los ntawm 1958, tus kws tshawb fawb Roger Bacon tau pom tias nyob rau hauv cov xwm txheej tshwj xeeb, pib nrog qee cov khoom siv carbon, cov pa roj carbon zoo "stubbles" tuaj yeem ua rau ntawm cov txheej txheem ua kom sov. Tau ntau xyoo, cov kws tshawb fawb tuaj yeem ua cov xov paj carbon fiber ntau uas tuaj yeem sib txuas ua ke rau hauv cov ntawv.
Raws li txoj cai, thaum tib neeg sib tham txog "carbon fiber" yog siv nyob rau hauv lub tsheb tam sim no, lawv tab tom tham txog carbon-fiber strands uas yog woven thiab muab tso rau hauv cov pos hniav. Tom ntej no, qhov no carbon-fiber composite, ntawm no thiab muaj hu ua carbon fiber reinforced yas (CFRP), yog molded raws li xav tau. Thaum lub suab teeb tsa, koj muaj lub tsheb sib tw uas tau txais nws qhov zoo los ntawm cov khoom zoo sib xws uas ua rau lub pob zeb muaj nuj nqis.
cov lus qhia ua kom cov ntawv hlau siv rau cov neeg tsim tsheb kom 'ntau dua hauv av', yog li ntawd, lub tsheb tuaj yeem ruaj ntseg dua siv lawv cov khoom. Thaum lub sijhawm ntawd, thaum kuv nug tias nws txhais li cas tiag thaum lawv hais tias lawv cov hlau txhim kho yog 'ntau dua hauv av' dua li cov hlau zoo tib yam, thiab lawv cov lus teb yog ntau dua modulus. Supposedly, zoo, Young's modulus, thiab sturdiness yog qhov txawv. Qhov zoo txhais tau tias nws tuaj yeem tiv taus tsav ntau dua ua ntej cov yas distortion, Young's modulus lossis solidness implies nws twists tsawg dua rau lub zog zoo sib xws, Toughness implies tseem ceeb heev rau disfigure nws.
Ib yam li ntawd, cov pa roj carbon fiber ntau, hauv daim ntawv thov raug, yog cov khoom siv zoo: nws yog ib qho khoom siv thiab lub teeb, thiab koj tuaj yeem npaj qhov zoo tomahawks koj xav tau rau hauv cov khoom los ntawm qhov uas koj paub txog cov fiber ntau hauv nruab nrab ntawm nteg. Piv txwv li, koj muaj ob yam khoom, indistinguishable sab hauv thiab tawm ib sab ntawm cov khoom: ib tug yog hlau, lwm yam carbon fiber. Thaum lub sij hawm cov hlau tawm tsam luv luv, nws yuav disfigure ntawm no thiab muaj; nws yuav yog nkhaus los yog smash. Amid nws disfigurement, nws yuav nthuav tawm qhov tseem ceeb. Thaum lub sij hawm thaum carbon fiber ntog, nws tawg mus rau hauv me ntsis bitty pieces uas ingest tsis muaj dab tsi.
