FRP (Fiber Reinforced Polymer)

Kev Taw Qhia Ntawm FRP 3D Printing

Fiber Reinforced Polymer (FRP) yog cov khoom siv sib xyaw uas muaj cov polymer matrix reinforced nrog fibers. Cov khoom siv ntau yam no sib xyaw ua ke lub zog thiab nruj ntawm fibers-xws li iav, carbon, los yog aramid fibers-nrog lub teeb yuag thiab corrosion-resistant zog ntawm polymer resins xws li epoxy los yog polyester. FRP pom cov ntawv thov dav dav thoob plaws ntau qhov kev lag luam vim nws cov khoom siv tshwj xeeb, suav nrog lub zog-rau-qhov hnyav piv, ua haujlwm ntev, thiab tsim qauv yooj yim. Cov kev siv feem ntau suav nrog kev txhim kho cov qauv hauv cov tsev, kho cov choj, cov khoom siv dav hlau, cov khoom siv tsheb, kev tsim kho hauv hiav txwv, thiab cov khoom siv kis las. Lub peev xwm los txiav txim siab FRP composites rau cov kev ua haujlwm tshwj xeeb ua rau lawv nyiam kev xaiv hauv kev tsim vaj tsev niaj hnub thiab kev tsim khoom.

Nov yog qhov nws ua haujlwm li cas.

1.Fiber Xaiv: Nyob ntawm daim ntawv thov, fibers raug xaiv raws li lawv cov khoom siv kho tshuab. Piv txwv li, carbon fibers muab lub zog siab thiab nruj, ua rau lawv haum rau aerospace thiab automotive daim ntaub ntawv, thaum iav fibers muab lub zog zoo thiab tus nqi-zoo rau cov qauv kev txhim kho.

2.Matrix Khoom: Ib qho polymer matrix, feem ntau nyob rau hauv daim ntawv ntawm cov resin, yog xaiv raws li tej yam xws li compatibility nrog cov fibers, yam khoom uas xav tau, thiab ib puag ncig tej yam kev mob uas composite yuav raug.

3.Composite Fabrication: Cov fibers yog impregnated nrog cov kua resin thiab ces tsim rau hauv cov duab uas xav tau los yog siv raws li txheej hauv pwm. Cov txheej txheem no tuaj yeem ua tiav los ntawm cov txheej txheem xws li tes nteg, filament winding, pultrusion, lossis automated fiber placement (AFP) nyob ntawm qhov nyuaj thiab qhov loj ntawm qhov.

4.Curing: Tom qab shaping, cov resin undergoes curing, uas muaj ib tug tshuaj tiv thaiv los yog kub daim ntawv thov rau harden thiab solidify cov khoom sib xyaw. Cov kauj ruam no xyuas kom meej tias cov fibers tau ruaj khov nyob rau hauv lub polymer matrix, ua kom muaj zog thiab cohesive qauv.

5.Finishing thiab Post-Processing: Thaum kho, FRP composite tej zaum yuav ua tiav cov txheej txheem ntxiv xws li trimming, sanding, los yog txheej kom ua tiav qhov xav tau saum npoo tiav thiab qhov tseeb qhov tseeb.
