Fiberglass Plus Textile los pab lub Spacecraft ya mus rau qhov chaw

Thaum Lub Ib Hlis 17, 2024, Tianzhou VII cargo spacecraft tau xa ib pawg ntawm cov khoom siv nyob thiab cov cuab yeej sim mus rau qhov chaw nres tsheb. Nws hloov tawm hais tias lub hnub ci tis substrate ntawm Tianzhou cargo spacecraft yog ib qho xav tsis thoob li, nrog rau ib qho kev nthuav dav. fiberglass meshqauv uas zoo li ib tug tennis racket.
Raws li cov lus ceeb toom, Tianzhou cargo spacecraft yog ib tug semi-rigid solar tis, lub hnub ci tis ntawm ciam teb rau lub carbon fiber ntau, qhov nruab nrab ntawm cov fiberglass mesh muaj li ntawm mesh, zoo ib yam li tennis racket, lub hnub ci cell hlais yog hooked ntawm lubfiberglass mesh. Cov iav fiber ntau mesh qauv no, nrog rau cov yam ntxwv ntawm lub teeb yuag, thiab qhov chaw qis qis ntawm atomic oxygen, plasma muaj kev tiv thaiv zoo dua.
Qhov chaw muaj ntau cov atomic oxygen muaj nyob, lub peev xwm oxidation muaj zog heev, yog li cov ntaub ntawv organic polymer yog oxidized ntau heev, yog li xaiv cov khoom muaj peev xwm antioxidant siab heev, peb xaiv cov khoom siv hauv cov iav fiber ntau. Cov iav fiber ntau muaj qhov zoo ntawm antioxidant, lub teeb yuag thiab lwm yam. Tab sis nws yog ib qho nyuaj heev los sim weave net nrog iav fiber.
Tab sis iav fiber kuj muaj qhov tsis muaj zog loj heev, nws qhov kev ua haujlwm ntawm cov ntaub yog qhov tsis zoo, vim nws yog nkig heev. Cov ntaub ntawv textile thiab fiber ntau zoo sib xws, cov fiber ntau zoo dua, qhov yooj yim heev. Los ntawm kev sib tw cov fiber ntau, nws dhau los ua cov khoom siv ntxhib heev uas tuaj yeem ua kom tiav lub hom phiaj. Nws kuj muaj ob peb qhov zoo: nws yog lub teeb yuag, thiab nws yog tag nrho cov mesh, yog li nws muaj peev xwm txuas hnub ci vaj huam sib luag rau nws.
Tom qab cov iav fiber ntau yog woven rau hauv substrate ntawm lub hnub ci sail vaj huam sib luag, nws kuj yog coated nrog resin los txhim kho nws cov kev ua tau zoo. Cov resin feem ntau yog ua kom lub ntsej muag flatter, tab sis kuj muab kev tiv thaiv zoo. Vim hais tias ntawm no hom resin zoo li silicone, nws yog ntau resistant rau qhov chaw ib puag ncig, thiab stability thiab abrasion kuj tseem tuaj yeem txhim kho, tag nrho cov kev ua tau zoo tuaj yeem txhim kho tau zoo heev.----iav Fiber Information Network
