Cov yas ua los ntawm cov iav fiber ntau yog cov khoom sib xyaw ua ke uas muaj ntau yam sib txawv, ntau yam khoom sib txawv, thiab ntau yam kev siv. Nws yog cov khoom siv tshiab ua los ntawm cov khoom siv hluavtaws thiab cov iav fiber los ntawm cov txheej txheem sib xyaw.

Cov yam ntxwv ntawm cov iav fiber reinforced yas:

(1) Kev tiv thaiv xeb zoo: FRP yog cov khoom siv tiv thaiv xeb zoo. Nws muaj kev tiv thaiv zoo rau huab cua, dej, kua qaub thiab alkali ntawm kev sib xyaw dav dav, ntsev, thiab ntau yam roj thiab cov kuab tshuaj. Nws tau siv dav hauv kev tiv thaiv xeb tshuaj lom neeg. Txhua yam ntawm. Nws hloov cov hlau carbon; hlau tsis xeb; ntoo; cov hlau tsis yog ferrous thiab lwm yam khoom siv.

(2) Lub teeb yuag thiab muaj zog siab: Qhov ceev ntawm FRP yog nruab nrab ntawm 1.5 thiab 2.0, tsuas yog 1/4 txog 1/5 ntawm cov hlau carbon, tab sis lub zog tensile yog ze rau lossis ntau dua li cov hlau carbon, thiab lub zog sib piv rau cov hlau alloy siab. , Siv dav hauv aerospace; cov hlab ntsha siab thiab lwm yam khoom uas xav tau txo lawv qhov hnyav.

(3) Kev ua haujlwm hluav taws xob zoo: FRP yog cov khoom siv rwb thaiv tsev zoo heev, siv los ua cov insulators, thiab nws tseem tuaj yeem tswj tau zoo nyob rau hauv qhov zaus siab.

(4) Kev ua haujlwm zoo thermal: FRP muaj qhov conductivity qis, 1.25 ~ 1.67KJ ntawm chav tsev kub, tsuas yog 1/100 ~ 1/1000 ntawm cov hlau yog cov khoom siv rwb thaiv tsev zoo heev. Nws yog cov khoom siv tiv thaiv thermal zoo tshaj plaws thiab tiv taus ablation hauv cov xwm txheej ntawm kev kub ceev tam sim ntawd.

(5) Kev ua tau zoo heev: Cov txheej txheem molding tuaj yeem xaiv tau raws li cov duab ntawm cov khoom thiab cov txheej txheem yooj yim thiab tuaj yeem ua pwm ib zaug.

(6) Kev tsim qauv zoo: cov ntaub ntawv tuaj yeem xaiv tau raws li qhov yuav tsum tau ua kom tau raws li kev ua tau zoo ntawm cov khoom thiab cov qauv tsim.

(7) Cov qauv qis ntawm elasticity: Cov qauv ntawm elasticity ntawm FRP yog 2 npaug loj dua li ntoo tab sis tsuas yog 10 npaug me dua li hlau. Yog li ntawd, cov qauv khoom feem ntau xav tias tsis muaj zog txaus thiab yooj yim rau deform. Cov tshuaj tuaj yeem ua rau hauv cov qauv plhaub nyias; cov qauv sandwich kuj tseem tuaj yeem them los ntawm cov fibers siab modulus lossis cov tav txhawb nqa.

(8) Kev tiv thaiv kub tsis zoo mus sij hawm ntev: Feem ntau, FRP siv tsis tau ntev ntawm qhov kub siab, thiab lub zog ntawm cov khoom siv dav dav polyester resin FRP yuav raug txo qis ntau dua 50 degrees.

(9) Kev laus zuj zus: Nyob rau hauv qhov kev ua ntawm ultraviolet rays, cua, xuab zeb, nag thiab daus, tshuaj lom neeg, thiab kev ntxhov siab ntawm lub tshuab, nws yooj yim ua rau kev ua haujlwm poob qis.

(10) Lub zog interlaminar shear qis: Lub zog interlaminar shear yog ris los ntawm cov resin, yog li nws qis. Qhov kev sib txuas ntawm cov txheej txheem tuaj yeem txhim kho los ntawm kev xaiv cov txheej txheem, siv cov neeg sawv cev sib txuas thiab lwm txoj hauv kev, thiab sim kom tsis txhob txiav ntawm cov txheej thaum lub sijhawm tsim khoom.
