Kev tshuaj xyuas thiab kev siv ntawm FRP winding txheej txheem

Fiber winding yog ib qho ntawm cov txheej txheem tsim khoom ntawm resin matrix composites.Muaj peb yam tseem ceeb ntawm winding: toroidal winding, dav hlau winding thiab kauv winding.Peb txoj kev muaj lawv tus kheej cov yam ntxwv, thiab cov txheej txheem ntub dej yog siv dav tshaj plaws vim nws cov khoom siv yooj yim thiab cov nqi tsim khoom tsawg.

Nyob rau hauv cov xwm txheej ntawm kev tswj nro thiab predetermined kab zoo, cov nruam fiber ntau los yog daim ntaub impregnated nrog resin kua nplaum yog mob tsis tu ncua, tusyees thiab tsis tu ncua ntawm cov tub ntxhais pwm los yog hauv ob sab phlu los ntawm kev siv tshwj xeeb winding khoom, thiab ces solidified nyob rau hauv ib tug tej yam kub thiab txias ib puag ncig los ua ib tug Composite khoom molding txoj kev ntawm tej yam khoom zoo li.Kev ua daim duab ntawm fiber ntau winding molding txheej txheem:

Muaj peb yam tseem ceeb ntawm winding (Daim duab 1-2): toroidal winding, planar winding thiab kauv winding.Nplhaib rau cov khoom siv ntxiv ntawm cov pwm thiab cov tub ntxhais axis ntawm ze li ntawm 90 degrees (feem ntau yog 85-89) nyob rau hauv cov kev taw qhia ntawm kev nruam winding ntawm mandrel, ntxiv cov ntaub ntawv nrog cov tub ntxhais ntawm matrix ntawm ob qho tag nrho ntawm tus ncej qhov tangent thiab nruam. winding nyob rau hauv cov kev taw qhia ntawm lub dav hlau nyob rau hauv lub mandrel, muab kauv lub qhov txhab reinforced cov ntaub ntawv thiab nrog tangent ntawm ob kawg ntawm lub mandrel, tab sis nyob rau hauv ib tug kauv mandrel nruam winding ntawm mandrel.

Txoj kev loj hlob ntawm fiber ntau winding tshuab yog ze ze rau kev txhim kho cov ntaub ntawv txhawb zog, resin systems thiab thev naus laus zis inventions.Txawm hais tias nyob rau hauv Han Dynasty, cov txheej txheem ntawm kev ua riam phom xws li Gorilli thiab halberd tuaj yeem ua los ntawm impregnating lacquer nrog ntev ntoo ncej ntxiv rau longitudinal xyoob thiab cov kab lo lo ntxhuav, cov txheej txheem ntawm fiber ntau winding tsis dhau los ua cov khoom siv sib xyaw ua ke kom txog rau thaum lub caij nplooj zeeg. Xyoo 1950s.Nyob rau hauv 1945, thawj lub caij nplooj ntoos hlav-dawb log ncua kev kawm ntawv tau ntse tsim los ntawm fiber ntau winding tshuab, thiab nyob rau hauv 1947, thawj fiber winding tshuab tau tsim.Nrog txoj kev loj hlob ntawm kev ua tau zoo fibers xws li carbon fiber thiab aramong fiber ntau thiab cov tsos ntawm microcomputer tswj winding tshuab, fiber ntau winding txheej txheem, raws li ib tug heev mechanized composite khoom tsim technology, tau tsim sai heev, thiab tau siv nyob rau hauv yuav luag tag nrho cov teb tau. txij li xyoo 1960.

Hais txog US:hebei uaYuniu Fiberglass Manufacturing Co., Ltd.Peb tsuas yog tsim thiab muag e-hom fiberglass khoom, xws li fiberglass roving, fiberglass tws silk, fiberglass tws xav, fiberglass gingham, koob xav, fiberglass ntaub thiab hais txog.Yog tias xav tau, thov hu rau peb dawb.

Raws li qhov sib txawvua chemical thiab lub cev lub xeev of resin substrate thaum wrapping, wrapping techniques tuaj yeem muab faib ua txoj kev qhuav, ntub thiab ib nrab qhuav:

1. Qhuav

Qhuav winding txais pre-impregnated daim kab xev ntawm theem B tom qab pre-impregnated.Preimpregnated strips yog tsim thiab muab rau hauv cov nroj tsuag tshwj xeeb lossis kev cob qhia.Rau qhuav winding, lub pre-soaked yarn siv yuav tsum tau rhuab thiab softened ntawm lub tshuab winding ua ntej yuav raug mob rau lub hauv paus pwm.Qhov zoo ntawm cov xov paj prepreg tuaj yeem tswj tau qhov tseeb vim tias cov ntsiab lus ntawm cov kua nplaum, qhov loj thiab zoo ntawm daim kab xev tuaj yeem kuaj xyuas thiab tshuaj xyuas ua ntej winding.Kev ua haujlwm ntawm qhuav winding yog siab dua, qhov ceev winding tuaj yeem ncav cuag 100-200m / min, thiab qhov chaw ua haujlwm huv dua.Txawm li cas los xij, cov khoom siv winding qhuav yog qhov nyuaj thiab kim dua, thiab lub zog interlaminar shear lub zog ntawm cov khoom winding yog qis dua.

2. ntub dej

Txoj kev ntub dej ntub dej yog cua cov fiber ntau ntawm cov tub ntxhais tuag ncaj qha los ntawm kev tswj nruj tom qab lub nras thiab dip kua nplaum, thiab tom qab ntawd solidify.Cov khoom siv ntub dej ntub dej yog qhov yooj yim, tab sis vim tias txoj siv xov paj yog qhov txhab tam sim ntawd tom qab dipping, nws nyuaj rau kev tswj thiab tshuaj xyuas cov kua nplaum ntawm cov khoom thaum lub sij hawm winding.Lub caij no, qhov tsis xws luag xws li npuas thiab qhov pores yog yooj yim tsim nyob rau hauv cov khoom thaum cov kuab tshuaj nyob rau hauv cov kua nplaum yog solidified, thiab lub nro kuj yog ib qho nyuaj rau tswj thaum lub winding.Nyob rau tib lub sijhawm, cov neeg ua haujlwm ua haujlwm nyob rau hauv cov kuab tshuaj volatile cua thiab ib puag ncig ntawm ya fiber ntau cov plaub hau luv luv, kev ua haujlwm tsis zoo.

3. Semi-qhuav txoj kev

Piv nrog rau cov txheej txheem ntub dej, cov txheej txheem ib nrab qhuav ntxiv cov cuab yeej ziab ntawm txoj kev los ntawm fiber ntau dipping mus rau winding rau cov tub ntxhais pwm, thiab pib tshem tawm cov kuab tshuaj hauv cov kua nplaum ntawm cov xov paj.Nyob rau hauv sib piv rau cov txheej txheem qhuav, cov txheej txheem semi-qhuav tsis cia siab rau cov txheej txheem txheej txheem preimpregnation.Txawm hais tias cov kua nplaum cov ntsiab lus ntawm cov khoom tsis yooj yim rau kev tswj xyuas kom raug raws li cov txheej txheem ntub dej thiab ntau tshaj li cov txheej txheem ntawm cov khoom siv ziab qhuav qhuav dua li cov txheej txheem ntub dej, kev siv zog ntawm cov neeg ua haujlwm yog ntau dua, tab sis cov npuas, porosity thiab lwm yam tsis xws luag hauv cov khoom siv. cov khoom raug txo qis heev.

Peb txoj kev muaj lawv tus kheej cov yam ntxwv, thiab cov txheej txheem ntub dej yog siv dav tshaj plaws vim nws cov khoom siv yooj yim thiab cov nqi tsim khoom tsawg.Qhov zoo thiab qhov tsis zoo ntawm peb txoj kev winding yog muab piv rau hauv Table 1-1.

Table 1-1 Qhov piv ntawm kaum txhiab txoj kev ntawm peb txoj kev winding
