PP Honeycomb Core vs Aluminum Honeycomb: Key Differences Explained

PP Honeycombcore yog ib lub cellular vaj huam sib luag tsim los ntawm thermoplastic polypropylene nplooj ntawv sib koom ua ke ntawm cov npoo rau hauv hexagonal hlwb, nrog thicknesses li ntawm 10 hli mus rau 50 hli thiab cell diameters ntawm 3 hli mus rau 10 hli.

Aluminium honeycomb core muaj nyias aluminium foils, 50-100 µm tuab, nthuav thiab sib koom ua ke rau hauv hexagonal hlwb nrog txoj kab uas hla ntawm 3 hli mus rau 6 hli, tsim cov vaj huam sib luag feem ntau 10-40 hli tuab.

Ob leeg cov ntaub ntawv tsim cov khoom vaj huam sib luag thaum sib txuas rau cov nplooj ntawv ntsej muag, tab sis PP cores ua tiav qhov nruj feem ntau los ntawm - dav hlau shear nyob rau hauv cov phab ntsa yas, hos aluminium cores hloov compressive thiab shear loads ntawm cov phab ntsa hlau.

Nyob rau hauv PP honeycomb, thov compression rog yog faib los ntawm hexagonal cell phab ntsa, uas khoov thiab nqus zog hauv zos thaum tswj vaj huam sib luag rigidity.

Nyob rau hauv aluminium honeycomb, cell phab ntsa tiv thaiv dabtsi yog khoov thiab buckling nyob rau hauv compression thiab muab ntau dua modulus stiffness.

Shear loads nyob rau hauv PP cores induce yas deformation nyob rau hauv lub cell phab ntsa ntawm 50-150 kPa, thaum txhuas cores xa shear rog mus txog 2-5 MPa nyob ntawm cov ntawv ci thickness thiab cell loj.

Cov kev sib txawv no txhais cov cwj pwm ntawm vaj huam sib luag nyob rau hauv khoov thiab torsion nyob rau hauv lub teeb yuag.

PP cores yog tsim los ntawm cov nplooj ntawv polypropylene, 30-150 µm tuab, thermally bonded ntawm 170-200 degree.

Aluminium cores yog fabricated los ntawm txhuas alloy 3003 los yog 5052 foils, 50-100 µm tuab, nthuav mechanically thiab bonded siv nplaum los yog brazing.

PP cores tuaj yeem suav nrog cov nplaim hluav taws xob ntxiv xws li ATH ntawm 5-15 wt% rau kev ua raws li UL94 V-0.

Aluminium cores tiv taus qhov kub txog li 300℃hauv qhov chaw qhuav tab sis tuaj yeem corrode nyob rau hauv qhov chaw ntub dej los yog dej ntsev tshwj tsis yog coated nrog anodized lossis polymer txheej.

PP honeycomb panels yog siv nyob rau hauv lub automotive Cheebtsam, lub teeb yuag thauj ntim, thiab aerospace pem teb panels, feem ntau nyob rau hauv kub -20℃mus rau 80 degree, txheeb ze av noo mus txog 95%, thiab compressive loads txog 150 kPa.

Aluminium honeycomb panels yog siv nyob rau hauv aerospace structural panels, nkoj bulkheads, thiab cua turbine hniav, ua hauj lwm nyob rau hauv -50℃mus rau 250 degree, compressive loads 0.5-2 MPa, thiab shear stress txog 5 MPa.

Cov kev ua tsis tiav muaj xws li cov buckling hauv zos hauv aluminium cores thiab yas yielding lossis delamination hauv PP cores thaum cov nplaum nplaum tsis txaus.

PP Honeycomb Core Vs Aluminum Honeycomb: Key Differences Explained

PP honeycomb coresyog sib txuas ntawm cov ntawv sib xyaw lossis txhuas lub ntsej muag siv epoxy lossis polyurethane nplaum. Alignment ntawm cell orientation yog ib qho tseem ceeb los tiv thaiv tsis sib xws shear faib. Aluminium cores tau sib xyaw ua ke zoo ib yam, tab sis yuav tsum tau ua tib zoo saib xyuas cov ntawv ci saum npoo kom tsis txhob galvanic corrosion. Kev tshuaj xyuas niaj hnub suav nrog kev tshuaj xyuas cov phab ntsa ntawm tes, cov nplaum delamination, lossis vaj huam sib luag warping. Kev hloov pauv yuav tsum tau tshem cov nplooj ntawv ntsej muag, tshem tawm cov tub ntxhais, thiab rov ua dua nrog tib lub xov tooj ntawm tes taw thiab tuab.

Lawv ua haujlwm ntawm −20℃thiab 80 degree, hloov shear loads ntawm lub ntsej muag nplooj ntawv thaum tswj vaj huam sib luag thickness. Cov qauv thermoplastic tiv thaiv cov dej noo thiab tsis txhob xeb, ua kom yooj yim rau kev sib txuas rau FRP, aluminium, lossis coated steel tawv.

Aluminium honeycomb coresmuab siab zog, compressive zog, thiab kub kam rau ua, ua rau lawv haum rau aerospace pem teb panels, marine bulkheads, thiab industrial enclosures. Raws li cov alloy thiab cell geometry, lawv tuaj yeem ua haujlwm siab tshaj 150℃thiab tiv taus compressive lossis shear loads uas yuav deform polypropylene cores. Kev kho deg yuav tsum tau nyob rau hauv qhov chaw ntub dej lossis ntug hiav txwv kom tiv thaiv corrosion.

Vaj huam sib luag thickness thiab cov qauv tsimKev xaiv cov khoom siv cuam tshuam: PP cores tso cai rau cov vaj huam sib luag tuab nrog qhov hnyav tsawg, thaum txhuas cores ua tiav siab nruj thiab compressive tsis kam hauv cov txheej txheem nyias. Cov kws ua haujlwm tseem yuav tsum xav txog hom kev ua tsis tiav: PP cores tuaj yeem ua tsis tiav ntawm cov phab ntsa ntawm tes los yog delamination, thaum aluminium cores yuav ntsib cov ntawv ci, qaug zog tawg, lossis corrosion yog tias tsis tiv thaiv.
