Dab tsi yog qhov txawv ntawm tws strand lev thiab woven roving?

Qhov sib txawv tseem ceeb ntawmchopped strand lev (CSM) thiabWoven roving (WR) nyob rau hauv lawv cov qauv, lub zog, thiab kev siv hauv fiberglass-reinforced composites. Nov yog qhov kev sib piv ntxaws:

          

1. Qauv & Kev tsim khoom

Chopped Strand Mat (CSM)	Woven Roving (WR)
Ua los ntawm randomly orientedluv iav fibers(feem ntau 1-3 ntiv tes ntev) sib txuas nrog cov khoom siv-soluble binder (hmoov lossis emulsion).	Ua los ntawmnruam iav fiberswoven rau hauv ib qho hnyav, ntxhib ntaub (zoo li lub hnab burlap).
Tsis-woven, isotropic (sib npaug zog nyob rau hauv tag nrho cov lus qhia).	Woven, anisotropic (muaj zog nyob rau hauv cov kev taw qhia ntawm cov fibers, feem ntau 0 ° thiab 90 °).
Tsawg fiber ntau ntom, fluffy thiab yooj yim txiav / zoo li.	Siab dua kev ceev, txhav thiab nyuaj rau drape hla cov duab nyuaj.

 

2.Mechanical Properties

CSM	WR
Tsawg zogtab sis muabuniform reinforcementnyob rau hauv tag nrho cov lus qhia.	Siab zog tensile(tshwj xeeb tshaj yog nyob rau hauv weave kev taw qhia) tab sis tsis muaj zog ntawm cov ces kaum.
Zoo raunruj thiab cuam tshuam tsis kamtab sis tsis yog rau high-load applications.	Siv qhov twgsiab zog-rau-qhov hnyav pivxav tau (piv txwv li, nkoj hulls, tanks).
Feem ntau siv hauvtxheej nrog resinrau cov hom phiaj dav dav laminates.	Feem ntauua ke nrog CSMnyob rau hauv hybrid laminates kom zoo interlaminar bonding.

3. Resin Absorption & Layup

CSM	WR
Soaks ntau resin(siab dua resin-rau-fiber piv, ~ 2: 1 los ntawm qhov hnyav).	Siv tsawg resin(ntau fiber ntau ntom, ~ 1: 1 resin-rau-fiber ratio).
Yooj yim rau ntub tawm (zoo rau tes layup).	Ua kom ntub dej tawm (tej zaum yuav xav tau cov chais / txhuam kom tshem tawm cov hnab ntim cua).
Feem ntau siv raws li ib tugthawj txheejkom zoo adhesion rau pwm.	Siv hauvcov txheej txheem txheej txheemrau ntxiv dag zog.

 

4. Kev siv ntau

Chopped Strand Mat (CSM)	Woven Roving (WR)
✔ Lub hom phiaj dav dav fiberglass qhov chaw (piv txwv li, chav da dej, vaj huam sib luag). ✔ Kho kev ua haujlwm (yooj yim ua raws li nkhaus). ✔ Siv nrog polyester cob (binder dissolves).	✔ Cov qauv muaj zog (nkoj hulls, cua turbine hniav). ✔ Automotive qhov chaw (tsheb lub cev, trailer). ✔ Tank thiab kav dej yuav tsum tau muaj zog taw qhia.

5.Cov neeg muab khoom thoob ntiaj teb

Owens Corning(USA)

Ib qho ntawm cov tuam txhab loj tshaj plaws ntawm fiberglass thiab cov ntaub ntawv sib xyaw, muab kev ua haujlwm siab CSM rau kev lag luam marine, tsheb, thiab kev tsim kho.

Jushi Group(Tuam Tshoj)

Ib lub ntiaj teb fiberglass cov neeg tsim khoom loj tshaj plaws, muab cov txiaj ntsig zoo CSMthiab WRrau kev lag luam thoob ntiaj teb.

Saint-Gobain Vetrotex(Fabkis)

Lub ntiaj teb no tus thawj coj hauv iav fiber reinforcements, muab premium tws strand levthiab woven roving.

Ruifiber (Tuam Tshoj)

Paub txog cov khoom siv fiberglass zoo, suav nrog CSM thiab WR rau kev tsim kho thiab kev lag luam.

 

6. Nqi & Kev Them Nqi

CSMyogpheej yig duathiab yooj yim los tuav tab sis yuav tsum tau ntau resin.

WRyogmuaj zog thiab sib zogtab sis nyuaj ua hauj lwm nrog rau cov duab complex.

Hybrid Use Case (CSM + WR)

Muaj ntau yam sib xyaw ua ke ob qho tib si:

Thawj txheej: CSM rau pwm adhesion thiab du tiav.

Nruab nrab txheej: WR rau lub zog.

Txheej kawg: CSM rau qhov chaw huv.
