FRP Vaj Huam Sib Luag
Kev piav qhia txog khoom
FRP (tseem hu ua iav fiber reinforced yas, luv luv li GFRP lossis FRP) yog cov khoom siv ua haujlwm tshiab ua los ntawm cov khoom siv hluavtaws thiab iav fiber los ntawm cov txheej txheem sib xyaw.
Daim ntawv FRP yog cov khoom siv thermosetting polymer nrog cov yam ntxwv hauv qab no:
(1) lub teeb yuag thiab lub zog siab.
(2) Kev tiv thaiv corrosion zoo FRP yog cov khoom siv tiv thaiv corrosion zoo.
(3) Cov khoom siv hluav taws xob zoo yog cov ntaub ntawv rwb thaiv tsev zoo heev, siv los tsim cov insulators.
(4) Cov khoom siv thermal zoo FRP muaj cov thermal conductivity tsawg.
(5) Tsim tau zoo
(6) Kev ua tau zoo heev
Cov ntawv thov:
