FRP, fiber ntau cov yas sib xyaw ua ke, yog ib qho chaw siv feem ntau siv rau sab nraum zoov fiber ntau optic cables; Niaj hnub no, cov cables tau siv ntau thiab ntau dua, thiab cov cables siv FRP los ua qhov chaw txhawb nqa ntxiv rau kev siv KFRP ua qhov chaw txhawb nqa.
FRP (Glass Fiber) muaj cov khoom nram qab no:
(1) Lub teeb nyhav thiab lub zog siab
Cov txheeb ze ntom ntom yog nyob nruab nrab ntawm 1.5 ~ 2.0, tsuas yog 1/4 ~ 1/5 ntawm cov pa roj carbon steel, tab sis lub zog tensile nyob ze, los yog ntau tshaj li carbon steel, thiab lub zog tshwj xeeb tuaj yeem muab piv nrog qib siab alloy hlau. Yog li ntawd, nws muaj txiaj ntsig zoo hauv aviation, foob pob hluav taws, lub dav hlau, cov hlab ntsha siab, thiab lwm yam kev siv uas yuav tsum tau txo qhov hnyav. Lub tensile, flexural thiab compressive zog ntawm qee cov epoxy FRPs tuaj yeem ncav cuag ntau dua 400Mpa.
(2) Zoo corrosion kuj:
FRP yog cov khoom siv zoo corrosion-resistant, thiab muaj kev tiv thaiv zoo rau huab cua, dej thiab cov ntsiab lus ntawm cov kua qaub, alkalis, ntsev, thiab ntau yam roj thiab cov kuab tshuaj. Nws tau raug siv rau txhua yam ntawm cov tshuaj tiv thaiv corrosion, thiab hloov carbon steel, stainless hlau, ntoo, non-ferrous hlau, thiab lwm yam.
(3) Cov khoom siv hluav taws xob zoo
Nws yog ib qho zoo heev insulating khoom siv los ua insulators. Nws tseem tuaj yeem tiv thaiv cov khoom zoo dielectric ntawm cov zaus siab. Microwave transmittance yog qhov zoo, thiab nws tau siv dav hauv radomes thiab lwm yam.
KFRP yog ib hom tshiab ntawm kev ua haujlwm siab uas tsis yog xim hlau fiber ntau optic cable reinforcing core, uas yog siv dav hauv kev nkag mus rau hauv tes hauj lwm.
KFRP muaj cov khoom nram qab no:
(1) Lub teeb nyhav thiab lub zog siab
Nws lub zog tshwj xeeb thiab qhov tshwj xeeb modulus nyob deb tshaj li ntawm cov hlau xaim thiab iav fiber reinforced fiber reinforced fiber reinforcing core;
(2) Tsawg expansion
Nyob rau hauv ntau qhov kub thiab txias, linear expansion coefficient ntawm aramid fiber reinforced fiber reinforced cable reinforcing core yog me dua li ntawm cov hlau hlau thiab iav fiber reinforced optical cable reinforcing core;
(3) Kev cuam tshuam tsis kam thiab tawg tsis kam
Lub aramid fiber reinforced fiber reinforced fiber reinforcing core tsis tsuas yog muaj lub zog tensile ultra-siab (≥ 1700MPa), tab sis kuj muaj kev cuam tshuam thiab tawg tsis kam, thiab tuaj yeem tuav lub zog tensile txog li 1300MPa txawm tias tawg;
(4) Zoo elasticity
Lub hauv paus tseem ceeb ntawm aramid fiber reinforced optical cable yog lub teeb thiab yooj yim rau khoov, thiab nws txoj kab uas hla tsawg kawg yog 24 npaug ntawm txoj kab uas hla. Sab hauv kho qhov muag cable muaj cov qauv compact, zoo nkauj tsos, zoo heev dabtsi yog khoov kev ua tau zoo, thiab yog tshwj xeeb tshaj yog haum rau xaim nyob rau hauv complex nyob rau hauv ib puag ncig.
