Cov khoom siv fiber ntau ntev yog dab tsi?
Cov khoom siv fiber ntau ntev, tseem hu ua ntev fiber reinforced thermoplastic (LFRT) puas, yog ib hom khoom sib xyaw uas txuas ntxiv, ntev, thiab unidirectional fibers tau kos rau hauv cov thermoplastic matrix. Qhov no ua rau cov khoom muaj zog tshwj xeeb, nruj, thiab toughness. Cov khoom no tau dhau los ua neeg nyiam vim kev nce qib hauv nws cov cuab yeej tsim khoom thiab nws cov khoom tshwj xeeb.
Kev tsim cov khoom siv fiber ntau ntev nrog cov txheej txheem hu ua long-fiber thermoplastic-Granules (LFT-G) txhaj tshuaj molding. Cov txheej txheem no suav nrog melting thiab sib tov ntawm thermoplastic resin thiab ntev fiber reinforcement, thiab txiav cov composite rau granules, tom qab ntawd txhaj rau hauv pwm. LFT-G txhaj tshuaj molding muaj cov khoom zoo dua piv rau cov tsoos luv-fiber composites, nrog rau kev nruj dua, muaj zog tiv thaiv, thiab txhim kho qhov ruaj khov.
Cov khoom siv fiber ntau ntev yog feem ntau siv hauv kev lag luam xws li tsheb, aerospace, thiab cov khoom ua si. Hauv kev tsim tsheb, cov khoom siv yog siv rau cov khoom siv xws li lub qhov rooj vaj huam sib luag, fender liners, thiab lub cev lub cev. Kev lag luam aerospace siv cov khoom siv no rau cov qauv sib xyaw, xws li cov khoom siv tis thiab cov fuselages. Tsis tas li ntawd, cov tuam txhab ua kis las kuj tau txais cov khoom siv los siv rau hauv cov khoom siv hnyav thiab cov khoom siv ruaj khov xws li tennis rackets thiab golf clubs.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv fiber ntau ntev yog nws cov nqi qis dua piv rau cov tsoos carbon fiber ntau. Cov khoom siv fiber ntau ntev yog qhov yooj yim rau kev tsim khoom thiab tuaj yeem tsim tau ntau qhov ntau, ua rau nws muaj kev xaiv pheej yig dua rau ntau yam kev siv.
Tnws cov khoom ntawm cov khoom siv fiber ntau ntev kuj tuaj yeem hloov kho tau zoo, nyob ntawm qhov xav tau kawg-siv daim ntawv thov. Hom thiab kev taw qhia ntawm fibers, nrog rau kev xaiv ntawm thermoplastic matrix, tuaj yeem hloov kho kom zoo tshaj plaws raws li qhov xav tau ntawm ib daim ntawv thov tshwj xeeb. Qhov no ua rau cov khoom siv nrog lub zog tshwj xeeb thiab ua haujlwm ntev uas tuaj yeem tsim kho kom tau raws li qhov xav tau ntawm ntau yam kev lag luam.
Cov khoom siv fiber ntau ntev yog cov khoom siv sib xyaw ua ke nrog cov khoom zoo tshaj plaws uas ua rau nws muaj kev xaiv zoo rau ntau yam kev lag luam xws li tsheb, aerospace, thiab cov khoom ua si. Kev nce qib hauv nws cov thev naus laus zis tsim khoom tau ua rau nws muaj txiaj ntsig zoo rau cov khoom siv carbon fiber ntau rau ntau daim ntawv thov. Nws cov khoom tshwj xeeb, nrog rau nws cov txiaj ntsig zoo thiab kev hloov kho, yuav muab LFT cov khoom siv ntau dua los daws cov kev xav tau siab ntawm cov chaw tsim khoom.
