Cov khoom siv txhawb tau yog cov khoom siv txhawb nqa ntawm Frp cov khoom, uas tau txiav txim siab cov khoom siv tshuab ntawm cov khoom pultruded. Kev siv ntawm cov khoom siv txhawb ntxiv kuj muaj qee qhov cuam tshuam rau txo cov khoom lag luam uas txo qis ntawm cov khoom thiab ua kom lub zog tsis tshua muaj cua sov thiab kub cuam tshuam.
Hauv kev tsim ntawm Frp cov khoom lag luam, kev xaiv ntawm kev txhawb nqa cov ntaub ntawv muaj kev cuam tshuam ntawm Frp cov khoom lag luam, vim tias hom kev ua haujlwm ntawm cov khoom lag luam ntawm cov khoom lag luam, thiab cov ntsiab lus kev txiav txim siab ntawm cov khoom siv ntawm Frp cov khoom lag luam. Kev ua yeeb yam ntawm cov khoom siv pultruded siv cov khoom siv sib txawv kuj txawv.
Tsis tas li ntawd, thaum ua raws cov khoom lag luam uas yuav tsum tau ua ntawm molding txheej txheem, tus nqi yuav tsum tau txiav txim siab, thiab pheej yig ntxiv kev siv cov ntaub ntawv ntau li ntau tau. Feem ntau, untwisted roving ntawm cov iav fiber ntau strands yog qis dua li cov ntaub fiber ntau dua; Tus nqi ntawm kev xav tau qis dua li ntawm daim ntaub, thiab qhov tsis raug mob yog qhov zoo. , tab sis lub zog yog tsawg; Cov alkali fiber yog pheej yig dua li cov alkali-dawb fiber ntau, tab sis raws li cov alkali tsis kam, corrosion tsis kam, thiab hluav taws xob yuav poob.
