Cov roj carbon fiberLub thawv cua sov sib xyaw ua ke yog lub thawv nyias nyias uas muaj lub liner kaw ruaj khov thiab lub txheej fiber-wound muaj zog heev, uas feem ntau yog tsim los ntawm cov txheej txheem winding thiab weaving fiber. Piv nrog rau cov thawv hlau ib txwm muaj, lub liner ntawm cov thawv sib xyaw ua haujlwm ua qhov chaw khaws cia, kaw thiab tiv thaiv kev xeb tshuaj lom neeg, thiab cov txheej sib xyaw feem ntau yog siv los dais lub nra hnyav sab hauv. Vim yog lub zog tshwj xeeb siab thiab kev tsim qauv zoo ntawm cov khoom sib xyaw, cov thawv sib xyaw tsis yog tsuas yog txhim kho lawv lub peev xwm thauj khoom xwb, tab sis kuj txo qhov hnyav ntawm cov thawv piv rau cov thawv hlau ib txwm muaj.
Lub txheej sab hauv ntawm lub thawv siab fiber-wound feem ntau yog cov qauv liner, uas nws lub luag haujlwm tseem ceeb yog ua raws li lub sealing barrier los tiv thaiv kev xau ntawm cov pa roj siab lossis cov kua uas khaws cia sab hauv, thiab tib lub sijhawm los tiv thaiv cov txheej sab nraud fiber-wound. Cov txheej no yuav tsis raug corroded los ntawm cov khoom khaws cia sab hauv thiab cov txheej sab nraud yog cov txheej fiber-wound txhawb nqa nrog cov resin matrix, uas feem ntau yog siv los tiv thaiv feem ntau ntawm cov load siab hauv lub thawv siab.
1. Cov qauv ntawm cov hlab ntsha fiber-wound
Muaj plaub hom qauv tseem ceeb ntawm cov hlab siab sib xyaw ua ke: cylindrical, spherical, annular thiab rectangular. Lub hlab cylindrical muaj ib feem ntawm lub tog raj kheej thiab ob lub taub hau. Cov hlab siab hlau yog ua rau hauv cov duab yooj yim nrog lub zog ntau dhau hauv qhov kev taw qhia axial. Cov hlab spherical muaj kev ntxhov siab sib npaug hauv cov lus qhia warp thiab weft nyob rau hauv lub siab sab hauv thiab yog ib nrab ntawm kev ntxhov siab circumferential ntawm cov hlab cylindrical. Lub zog ntawm cov khoom siv hlau yog sib npaug hauv txhua qhov kev taw qhia, yog li lub thawv spherical ua los ntawm hlau yog tsim los rau lub zog sib npaug, thiab muaj qhov hnyav tsawg kawg nkaus thaum qhov ntim thiab siab yog qhov tseeb. Lub xeev lub zog ntawm lub thawv spherical yog qhov zoo tshaj plaws, phab ntsa lub thawv kuj tuaj yeem ua kom nyias tshaj plaws. Txawm li cas los xij, vim muaj qhov nyuaj dua hauv kev tsim cov thawv spherical, feem ntau tsuas yog siv rau hauv spacecraft thiab lwm yam sijhawm tshwj xeeb. Lub thawv nplhaib hauv kev tsim khoom lag luam yog tsawg heev, tab sis nyob rau hauv qee lub sijhawm tshwj xeeb lossis xav tau cov qauv no, piv txwv li, cov tsheb chaw kom siv tag nrho qhov chaw txwv, yuav siv cov qauv tshwj xeeb no. Lub thawv plaub fab feem ntau yog ua kom tau raws li qhov chaw tsawg, siv qhov chaw ntau tshaj plaws thiab siv cov qauv, xws li lub tsheb thauj khoom plaub fab, tsheb ciav hlau, thiab lwm yam. Cov thawv no feem ntau yog cov thawv qis-siab lossis cov thawv siab atmospheric thiab qhov zoo ntawm lub teeb dua.
Lub complexity ntawm lub structure ntawm lub tsevsib xyaw ua keLub thawv siab nws tus kheej, qhov kev hloov pauv sai ntawm qhov tuab ntawm lub taub hau thiab lub taub hau, qhov tuab thiab lub kaum sab xis ntawm lub taub hau, thiab lwm yam, coj ntau yam teeb meem rau kev tsim qauv, kev tshuaj xyuas, kev xam thiab kev txhaj tshuaj. Qee zaum, cov thawv siab sib xyaw tsis yog tsuas yog yuav tsum tau qhwv ntawm ntau lub kaum sab xis thiab qhov sib piv ceev sib txawv hauv lub taub hau, tab sis kuj yuav tsum tau siv cov txheej txheem sib txawv raws li cov qauv sib txawv. Tib lub sijhawm, qhov cuam tshuam ntawm cov yam ntxwv ua tau zoo xws li kev sib txhuam coefficient yuav tsum tau xav txog. Yog li ntawd, tsuas yog kev tsim qauv zoo thiab tsim nyog tuaj yeem coj cov txheej txheem tsim khoom ntawm cov thawv siab sib xyaw, kom tsim cov khoom sib xyaw siab sib xyaw uas ua tau raws li cov qauv tsim.
2. Cov khoom siv ntawm cov hlab ntsha fiber-qhov txhab
Raws li qhov tseem ceeb ntawm kev thauj khoom, cov txheej txheem fiber winding yuav tsum muaj lub zog siab, modulus siab, qhov ceev qis, thermal stability thiab zoo resin wettability, nrog rau kev ua haujlwm winding zoo thiab cov fiber sib xyaw nruj. Cov fiber reinforcing feem ntau siv rau cov khoom siv sib xyaw ua ke muaj xws licov fiber carbon, PBO fibers,Cov fibers polyamine uas muaj ntxhiab tsw qabthiab UHMWPE fibers.
