Nyob rau hauv lub ntiaj teb no ntawm cyclists, carbon fiber thiab steel ncej tsheb kauj vab yog ob qho kev xaiv. Ob hom tsheb no muaj lawv tus kheej qhov zoo, ua rau cov neeg caij tsheb inevitably xav tsis thoob thaum xaiv. Tom ntej no, peb yuav delve rau hauv cov yam ntxwv ntawm ob hom khoom siv tsheb los pab koj txiav txim siab paub ntau ntxiv.
Cov yam ntxwv ntawm Carbon Fiber thiab Steel Ncej Tsheb
Qhov zoo thiab ceev faj ntawm carbon fiber thav duab
Carbon fiber ua lub luag haujlwm tseem ceeb hauv kev tsim tsheb kauj vab vim nws lub teeb yuag thiab lub zog siab. Txawm li cas los xij, thaum yuav khoom, tus nqi thiab kev saib xyuas yuav tsum tau txiav txim siab, thiab kev saib xyuas kom zoo yuav tsum tau ua thaum caij tsheb kom tsis txhob muaj qhov kub thiab txias thiab UV puas. Tsis tas li ntawd, carbon fiber thav duab yog qhov ua tsis tau zoo nyob rau hauv cov nqe lus ntawm lateral compressive zog, ua rau lawv lub zog tsim ib qho tseem ceeb technology. Cov pa roj carbon fiber ntau tau dhau los ua ib feem tseem ceeb ntawm kev lag luam tsheb kauj vab vim lawv cov kev ua tau zoo thiab cov yam ntxwv sib zog. Tom qab nkag siab txog kev ua tau zoo thiab kev siv cov pa roj carbon fiber ntau, thaum xaiv cov pa roj carbon fiber ntau, nws yog ib qho tseem ceeb uas yuav tau xyuam xim rau qee qhov teeb meem tseem ceeb, xws li tus nqi, tus nqi tu, thiab kev xav tau ntawm tus kheej. Kev xaiv tus ncej tsim nyog yog qhov tseem ceeb rau ntau hom kev caij tsheb.
Cov khoom siv carbon fiber ntau muaj kev faib tawm thiab kev tsim khoom sib txawv. Cov pa roj carbon fiber tsis yog cov pa roj carbon ntshiab, tab sis yog cov khoom siv tshiab nrog cov ntsiab lus carbon ntau dua 95%. Feem ntau ua rau carbon fiber filaments, hu ua 'carbon monofilaments'. Cov monofilaments no yuav muab sib sau ua ke thiab woven rau hauv cov ntaub ntawv carbon fiber rau siv. Kev faib tawm ntawm cov pa roj carbon fiber ntau suav nrog T1000, M40, thiab lwm yam, nrog T series tsom rau lub zog thiab M series ntawm elasticity. Sab saum toj carbon fiber tam sim no siv hauv kev lag luam tsheb kauj vab yog T1000.
Lub teeb yuag thiab nyuaj zog ntawm carbon fiber yog tus kheej - pov thawj. Txawm hais tias cov pa roj carbon fiber ntau nyuaj, nws tseem tuaj yeem tsim ib lub thav duab nrog kev ua haujlwm zoo ntawm kev poob siab. Qhov no yog vim qhov zoo tensile kev ua tau zoo ntawm carbon fiber filaments. Txawm li cas los xij, nws muaj qhov tsis muaj zog ntawm sab nraud compression tsis muaj zog, uas yog vim li cas lub thav duab nyuaj yog nquag tawg hauv kev sib tsoo.
Rau kev txij nkawm ntawm carbon fiber thav duab, txawm hais tias kho tuaj yeem ua tau, nws yog ib qho nyuaj kom tau txais pre-impregnated unidirectional carbon daim ntaub siv los ntawm thawj lub Hoobkas, ua kom muaj tseeb kev kho kom yooj yim dua. Thaum lub sij hawm tu txhua hnub, vim qhov rhiab heev ntawm cov pa roj carbon fiber ntau rau qhov kub thiab txias thiab ultraviolet hluav taws xob, nws yog ib qho tsim nyog yuav tsum khaws cia hauv qhov tsaus ntuj thiab qhov kub thiab txias kom ntev nws lub neej kev pab cuam. Thaum thauj khoom, kev zawm ntawm cov ntsia hlau yuav tsum ua raws li cov kev qhia tshwj xeeb los tiv thaiv kev puas tsuaj los ntawm kev nruj nruj heev.
