FRP ndi KFRP——Zowonjezera pakati pa chingwe chachikopa

FRP, pulasitiki yopangidwa ndi ulusi wolimbikitsidwa, ndi chinthu chogwiritsidwa ntchito kwambiri pakati pa zingwe zakunja za fiber optic; Masiku ano, zingwe zimagwiritsidwa ntchito kwambiri, ndipo zingwe zimagwiritsa ntchito FRP ngati zolimbitsa pakati kuwonjezera pa kugwiritsa ntchito KFRP ngati zolimbitsa pakati.

FRP (Glass Fiber) ili ndi zinthu zotsatirazi:

(1) Kulemera kopepuka komanso mphamvu zambiri
Kuchulukana kwake kuli pakati pa 1.5 ~ 2.0, 1/4 ~ 1/5 yokha ya chitsulo cha kaboni, koma mphamvu yake yomangika ili pafupi, kapena kuposa chitsulo cha kaboni, ndipo mphamvu yake yeniyeniyo ingayerekezeredwe ndi chitsulo cha alloy chapamwamba. Chifukwa chake, imagwira ntchito bwino kwambiri mu ndege, maroketi, zombo zamlengalenga, zombo zothamanga kwambiri, ndi ntchito zina zomwe zimafuna kuchepetsa kulemera. Mphamvu yomangika, yopindika komanso yokakamiza ya ma epoxy FRP ena imatha kufika pa 400Mpa.

(2) Kukana dzimbiri kwabwino:
FRP ndi chinthu chabwino cholimbana ndi dzimbiri, ndipo chimalimbana bwino ndi mlengalenga, madzi ndi kuchuluka kwa ma asidi, alkali, mchere, ndi mafuta osiyanasiyana ndi zosungunulira. Chagwiritsidwa ntchito pazinthu zonse zokhudzana ndi mankhwala oletsa dzimbiri, ndipo chikulowa m'malo mwa chitsulo cha kaboni, chitsulo chosapanga dzimbiri, matabwa, zitsulo zopanda chitsulo, ndi zina zotero.

(3) Kapangidwe kabwino ka magetsi
Ndi chinthu chabwino kwambiri chotetezera kutentha chomwe chimagwiritsidwa ntchito popanga zotetezera kutentha. Chimathabe kuteteza mphamvu zabwino za dielectric pa liwiro lapamwamba. Kutumiza kwa microwave ndi kwabwino, ndipo kwagwiritsidwa ntchito kwambiri mu radomes ndi zina zotero.

KFRP ndi mtundu watsopano wa chingwe cholimbitsa chingwe cha fiber optic chomwe sichili chachitsulo chomwe chimagwira ntchito bwino kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'maukonde olumikizirana.

KFRP ili ndi zinthu zotsatirazi:

(1) Kulemera kopepuka komanso mphamvu zambiri
Mphamvu yake yeniyeni ndi modulus yake yeniyeni zimaposa kwambiri waya wachitsulo ndi ulusi wagalasi wolimbikitsidwa ndi ulusi wolimbikitsidwa ndi ulusi wolimbikitsidwa ndi ulusi;

(2) Kukulitsa kochepa
Mu kutentha kosiyanasiyana, coefficient yowonjezereka ya pakati pa chingwe cholimbitsa chingwe cha aramid ndi yaying'ono kuposa ya pakati pa waya wachitsulo ndi pakati pa chingwe cholimbitsa chingwe chagalasi;

(3) Kukana kukhudzidwa ndi kukana kusweka
Chingwe cholimbitsa chingwe cha aramid chomwe chimalimbitsa ulusi wolimbikitsidwa sichimangokhala ndi mphamvu yokoka kwambiri (≥ 1700MPa), komanso chimakhudza kukana ndi kukana kusweka, ndipo chimatha kusunga mphamvu yokoka ya pafupifupi 1300MPa ngakhale itasweka;

(4) Kusinthasintha kwabwino
Chingwe cholimbitsa cha aramid fiber cholimbitsa chingwe chowunikira ndi chopepuka komanso chosavuta kupindika, ndipo kukula kwake kocheperako kopindika ndi kuwirikiza kawiri kokha kuposa kukula kwake. Chingwe chowunikira chamkati chili ndi kapangidwe kakang'ono, mawonekedwe okongola, magwiridwe antchito abwino opindika, ndipo ndi choyenera kwambiri pakugwirizanitsa mawaya m'malo ovuta amkati.
