FRP, cov yas sib xyaw ua los ntawm fiber ntau, yog ib qho khoom siv txhawb nqa rau cov xov hlau fiber optic sab nraum zoov; Niaj hnub no, cov cables tau siv ntau dua thiab ntau dua, thiab cov cables siv FRP ua cov khoom txhawb nqa hauv nruab nrab ntxiv rau kev siv KFRP ua cov khoom txhawb nqa hauv nruab nrab.
FRP (Iav Fiber) muaj cov yam ntxwv hauv qab no:
(1) Lub teeb yuag thiab lub zog siab
Qhov ceev ntawm cov hlau carbon yog nruab nrab ntawm 1.5 ~ 2.0, tsuas yog 1/4 ~ 1/5 ntawm cov hlau carbon, tab sis lub zog tensile yog ze rau, lossis ntau dua li cov hlau carbon, thiab lub zog tshwj xeeb tuaj yeem piv nrog cov hlau alloy qib siab. Yog li ntawd, nws muaj txiaj ntsig zoo hauv kev tsav dav hlau, foob pob hluav taws, chaw dav hlau, cov hlab ntsha siab, thiab lwm yam kev siv uas xav tau kev txo qhov hnyav. Lub zog tensile, flexural thiab compressive ntawm qee cov epoxy FRPs tuaj yeem ncav cuag ntau dua 400Mpa.
(2) Kev tiv thaiv xeb zoo:
FRP yog ib yam khoom siv uas tiv taus xeb zoo, thiab nws tiv taus huab cua, dej thiab feem ntau cov kua qaub, alkali, ntsev, thiab ntau yam roj thiab cov kuab tshuaj. Nws tau siv rau txhua yam ntawm kev tiv thaiv xeb tshuaj, thiab hloov cov hlau carbon, hlau tsis xeb, ntoo, cov hlau tsis yog ferrous, thiab lwm yam.
(3) Cov khoom siv hluav taws xob zoo
Nws yog ib yam khoom siv rwb thaiv tsev zoo heev uas siv los ua cov insulators. Nws tseem tuaj yeem tiv thaiv cov khoom dielectric zoo ntawm cov zaus siab. Kev xa hluav taws xob microwave zoo, thiab nws tau siv dav hauv radomes thiab lwm yam.
KFRP yog ib hom tshiab ntawm cov xov hlau fiber optic uas ua haujlwm tau zoo uas tsis yog hlau, uas siv dav hauv cov tes hauj lwm nkag mus.
KFRP muaj cov yam ntxwv hauv qab no:
(1) Lub teeb yuag thiab lub zog siab
Nws lub zog tshwj xeeb thiab modulus tshwj xeeb tshaj li ntawm cov hlau hlau thiab cov iav fiber reinforced fiber reinforced fiber cable reinforcing core;
(2) Kev nthuav dav tsawg
Hauv ntau qhov kub thiab txias, qhov coefficient ntawm linear expansion ntawm aramid fiber reinforced fiber reinforced cable reinforcing core me dua li ntawm cov hlau hlau thiab iav fiber reinforced optical cable reinforcing core;
(3) Kev cuam tshuam tsis kam thiab kev tawg tsis kam
Cov fiber aramid fiber reinforced fiber cable reinforcing core tsis yog tsuas yog muaj lub zog tensile siab heev (≥ 1700MPa), tab sis kuj tseem muaj kev cuam tshuam thiab kev tawg tsis kam, thiab tuaj yeem tswj tau lub zog tensile ntawm txog 1300MPa txawm tias muaj kev tawg;
(4) Kev ywj pheej zoo
Lub hauv paus ntawm aramid fiber reinforced optical cable yog lub teeb thiab yooj yim rau khoov, thiab nws qhov tsawg kawg nkaus khoov txoj kab uas hla tsuas yog 24 npaug ntawm txoj kab uas hla. Lub sab hauv tsev optical cable muaj cov qauv me me, zoo nkauj tsos, kev ua tau zoo heev khoov, thiab tshwj xeeb tshaj yog tsim rau kev txuas hluav taws xob hauv cov chaw sab hauv tsev nyuaj.
