Dab tsi yog cov ntaub ntawv sib txhuam ntawm cov pawm nres
Daim ntawv thov ntawm cov ntaub ntawv sib txhuam hauv cov khoom siv nres yog ib qho tseem ceeb, cov tuam txhab lag luam hauv qab no Huaruifeng yuav qhia koj txog cov ntaub ntawv sib txhuam ntawm cov ntaub ntawv, Kuv ntseeg tias tom qab nyeem tsab xov xwm no peb muaj kev nkag siab zoo ntawm cov ntaub ntawv sib txhuam.
Cov khoom siv sib txhuam yog cov khoom siv polymer ternary composite, uas suav nrog peb qhov chaw: polymer compound li binder; Nrog inorganic los yog organic fiber ua lub zog tivthaiv; Cov muab tub lim yog siv los ua kev sib txhuam cov cuab yeej tswj hwm lossis cov khoom sib xyaw.
1.Organic binder
Cov organic binders siv rau kev sib txhuam cov ntaub ntawv yog phenolic resin thiab hluavtaws roj hmab, thiab phenolic resin yog lub ntsiab. Lawv cov yam ntxwv thiab kev ua haujlwm yog tias thaum nyob rau ntawm qee qhov cua sov, nws ua ntej softening thiab tom qab ntawd nkag mus rau hauv lub xeev khov, ua rau cov dej ntws thiab cov khoom sib xws hauv cov khoom siv los tsim cov matrix ntawm cov khoom, thiab thaum kawg los ntawm cov roj hmab vulcanization ntawm resin curing. , fiber ntau thiab muab tub lim ua ke los ua ib qho kev ntxhib los mos nrog lub zog loj thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov ntaub ntawv sib txhuam. Cov kev xav tau zoo rau resin yog:
(1) Kev ua haujlwm kub zoo, zoo thermal decomposition kub thiab qis thermal poob.
(2) Lub fineness ntawm cov hmoov resin yog siab, uas yog conducive mus rau lub uniformity ntawm sib tov dispersion thiab yuav txo tau tus nqi ntawm resin nyob rau hauv cov mis.
(3) Dawb hmoov cov ntsiab lus yog tsawg.
(4) Tsim nyog curing ceev thiab khiav nrug.
2. Fiber reinforced khoom
Cov khoom siv fiber ntau yog cov khoom siv ntawm cov khoom sib txhuam, uas muab cov khoom sib txhuam kom txaus lub zog los tiv thaiv lub zog ntawm kev sib tsoo thiab riveting ua cov ntawv sib txhuam hauv cov txheej txheem ntau lawm, nrog rau kev cuam tshuam quab yuam, shear quab yuam. thiab siab generated los ntawm lub braking thiab kis tau tus mob thaum lub sij hawm siv cov kev sib txhuam daim ntawv. Raws li cov kev ua haujlwm tiag tiag ntawm kev sib txhuam phaj, cov khoom siv lub zog sib xws ntawm cov phaj sib txhuam yog muab tso rau pem hauv ntej los ntawm cov qauv tsim thiab cov tuam txhab tsheb hauv Suav teb. Xws li: cuam tshuam lub zog, khoov lub zog, compressive zog, shear lub zog, thiab lwm yam. Yuav kom ua tau raws li cov kev xav tau ntawm kev ua tau zoo, nws yog ib qho tsim nyog yuav tau xaiv cov fiber ntau tsim nyog kom ua tau raws li cov khoom muaj zog.
Kev sib txhuam cov ntaub ntawv rau nws siv cov khoom siv fiber ntau
(1) Cov nyhuv txhim kho yog qhov zoo.
(2) Ua haujlwm kub zoo. Tsis muaj kev sib txhuam, carbonization thiab thermal decomposition ntawm kev sib txhuam ua haujlwm kub.
(3) Nws muaj qhov sib txhuam coefficient.
(4) Lub hardness yuav tsum tsis txhob siab dhau kom tsis txhob nres lub suab nrov thiab kev puas tsuaj rau lub brake disc lossis nruas.
(5) Cov txheej txheem ua haujlwm tau zoo.
3.filler
Cov muab tub lim nyob rau hauv cov khoom siv kev sib txhuam yog tsim los ntawm kev sib txhuam cov cuab yeej regulator thiab ib tug compounding neeg sawv cev. Lub hom phiaj ntawm kev siv fillers feem ntau yog nyob rau hauv cov nram qab no yam
(1) Kho thiab txhim kho cov khoom sib txhuam, cov khoom siv lub cev thiab lub zog ntawm cov khoom siv
(2) Tswj cov khoom thermal expansion coefficient, thermal conductivity, shrinkage tus nqi, nce stability ntawm cov khoom loj
(3) Txhim kho braking nrov ntawm cov khoom
(4) Txhim kho cov txheej txheem tsim khoom thiab kev ua haujlwm ntawm cov khoom.
(5) Txhim kho cov khoom zoo li zoo thiab ntom
(6) Txo cov nqi tsim khoom
