FRP pwm feem ntau yog tsim los ntawm Fiberglass Reinforced Plastic (tseem hu ua FRP). FRP yog cov khoom siv sib xyaw ua ke ntawm cov iav fibers thiab cob, uas muaj cov yam ntxwv ntawm nws cov khoom zoo heev thiab kev tiv thaiv corrosion. Cov hauv qab no muab cov ncauj lus kom ntxaws txog cov khoom siv hauv FRP pwm:
Iav Fibers: Ib qho tseem ceeb ntawm FRP pwm yog iav fiber. Cov iav fiber ntau yog lub siab - lub zog, lub teeb yuag khoom uas muaj lub zog tensile tshwj xeeb. Hauv kev tsim pwm, nws ua haujlwm los txhawb cov qauv, yog li txhim kho nws lub zog thiab rigidity.
Resin: Cov resins siv nyob rau hauv FRP pwm yog feem ntau epoxy resins los yog unsaturated polyester resins. Thaum lub sij hawm curing txheej txheem, cov resins tau txais tshuaj lom neeg cov tshuaj tiv thaiv nrog cov iav fibers los tsim ib tug robust composite qauv.
Corrosion Resistance: Vim lawv cov kev tiv thaiv zoo heev rau corrosion, FRP pwm yog dav siv nyob rau hauv ib puag ncig tshwj xeeb. Lawv muaj peev xwm tiv taus cov tshuaj tiv thaiv corrosion, yog li ua rau cov pwm los tswj lawv cov qauv kev ruaj ntseg nyob rau lub sij hawm ntev ntawm kev siv.
Lub teeb yuag: FRP yog qhov hnyav; yog li ntawd, cov pwm tsim los ntawm cov khoom siv no kuj yog lub teeb thiab yooj yim los lis thiab siv.
Hnav Resistance: FRP pwm feem ntau pom muaj kev tiv thaiv zoo rau hnav, cia lawv tiv taus qee qhov kev puas tsuaj yam tsis muaj kev cuam tshuam rau lawv qhov kev ua tau zoo.
