Tsev so linen laub - Bona linen laub (pom zoo tub lag luam) - tsev so linen laub nqi

Fiberglass reinforced yas, feem ntau hu ua FRP, uas yog fiber ntau reinforced composite yas.Nws yog cov khoom siv sib xyaw nrog cov iav fiber ntau thiab nws cov khoom (iav ntaub, siv, xav, xov paj, thiab lwm yam) raws li kev txhawb zog thiab cov khoom siv hluavtaws ua cov khoom siv matrix.Lub laub linen ua los ntawm FRP muaj qhov zoo thiab qhov tsis zoo hauv qab no:
Qhov zoo: lub teeb yuag, lub zog siab, qhov sib txheeb ze ntawm 1.5-2.0, tsuas yog 1 / 4-1 / 5 ntawm carbon steel, tab sis lub zog tensile nyob ze.Lub tensile, dabtsi yog khoov thiab compression zog ntawm ib co epoxy FRP tuaj yeem ncav cuag ntau tshaj 400MPa.
Corrosion resistant FRP yog cov khoom siv zoo corrosion-resistant, uas muaj kev tiv thaiv zoo rau huab cua, dej, cov ntsiab lus dav dav ntawm acid, alkali, ntsev, nrog rau ntau yam roj thiab cov kuab tshuaj.
Cov txheej txheem yog yooj yim, cov txheej txheem yog yooj yim, thiab tuaj yeem tsim nyob rau hauv ib lub sij hawm, kom cov khoom muaj kev ncaj ncees.
Disadvantages: tsis zoo elasticity.Lub elastic modulus ntawm FRP yog siab dua cov hlau (E = 2.1 × 105) 10 npaug me dua, yog li nws feem ntau xav tias qhov rigidity tsis txaus thiab yooj yim rau deform hauv cov khoom qauv.Tsis zoo kub tsis kam, dav dav FRP tsis tuaj yeem siv rau lub sijhawm ntev ntawm qhov kub thiab txias.Thaum lub dav hlau polyester FRP siab tshaj 50 ℃ thiab cov epoxy FRP dav tshaj 60 ℃, lub zog txo qis.Kev laus yooj yim yog qhov tsis xws luag ntawm cov yas, thiab FRP tsis muaj qhov tshwj xeeb.Nws yog ib qho yooj yim rau embrittle thiab kev puas tsuaj nyob rau hauv qhov kev txiav txim ntawm UV, tshuaj nruab nrab thiab txhua yam kev nyuaj siab.Cov residue tom qab tshem tawm ntawm ib puag ncig muaj kuab paug muaj qee qhov kev ua qias tuaj rau ib puag ncig.
