Cov bats sib xyaw feem ntau yog tsim los ntawm cov tub ntxhais sab hauv ntawm cov pa roj carbon fiber ntau sib txuas nrog txheej txheej ntawm siab - lub zog yas. Qee lub sij hawm lawv raug hu ua "compressed bats," "synthetic bats," los yog "bamboo bats." Vim tias cov puav pheej sib xyaw ua ke ua ke qhov zoo ntawm ob qho tib si ntoo thiab txhuas bats - muab kev ua haujlwm zoo dua thiab tsis kam ua kom tawg -lawv lub zog sib tsoo yog piv rau, yog tias tsis sib npaug, uas ntawm txhuas bats. Yog li ntawd, lawv feem ntau txwv tsis pub hauv kev sib tw thoob ntiaj teb. Txawm li cas los xij, nyob rau hauv lub teeb ntawm International Baseball Federation lub zog thawb los hloov tag nrho cov kev sib tw thoob ntiaj teb rau kev siv tshwj xeeb ntawm cov puav ntoo, cov puav puav leej tau raug suav tias yog ib qho kev hloov pauv uas cuam tshuam qhov sib txawv ntawm txhuas thiab ntoo. Yog li ntawd, lawv siv qee zaus tso cai hauv kev sib tw "peb-tier" baseball (xws li cov hluas, tsev kawm ntawv theem siab, thiab qib siab). Tsis tas li ntawd, hauv qee qhov kev sib tw hauv cheeb tsam hauv Nyij Pooj lub tsev kawm qib siab hauv baseball, kev siv cov puav puav pheej tseem tso cai. Cov bats niaj hnub ua kom muaj kev vibration tsawg dua thaum muaj kev cuam tshuam thiab ua kom muaj qhov loj dua "qab zib" (qhov zoo tshaj plaws hitting cheeb tsam); Txawm li cas los xij, lawv feem ntau xav tau lub sijhawm "so{11}}hauv" kom ua tiav lawv qhov kev ua tau zoo.
Aluminium bats yog tsim los ntawm hlau, nrog aluminium nws tus kheej ua cov khoom tseem ceeb. Txawm li cas los xij, txij li cov txhuas ntshiab yog cov hlau uas tsis muaj qhov tawv txaus, cov pob tawb baseball yeej tsis tsim los ntawm cov ntshiab txhuas ib leeg; Hloov chaw, lawv feem ntau yog tsim los ntawm aluminium alloys. Aluminium alloy bats yuav tsum tsis txhob tawg - nyob rau hauv lub sij hawm thiab muaj superior durability; conversely, lawv feature ib tug me me qhov chaw qab zib, thiab nto ntawm tus puav taub hau tej zaum yuav pom cov cim ntawm hnav thiab puas tom qab siv ntev. Kev siv cov txhuas bats tau poob qis tsis tu ncua thiab tam sim no zoo li tsis hnov txog hauv kev sib tw loj thoob ntiaj teb; Txawm li cas los xij, lawv tseem tuaj yeem pom qee zaus hauv peb lub tebchaws peb-tier baseball kev sib tw.
Carbon fiber ntau baseball puav yog crafted siv carbon fiber composite cov ntaub ntawv. Cov txheej txheem tsim khoom feem ntau suav nrog immersing bundles ntawm carbon fiber yarn nyob rau hauv ib tug epoxy resin tov, weaving lawv mus rau hauv ib tug carbon ntaub, thiab ces qhwv no ntaub nyob ib ncig ntawm ib tug mandrel (ib tug cylindrical pwm). Cov puav yog tom qab tsim los ntawm ntau cov kauj ruam suav nrog kev ci, siab -siab molding, pleev xim, thiab ntsuas qhov hnyav. Cov khoom siv carbon fiber ntau muab cov khoom sib txawv ntawm qhov zoo, nrog rau kev tsim kho lub teeb, lub zog tshwj xeeb, kev ua haujlwm zoo, thiab kev ua kom zoo dua qub.
