Dab tsi yog FRP Sandwich Vaj Huam Sib Luag Thiab Nws Yuav Ua Li Cas?

Hauv cov khoom siv thauj mus los, cov tsev tsim qauv, cov tsheb tub yees, thiab cov khoom siv hauv tsev, vaj huam sib luag thickness feem ntau yuav tsum tau nce ntxiv txhawm rau txhim kho qhov nruj. Cov khoom siv niaj hnub ua tiav qhov no los ntawm kev ntxiv cov khoom siv ntxiv, uas ua rau kom hnyav thiab cov nqi thauj mus los.

FRP sandwich vaj huam sib luagdaws qhov teeb meem no los ntawm cov txheej txheem txheej. Es tsis txhob siv cov tub ntxhais muaj zog, lawv muab cov fiberglass - siv cov tawv nqaij ntxiv nrog cov khoom siv hauv lub cev. Qhov kev tsim kho no tso cai rau cov tuam txhab tswj xyuas vaj huam sib luag thickness thaum txo cov khoom loj. Yog li ntawd, FRP sandwich panels feem ntau muab tso rau hauv lub tsheb lub cev phab ntsa, RV sab vaj huam sib luag, chav huv si, thiab cov tsev ua haujlwm ua ntej.

What Is an FRP Sandwich Panel and How Is It Manufactured?

FRP sandwich vaj huam sib luag yog cov qauv sib xyaw uas muaj peb txheej txheej:

Sab nrauv FRP daim tawv nqaij
Cov khoom siv tseem ceeb
Sab hauv FRP daim tawv nqaij

Cov ntaub ntawv ntawm daim tawv nqaij yog tsim los ntawm fiberglass reinforcement thiab thermosetting resin systems xws li polyester, yas ester, los yog epoxy resin.

FRP daim tawv nqaij

FRP tawv tiv taus tensile thiab compressive rog, thaum lub hauv paus txhawb nqa vaj huam sib luag thickness thiab hloov loads ntawm daim tawv nqaij. Qhov kev teeb tsa no tso cai rau lub vaj huam sib luag tuaj yeem nqa cov khoom siv khoov tsis tas yuav tsum muaj cov qauv tsim sab hauv.

Thaum lub vaj huam sib luag sandwich raug khoov zog, cov txheej txheem sib txawv ua haujlwm sib txawv.

1Sab saum toj FRP daim tawv nqaij absorbs compressive kev nyuaj siab.

2Cov tawv nqaij qis FRP absorbs tensile stress.

3Lub hauv paus hloov shear quab yuam ntawm ob daim tawv nqaij thiab tswj kev sib cais nrug.

Raws li qhov kev ncua deb ntawm daim tawv nqaij nce, lub vaj huam sib luag lub sij hawm ntawm inertia nce. Qhov no tso cai rau cov qauv los tiv thaiv kev khoov nrog cov khoom siv tsawg dua piv rau cov khoom vaj huam sib luag ntawm qhov sib npaug. Piv txwv li, 40 hli sandwich vaj huam sib luag yuav ua tau zoo dua dabtsi yog khoov nruj dua li cov khoom nyias nyias nyias thaum siv cov khoom siv tsawg dua hauv lub vaj huam sib luag.

FRP tawv yog tsim los ntawm fiberglass reinforcement ua ke nrog resin systems. Cov tawv nqaij tuab feem ntau yog li ntawm 0.8 hli mus rau 5 hli nyob ntawm qhov yuav tsum tau ua.

Cov khoom siv txhawb zog:

Txiav strand lev
Woven rov
Multiaxial fiberglass ntaub

Resin Systems:

Polyester cob
Vinyl ester resin
Epoxy cob

Cov tub ntxhais siv feem ntau ntawm cov vaj huam sib luag thickness thiab txiav txim siab qhov hnyav, shear zog, thiab thermal ua haujlwm.

Cov khoom siv tseem ceeb	Hom ntom ntom
PP Honeycomb tub ntxhais	60-120 kg/m³
PET Foam	80-200 kg / m³
PU ua npuas ncauj	30-150 kg / m³

Aluminium Honeycomb	Nyob ntawm daim ntawv thickness

PP honeycomb tub ntxhaisyog tsim los ntawm cov ntawv polypropylene uas tau sib koom ua ke thiab nthuav dav rau hauv cov qauv hexagonal cellular txuas ntxiv. Piv nrog rau cov khoom-cov qauv tseem ceeb, lub cellular geometry txo cov khoom siv vim tias feem ntau ntawm cov ntim sab hauv muaj qhov chaw nyob hauv huab cua.

Kauj ruam 1

FRP Skin Production

Fiberglass reinforcement yog ua ke nrog resin thiab tsim rau hauv cov ntawv siv tes nteg-nce, Nruam lamination, Nqus infusion, los yog Compression molding.

Kauj ruam 2

Kev npaj cov khoom tseem ceeb

Cov khoom siv tseem ceeb uas tau xaiv yog ua tiav los ntawm CNC txiav, ntug trimming, deg tu, thiab tuab pov thawj kom ntseeg tau tias kev thauj mus los zoo ib yam.

Kauj ruam 3

Daim ntawv thov Adhesive

Polyurethane, epoxy, los yog hloov acrylic nplaum yog siv. Kev them nqi tag nrho yog qhov tseem ceeb los tiv thaiv kev ua haujlwm tsis ua haujlwm thiab kev ntxhov siab hauv zos.
