Cov khoom siv fiber ntau sib txhuam disc - carbon fiber txhuam disc
Cia kuv qhia koj txog hom tshiab ntawm cov khoom siv fiber ntau txhuam phaj, uas yog carbon fiber txhuam phaj. Nws yog cov khoom siv fiber ntau sib txhuam phaj tsim los ntawm cua sov cov organic fiber lossis cov khoom siv roj molecular hydrocarbon tsawg rau 1500 degree, nrog cov ntsiab lus carbon ntau dua 90%. Vim tias cov pa roj carbon fiber ntau muaj qhov zoo ntawm cov ntaub ntawv carbon, nws kuj muaj hluav taws xob thiab thermal conductivity ntawm hlau txhuam daim hlau, lub tshav kub tsis kam thiab corrosion kuj ntawm cov ntaub ntawv ceramic, softness thiab knitability ntawm textile fibers, thiab lub teeb yuag thiab yooj yim ua cov khoom. ntawm cov ntaub ntawv polymer. , yog cov khoom siv ntau yam thiab ntau lub hom phiaj ua haujlwm thiab cov khoom siv. Yog li ntawd, nws yog dav siv nyob rau hauv aerospace, aviation, tub rog kev lag luam, tsheb, kev kho mob, tshuaj lom neeg kev lag luam, kab lis kev cai thiab kev ua si nawv khoom thiab lwm yam teb.
Raws li kev faib tawm ntawm cov khoom siv raw, cov roj carbon fiber ntau tuaj yeem muab faib ua polyacrylonitrile-raws li cov pa roj carbon fiber ntau sib txhuam, cov pa roj carbon fiber ntau sib txhuam, cov nplaum-raws li carbon fiber txhuam thiab phenolic resin carbon fiber sib txhuam pads. Tam sim no, nws feem ntau yog polyacrylonitrile-raws li carbon fiber txhuam phaj thiab pitch-raws li carbon fiber txhuam phaj, thiab muaj ob peb lwm carbon fibers. Pitch-raws li carbon fiber txhuam daim hlau yog muab faib ua ob hom: dav dav-lub hom phiaj pitch-based carbon fiber thiab high-performance pitch-based carbon fiber.
Cov pa roj carbon fiber muaj cov khoom zoo hauv qab no: Lub teeb tshwj xeeb lub ntiajteb txawj nqus; Siab tshwj xeeb modulus; Cov khoom zoo ntawm lub cev thiab txhua yam xws li hnav tsis kam, qaug zog ua haujlwm, txo kev vibration thiab lub zog nqus; Resistant rau cov kua qaub, alkali thiab ntsev corrosion, thiab tuaj yeem tsim cov ntxeem tau thiab ua kom muaj zog ntawm cov pa roj carbon fiber ntau; Thermal expansion coefficient Me me, zoo thermal conductivity; kev ua haujlwm tsis poob qis hauv qhov kub thiab txias; muaj lubricity thiab tsis ntub hauv cov hlau molten, uas tuaj yeem txo tus nqi hnav; Cov yam ntxwv zoo li no qhia tau hais tias muaj kev loj hlob zoo thiab kev cia siab rau hauv kev ua haujlwm ntawm cov ntaub ntawv sib txhuam, carbon fiber Kev siv cov ntaub ntawv sib txhuam tau zoo tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov ntaub ntawv sib txhuam thiab cov ntawv sib txhuam. Nws yog feem ntau ntxiv rau resin, hlau los yog ceramics, carbon, cement thiab lwm yam matrices los ua carbon fiber reinforced composite kev sib txhuam daim hlau. Nws yog ib qho khoom siv zoo heev rau kev sib txhuam. ib daim.
