Thaum nws los txog ntawm cov xov hlau, peb thawj zaug xav txog tooj liab xov hlau, txhuas hlau, hlau hlau thiab lwm yam hlau hlau.Lawv tag nrho yog ua los ntawm ntshiab hlau hlau kos duab.Qhov laj thawj yog vim li cas hlau siv yog tias txhua cov hlau muaj hluav taws xob zoo.Qhov laj thawj vim li cas cov hlau muaj hluav taws xob zoo yog vim cov hlau atoms muaj tsawg dua cov hluav taws xob sab nraud.Tom qab lawv tau muab tso ua ke rau hauv pawg atomic, txheej txheej ntawm txhua lub atom kuj muaj ib lossis ob lub electrons thiab tig ib ncig ntawm nws, yog li cov txheej txheej ntawm lub atom tsuas muaj ib lossis ob lub electrons xwb.Yuav muaj ntau lub tshuab hluav taws xob nyob hauv txheej, yog li cov hluav taws xob txawv teb chaws tuaj yeem nkag tau yooj yim thiab txav mus los, thiab cov hlau yog yooj yim los ua hluav taws xob, yog li cov xov hlau peb tau pom yog cov hlau.
Vim qhov zoo conductivity ntawm hlau, cov xov hlau tam sim no yog cov hlau.Cov xov hlau puas tuaj yeem hloov tau los ntawm lwm cov ntaub ntawv tsis sib cuag?Kuj ua tau, zoo li carbon fiber.
Ntau tus phooj ywg paub tias cov pa roj carbon fiber ntau yog tawv heev, tab sis lawv tsis paub tias qee cov carbon fibers yog cov khoom siv hluav taws xob.Qhov no yog vim hais tias xws li fibers muaj ib tug atomic qauv zoo ib yam li graphite, thiab graphite yog ib tug zoo conductor, uas yog ib yam ntawm cov ntsiab lus carbon.Allotropes, txhua cov pa roj carbon atom hauv graphite txuas nrog peb lwm cov pa roj carbon atom nyob ib ncig ntawm nws, teem rau hauv cov qauv honeycomb zoo li hexagonal, uas txhua cov pa roj carbon atom emits ib qho hluav taws xob dawb, yog li graphite ua hluav taws xob.Qhov kev ua tau zoo heev, kwv yees li 100 npaug ntau dua li cov khoom siv tsis yog hlau.
Txawm li cas los xij, txawm li cas los xij, qhov kev coj ua tam sim no hauv cov pa roj carbon fiber ntau tsis yog nyob ntawm cov pa roj carbon fiber ntau, vim tias cov pa roj carbon fiber conductivity tseem tsis zoo li cov hlau.Cov resin integrates cov longitudinally teem carbon fiber filaments rau hauv ib tug tag nrho, uas ua rau cov carbon fiber tsawg conductive, yog li cov pa roj carbon fiber ntawm no tsis yog siv los ua hluav taws xob, tab sis kom hnyav.Cov qauv ntawm cov carbon fiber puas core hlau yog zoo ib yam li cov pa steel-cored aluminium stranded hlau.Nws kuj tau muab faib ua cov tub ntxhais hlau sab hauv thiab cov hlau nplaum saum npoo.Cov tub ntxhais hlau dais feem ntau ntawm cov neeg kho tshuab kev nyuaj siab ntawm cov hlau nws tus kheej, thaum lub txhuas hlau sab nrauv bears tam sim no khiav hauj lwm.
Nws hloov tawm hais tias lub load-bearing xov hlau nyob rau hauv cov xov hlau yog tag nrho cov hlau hlau, feem ntau steel hlau ropes twisted los ntawm 7 strands ntawm steel hlau, thiab sab nraud yog ib tug txhuas hlau uas muaj li ntawm kaum ob strands ntawm txhuas hlau, tab sis cov carbon fiber puas. cov khoom siv hlau yog nruab nrab strand ntawm carbon fiber ntau cov khoom, thiab sab nraud yog quadrilateral.Multi-strand aluminium hlau, raws li qhia hauv daim duab hauv qab no, sab laug yog cov hlau hlau txhuas hlau, thiab sab xis yog cov carbon fiber ntau cov tub ntxhais hlau.
Peb paub tias cov hlau muaj lub zog zoo huv si thiab tawv, nws qhov ceev heev, tab sis nws yog qhov hnyav heev, thiab nws qhov hnyav yog tib yam nkaus xwb ntim.Txawm li cas los xij, lub zog tensile thiab toughness ntawm carbon fiber zoo dua li cov hlau, feem ntau tsawg kawg yog ob zaug ntawm tensile quab yuam ntawm hlau, yog li lub hom phiaj tseem ceeb ntawm kev siv cov khoom siv carbon fiber ntau yog txo qhov hnyav ntawm cov hlau, thiab tib lub thickness. ntawm cov pa roj carbon fiber ntau Vim tias qhov rub tau zoo dua, nws tuaj yeem nqa tau ntau dua txhuas hlau, ua rau cov hlau los yog cable thicker kom dhau tam sim no.
Txij li thaum cov roj carbon fiber ntau hlau muaj cov yam ntxwv zoo tshaj plaws ntawm qhov tsis tshua muaj siab, lub teeb yuag, lub zog tensile loj thiab muaj zog toughness, yog tias cov khoom siv no tuaj yeem siv tau ntev, nws zoo li yuav hloov cov hlau hlau thiab txhuas hlau hauv. yav tom ntej.Cov hlau uas nquag siv, thiab cov pa roj carbon fiber ntau muaj cov cua sov thaum nws muaj zog, yog li nws kuj tseem yuav siv los ua cov cua sov hlau hauv qee qhov kev lag luam.Yog li ntawd, cov hlau tam sim no tsis tas yuav yog hlau, thiab cov hlau tsis yog hlau kuj tseem yuav tshwm sim ntau dua.
