Hom thiab cov yam ntxwv ntawm cov txheej txheem sandwich tsim tshuab hauv FRP txheej txheem ntau lawm

Kev noj qab haus huv thiab kev tsim kho kom ruaj khov ntawm txhua qhov kev lag luam yog qhov tsim nyog rau kev txhim kho ruaj khov ntawm tag nrho cov kev lag luam saw. Kev noj qab haus huv thiab kav ntev ntawm cov khoom siv sib xyaw ua ke (iav fiberreinforced yas) kev lag luam yuav tsum tau ua raws li kev noj qab haus huv thiab kav ntev ntawm nws cov iav fiber ntau thiab unsaturated polyester resin industries. Kev lag luam iav fiber ntau tau ua tiav kev lag luam kev sib koom ua ke, tsim lub ntiaj teb-chav sib tw suav thaj chaw kev lag luam, thaum kev lag luam tsis muaj dej tsis txaus tau nyuam qhuav ncaws tawm kev lag luam rov tsim dua tshiab, thiab cov kev hloov pauv tom ntej tseem yuav ua rau muaj txiaj ntsig zoo rau kev lag luam cov ntaub ntawv sib xyaw. muaj kev cuam tshuam loj heev.

Sandwich vaj huam sib luag feem ntau yog ua los ntawm peb txheej ntawm cov khoom. Cov khaubncaws sab nraud povtseg sab saud thiab qis ntawm cov khoom siv sib xyaw ua ke yog cov khoom siv muaj zog thiab cov khoom siv high-modulus, thiab cov txheej nruab nrab yog cov khoom siv hnyav dua. CovFRP Sandwich qauvQhov tseeb yog ib qho kev sib xyaw ua ke ntawm cov ntaub ntawv sib xyaw thiab lwm yam khoom siv hnyav. Kev siv cov qauv sandwich yog los txhim kho kev siv cov ntaub ntawv zoo thiab txo qhov hnyav ntawm cov qauv. Noj beam-slab Cheebtsam ua piv txwv, nyob rau hauv tus txheej txheem ntawm kev siv, nws yog tsim nyog los ua kom tau raws li qhov yuav tsum tau ntawm lub zog thiab rigidity. Cov yam ntxwv ntawm FRP cov ntaub ntawv yog siab zog, Modulus yog tsawg. Yog li ntawd, thaum ib lub iav fiber ntau siv cov khoom siv yas siv los ua cov kab thiab slabs kom tau raws li qhov yuav tsum tau muaj zog, qhov deflection feem ntau loj. Yog tias tus qauv tsim raws li qhov kev tso cai deflection, lub zog yuav ua tau zoo heev, ua rau khib nyiab. Tsuas yog los ntawm kev siv tus qauv ntawm cov qauv sandwich tuaj yeem daws qhov kev tsis sib haum xeeb no. Qhov no kuj yog qhov laj thawj tseem ceeb rau kev txhim kho ntawm cov qauv sandwich.

Vim lub zog siab, lub teeb yuag, siab rigidity, corrosion kuj, hluav taws xob rwb thaiv tsev thiab microwave kis tau tus mob ntawm FRP sandwich qauv, nws tau dav siv nyob rau hauv aircraft, missiles, spacecraft thiab qauv, ru tsev panels nyob rau hauv aviation kev lag luam thiab aerospace kev lag luam. Txo qhov hnyav ntawm lub tsev thiab txhim kho kev siv. Lub pob tshabiav fiberreinforced yas sandwich vaj huam sib luag tau dav siv nyob rau hauv lub teeb pom kev zoo ru tsev ntawm industrial nroj tsuag, loj pej xeem vaj tse thiab tsev xog paj nyob rau hauv lub txias cheeb tsam. Hauv kev tsim cov nkoj tsim thiab kev thauj mus los, FRP sandwich vaj huam sib luag tau siv dav hauv ntau yam hauv FRP submarines, minesweepers, thiab yachts. FRP cov neeg taug kev txuas hniav, txoj kev loj choj, tsheb thiab tsheb ciav hlau, thiab lwm yam. tsim thiab tsim nyob rau hauv kuv lub teb chaws txhua tus txais yuav FRP sandwich qauv, uas ua tau raws li ntau yam kev ua tau zoo ntawm lub teeb yuag, siab zog, siab rigidity, rwb thaiv tsev kub thiab kev txuag hluav taws xob. Hauv lub npog xob laim uas yuav tsum muaj kev sib kis ntawm microwave, FRP sandwich qauv tau dhau los ua cov khoom tshwj xeeb uas lwm cov ntaub ntawv tsis tuaj yeem sib piv nrog.
