Cov khoom siv txhawb zog yog cov pob txha txhawb nqa ntawm FRP cov khoom, uas pib txiav txim siab lub zog ntawm cov khoom pultruded.Kev siv cov khoom siv txhawb zog kuj muaj qee yam cuam tshuam rau kev txo qis ntawm cov khoom lag luam thiab ua kom cov thermal deformation kub thiab kub tsis tshua muaj zog.
Hauv kev tsim cov khoom lag luam FRP, kev xaiv cov khoom siv ntxiv yuav tsum xav txog cov txheej txheem molding ntawm cov khoom, vim hais tias hom, txheej txheej thiab cov ntsiab lus ntawm cov khoom siv txhawb zog muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm FRP cov khoom, thiab lawv pib txiav txim siab lub tshuab. lub zog thiab elastic modulus ntawm FRP cov khoom.Kev ua tau zoo ntawm cov khoom siv pultruded siv cov khoom siv sib txawv kuj sib txawv.
Tsis tas li ntawd, thaum ua tau raws li qhov yuav tsum tau ua ntawm cov khoom lag luam ntawm cov txheej txheem molding, tus nqi yuav tsum tau txiav txim siab, thiab cov khoom siv hluav taws xob pheej yig yuav tsum tau xaiv ntau li ntau tau.Feem ntau, qhov untwisted roving ntawm iav fiber ntau yog qis dua tus nqi ntawm fiber ntau;tus nqi ntawm kev xav yog qis dua li ntawm daim ntaub, thiab lub impermeability yog qhov zoo., tab sis lub zog tsawg;alkali fiber ntau yog pheej yig dua li alkali-dawb fiber ntau, tab sis raws li cov ntsiab lus alkali nce, nws cov alkali tsis kam, corrosion kuj, thiab cov khoom hluav taws xob yuav poob qis.
