Cov qauv sandwich feem ntau yog cov khoom sib xyaw ua los ntawm peb txheej ntawm cov khoom. Cov txheej sab saud thiab sab hauv qab ntawm cov khoom sib xyaw sandwich yog cov khoom muaj zog thiab cov khoom siv modulus siab, thiab txheej nruab nrab yog cov khoom siv tuab dua thiab sib dua. Cov qauv sandwich FRP yog qhov tseeb yog kev sib xyaw ua ke ntawm cov khoom sib xyaw thiab lwm cov khoom siv sib dua. Cov qauv sandwich yog siv los txhim kho kev siv cov khoom siv zoo thiab txo qhov hnyav ntawm cov qauv. Piv txwv li, siv cov khoom beam-slab, thaum siv, nws yog qhov tsim nyog los ua kom tau raws li qhov yuav tsum tau ua ntawm lub zog thiab kev nruj. Cov yam ntxwv ntawm cov iav fiber reinforced plastics yog lub zog siab, Modulus yog qis. Yog li ntawd, thaum siv ib qho iav fiber reinforced plastics los ua beams thiab slabs kom tau raws li qhov yuav tsum tau ua ntawm lub zog, qhov deflection feem ntau loj heev. Yog tias tus qauv tsim yog raws li qhov deflection tso cai, lub zog yuav raug tshaj dhau heev, ua rau muaj kev pov tseg. Tsuas yog los ntawm kev siv tus qauv sandwich thiaj li daws tau qhov kev tsis sib haum xeeb no. Qhov no kuj yog qhov laj thawj tseem ceeb rau kev txhim kho cov qauv sandwich.
Vim yog lub zog siab, lub teeb yuag, siab rigidity, corrosion tsis kam, hluav taws xob rwb thaiv tsev thiab microwave kis tau los ntawm FRP sandwich qauv, nws tau siv dav hauv dav hlau, foob pob hluav taws, spacecraft thiab cov qauv, ru tsev vaj huam sib luag hauv kev lag luam aviation thiab kev lag luam aerospace. Txo qhov hnyav ntawm lub tsev thiab txhim kho kev siv. Lub pob tshab iav fiber reinforced yas sandwich vaj huam sib luag tau siv dav hauv lub teeb pom kev zoo ntawm cov nroj tsuag kev lag luam, cov tsev pej xeem loj thiab cov tsev cog khoom hauv thaj chaw txias. Hauv kev tsim nkoj thiab kev thauj mus los, FRP sandwich qauv tau siv dav hauv ntau yam khoom hauv FRP submarines, minesweepers, thiab yachts. Cov choj neeg taug kev FRP, cov choj txoj kev loj, tsheb thiab tsheb ciav hlau, thiab lwm yam tsim thiab tsim hauv kuv lub tebchaws txhua tus txais yuav FRP sandwich qauv, uas ua tau raws li ntau yam kev xav tau ntawm lub teeb yuag, lub zog siab, siab rigidity, rwb thaiv tsev kub thiab kev khaws cia kub. Hauv lub npog xob laim uas xav tau microwave kis tau los ntawm, FRP sandwich qauv tau dhau los ua cov khoom siv tshwj xeeb uas lwm cov ntaub ntawv tsis tuaj yeem piv nrog.
