Xav paub ntau ntxiv txog Composites (1) Txoj kev tsim khoom
Kev tsim cov txheej txheem ntawm cov ntaub ntawv sib xyaw yog lub hauv paus thiab qhov tseem ceeb rau kev txhim kho kev lag luam sib xyaw. Nrog ntau thiab ntau thaj chaw siv cov ntaub ntawv sib xyaw, peb txoj kev lag luam tau tsim kho sai nrog cov txheej txheem ib txwm maj mam txhim kho thaum txoj kev tshiab tau tshwm sim tas li.
Cov txheej txheem tsim khoom feem ntau suav nrog ob yam hauv qab no:
1 - sib sau piv txwv li lub prepreg yog nteg rau hauv ib qho duab raws li qhov yuav tsum tau muaj ntawm cov khoom, uas feem ntau yog cov duab ntawm cov khoom;
2 - curing piv txwv li lub laminated prepreg uas tau muab tso rau hauv ib qho zoo li yog tsau nyob rau hauv lub zog ntawm yam xws li kub, lub sij hawm thiab siab, thiab muaj peev xwm ua tau raws li qhov xav tau kev ua tau zoo.
(1) Tes lay-up - ntub layup;

(17) Centrifugal casting raj;
Cov ntsiab cai ntawm kev xaiv cov txheej txheem ntau lawm:
Thaum xaiv ib txoj kev tsim khoom, nws yuav tsum ua kom tau raws li ntau yam xws li kev ua haujlwm ntawm cov khoom siv, cov khoom zoo thiab cov txiaj ntsig kev lag luam tib lub sijhawm, suav nrog:
1. Cov duab thiab qhov loj ntawm cov khoom
2. Cov khoom lag luam thiab cov kev xav tau zoo (xws li lub cev thiab cov khoom siv tshuaj lom neeg ntawm cov khoom, cov khoom muaj zog thiab nto, thiab lwm yam)
3. Ntau lawm batch loj thiab lub sij hawm txhuas (tso cai rau ntau lawm voj voog)
4. Cov khoom siv thiab cov nyiaj txiag uas lub tuam txhab muab tau
5. Muaj txiaj ntsig kev lag luam
