Nyob rau hnub dhau los, cov xov hluav taws xob sab nraum zoov feem ntau siv FRP ua lub hauv paus txhawb nqa. Niaj hnub no, muaj qee cov xov hlau tsis yog siv FRP ua lub hauv paus txhawb nqa xwb, tab sis kuj siv KFRP ua lub hauv paus txhawb nqa.
FRP muaj cov yam ntxwv hauv qab no:
(1) Lub teeb thiab muaj zog
Qhov ceev sib piv yog ntawm 1.5 ~ 2.0, uas txhais tau tias 1/4 ~ 1/5 ntawm cov hlau carbon, tab sis lub zog tensile yog ze rau lossis siab dua li ntawm cov hlau carbon, thiab lub zog tshwj xeeb tuaj yeem piv nrog cov hlau alloy qib siab. Lub zog tensile, flexural thiab compressive ntawm qee cov epoxy FRP tuaj yeem ncav cuag ntau dua 400Mpa.
(2) Kev tiv thaiv xeb zoo
FRP yog cov khoom siv tiv taus corrosion zoo, thiab muaj kev tiv taus huab cua, dej thiab cov kua qaub, alkali, ntsev, thiab ntau yam roj thiab cov kuab tshuaj.
(3) Cov khoom siv hluav taws xob zoo
FRP yog ib yam khoom siv rwb thaiv tsev zoo heev, siv los ua cov insulators. Nws tseem tuaj yeem tiv thaiv cov khoom dielectric zoo hauv qab zaus siab. Nws muaj qhov nkag tau zoo ntawm microwave.
KFRP (polyester aramid xov)
Aramid fiber reinforced fiber optic cable reinforcement core (KFRP) yog ib hom tshiab ntawm kev ua haujlwm siab tsis yog hlau fiber optic cable reinforcement core, uas yog siv dav hauv kev nkag mus rau hauv tes hauj lwm.
(1) Lub teeb thiab muaj zog
Cov tub ntxhais fiber optic cable uas muaj aramid fiber reinforced muaj qhov ceev tsawg thiab muaj zog siab, thiab nws lub zog tshwj xeeb thiab modulus tshwj xeeb ntau dua li cov hlau hlau thiab iav fiber reinforced optical cable cores.
(2) Kev nthuav dav tsawg
Cov aramid fiber reinforced optical cable reinforced core muaj cov coefficient nthuav dav qis dua li cov hlau hlau thiab cov iav fiber reinforced optical cable reinforced core hauv qhov kub ntau.
(3) Kev cuam tshuam tsis kam thiab kev tawg tsis kam
Cov aramid fiber reinforced fiber optic cable reinforced core tsis yog tsuas yog muaj lub zog tensile siab heev (≥1700MPa), tab sis kuj tseem muaj kev cuam tshuam thiab kev tawg, thiab tuaj yeem tswj tau lub zog tensile ntawm txog 1300MPa txawm tias thaum tawg.
(4) Kev ywj pheej zoo
Cov fiber aramid fiber reinforced fiber optic cable reinforced core 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. Cov cable sab hauv tsev muaj cov qauv me me, zoo nkauj thiab kev ua tau zoo heev khoov, uas yog tshwj xeeb tshaj yog rau kev txuas hluav taws xob hauv cov chaw sab hauv tsev nyuaj.
