Dab tsi yog 5 piv txwv ntawm cov khoom sib xyaw?

Composites yog ib feem tseem ceeb ntawm niaj hnub engineering thiab kev tsim khoom, muab ntau yam zoo vim lawv cov khoom sib xyaw tshwj xeeb. Ib hom khoom siv sib xyaw uas tau txais kev saib xyuas ntau yog cov khoom siv fiber ntau, uas yog tsim los ntawm kev sib txuas ob lossis ntau cov khoom sib txawv los tsim cov ntaub ntawv tshiab nrog cov khoom zoo. Cov fibers no tau siv ntau yam kev siv, los ntawm aerospace thiab tsheb mus rau kev tsim kho thiab cov khoom ua si.

Composite fibers yog tsim los ntawm kev sib txuas cov ntaub ntawv xws li basalt, carbon, iav thiab aramid fibers nrog cov khoom siv matrix xws li epoxy lossis polyester resin. Qhov kev sib xyaw ua ke no ua rau cov khoom siv muaj zog, sib zog thiab ruaj khov dua li cov khoom siv niaj hnub. Ib qho piv txwv ntawm cov khoom siv fiber ntau yog HB171C basalt fiber, uas paub txog nws lub zog siab, kub tsis kam, thiab tshuaj lom neeg. Qhov no ua rau nws zoo tagnrho rau kev siv hauv tsheb thiab kev tsim kho kev lag luam.

Thaum nws los txog rau cov ntaub ntawv sib xyaw, muaj ntau yam piv txwv uas qhia tau hais tias muaj ntau yam thiab ua tau zoo ntawm cov ntaub ntawv no. Tsib piv txwv ntawm cov ntaub ntawv muaj xws li carbon fiber reinforced polymer (CFRP), fiberglass reinforced yas (FRP), aramid fiber reinforced polymer (AFRP), ntoo yas composite (WPC), thiab hlau matrix composite (MMC) ). Txhua yam ntawm cov ntaub ntawv no muaj cov khoom tshwj xeeb thiab qhov zoo, ua rau lawv haum rau ntau yam kev siv.

Hauv cov ntsiab lus ntawm kev sib xyaw fibers, nruam chopped fibers yog tshwj xeeb tshaj yog pab tau rau kev sib txhuam thiab kev siv txoj kev. Cov fibers yog tsim los ua kom muaj zog thiab ua haujlwm ntev ntawm cov ntaub ntawv sib txhuam siv hauv tsheb nres tsheb nrog rau cov khoom siv hauv kev. Los ntawm kev sib xyaw cov fibers sib xyaw rau hauv cov ntawv thov no, cov tuam txhab tsim khoom tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm lawv cov khoom, thaum kawg tsim cov khoom muaj kev nyab xeeb thiab txhim khu kev qha.

Zuag qhia tag nrho, cov fibers puas ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub peev xwm ntawm ntau yam kev lag luam, muab ntau yam txiaj ntsig xws li muaj zog ntxiv, txo qhov hnyav thiab txhim kho kev tiv thaiv ib puag ncig. Raws li kev siv thev naus laus zis txuas ntxiv mus, kev txhim kho thiab kev siv cov fibers sib xyaw yuav tsum ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm engineering thiab kev tsim khoom.
