucatshangelwe.
Ukungalungi kwe-CFRP Composites
Izindleko:Nakuba izinto ezimangalisayo, kunesizathu sokuthi kungani i-carbon fiber ingasetshenziswa kuzo zonke izinhlelo zokusebenza. Okwamanje, izinhlanganisela ze-CFRP zibiza izindleko ezimweni eziningi. Ngokuya ngezimo zemakethe zamanje (ukunikezwa kanye nesidingo), uhlobo lwe-carbon fibre (i-aerospace vs. grade grade), kanye nosayizi we-fiber tow, intengo ye-carbon fiber ingahluka kakhulu.
I-carbon fibre eluhlaza ngesisekelo senani ngephawundi ngalinye ingaba noma kuphi phakathi kwezikhathi ezi-5 ukuya kwezingu-25-izikhathi ezibiza kakhulu kune-fiberglass. Lokhu kungafani kukhulu nakakhulu uma kuqhathaniswa insimbi nezinhlanganisela ze-CFRP.
I-Conductivity:Lokhu kungaba yinzuzo kokubili kuzinhlanganisela ze-carbon fibre, noma kube kubi kuye ngohlelo lokusebenza. I-Carbon fiber i-conductive ngokwedlulele, kuyilapho i-glass fiber i-insulative. Abaningiizicelo zisebenzisa ingilazi fiber, futhi ayikwazi ukusebenzisa i-carbon fiber noma insimbi, ngenxa nje ye-conductivity.
Isibonelo, embonini yezinsiza, imikhiqizo eminingi iyadingeka ukusebenzisa imicu yengilazi. Futhi kungesinye sezizathu zokuthi kungani amaladi asebenzisa i-glass fiber njengama-ladder rails. Uma isitebhisi se-fiberglass singathintana nentambo yamandla, amathuba okuba ugesi anciphe kakhulu. Lokhu bekungeke kube njalo ngeladi le-CFRP.
Nakuba izindleko zezinhlanganisela ze-CFRP zisalokhu ziphezulu, intuthuko entsha yezobuchwepheshe kwezokukhiqiza iyaqhubeka ivumela imikhiqizo eyonga kakhulu. Ngethemba, esikhathini sethu sokuphila, sizokwazi ukubona i-carbon fiber ebiza kakhulu esetshenziswa ezinhlobonhlobo zabathengi, izimboni, kanye nezicelo zezimoto.
