Honeycomb sandwich qauv muaj vaj huam sib luag, honeycomb thiab nplaum.
Ntawm cov ntaub ntawv honeycomb sandwich, vaj huam sib luag cov ntaub ntawv suav nrog FRP, aluminium alloy, carbon fiber ntau cov ntaub ntawv.
Cov pa roj carbon fiber ntau honeycomb sandwich vaj huam sib luag tau dav siv tam sim no. Tsis tas li ntawd, nrog rau kev nrhiav tus nqi qis, epoxy resin-raws li carbon fiber composites feem ntau yog siv.
Vaj huam sib luag khoom
Lub luag haujlwm tseem ceeb ntawm lub vaj huam sib luag yog ua kom tau raws li qhov yuav tsum tau ua ntawm axial dabtsi yog khoov thiab hauv-plane shear loads. Hauv cov chaw lag luam uas tau muab cov kev pabcuam customized, yuav luag txhua tus siv carbon fiber prepreg resin khoom panels, uas tuaj yeem ua tau raws li qhov xav tau ntawm lub teeb yuag, siab zog, rwb thaiv tsev kub, thermal rwb thaiv tsev, electromagnetic shielding, thiab lwm yam, ntawm chav kawm, xaiv cov panels. tuaj yeem raug xaiv raws li qhov xav tau tiag tiag ntawm aluminium alloy, iav fiber reinforced yas thiab lwm yam ntaub ntawv.
Honeycomb sandwich khoom
Feem ntau siv cov ntaub ntawv honeycomb yog cov ntaub ntawv aluminium honeycomb, aramid honeycomb cov ntaub ntawv, pp honeycomb cov ntaub ntawv.
Vim tias cov khoom siv aramid honeycomb tsis yog-conductive, tsis muaj teeb meem galvanic corrosion, tab sis kuj ua kom tau raws li qhov yuav tsum tau muaj kev haus luam yeeb, kev tsis sib haum xeeb hauv zos yog me dua li aluminium honeycomb, yog li nws tau siv ntau dua. Aluminium honeycomb cov ntaub ntawv feem ntau yog siv rau hauv JY thawv, los nag vaj tse thiab lwm yam khoom, thaum pp honeycomb cov ntaub ntawv yog siv nyob rau hauv high-end kho mob teb.
Cov nplaum nplaum
Adhesive yog ib yam khoom tseem ceeb rau kev tsim cov khoom siv honeycomb sandwich, uas muaj kev cuam tshuam zoo rau cov khoom siv thiab cov txheej txheem ntawm honeycomb sandwich structural cov ntaub ntawv.
Cov nplaum nplaum tuaj yeem muab faib ua epoxy, acid maleimide, cyanate ester, polyimide. Raws li hom matrix.
Vim cov chav kawm epoxy muaj kev ua tau zoo dua, nws txoj kev txhim kho muaj lub siab tawv, yog siv dav hauv cov qauv aviation.
Acid maleimides thiab polyimides feem ntau yog siv rau hauv cov qauv uas muaj qhov kub thiab txias.
Cyanate esters feem ntau yog siv rau hauv gluing ntawm cov qauv ua haujlwm xws li radar kav hlau txais xov vim lawv cov khoom zoo dielectric.
