Common Core Materials Siv nyob rau hauv FRP Sandwich Vaj Huam Sib Luag Tsim

HauvFRP Sandwich vaj huam sib luagtshuab siv nyob rau hauv lub tsheb lub cev, modular vaj tse, tub yees enclosures, thiab industrial cov khoom vaj tse, cov tub ntxhais txheej txhais shear hloov tus cwj pwm, vaj huam sib luag thickness stability, thiab huab hwm coj faib thoob plaws lub vaj huam sib luag cross-section. FRP daim tawv nqaij ib leeg tsis tuaj yeem tswj cov txheej txheem sib nrug raws li kev khoov; cov khoom siv tseem ceeb muab cov geometry sab hauv uas txhawb nqa kev thauj mus los ntawm cov tawv nqaij.

Different core materials such as PP honeycomb, PET foam, PU foam, balsa wood, and aluminum honeycomb are selected based on density range, moisture exposure, compressive load, and production process compatibility. Hauv kev lag luam lamination kab, cov tub ntxhais xaiv tau ua tiav ua ntej FRP daim tawv nqaij sib txuas kom phim cov nplaum nplaum viscosity, kho qhov kub thiab txias.

Common Core Materials Used in FRP Sandwich Panel Construction

Cov txheej txheem tseem ceeb hauv FRP sandwich vaj huam sib luag tsis feem ntau nqa tensile lossis compressive loads. Hloov chaw, nws ua peb lub luag haujlwm kho tshuab:

01. Shear HloovHloov shear stress ntawm FRP tawv

02. Tsau Qhov NcaujKhaws qhov chaw ruaj khov ntawm cov tawv nqaij sab saud thiab qis

03. Anti-BucklingTiv thaiv daim tawv nqaij buckling nyob rau hauv khoov thiab vibration

Thaum lub sij hawm khoov vaj huam sib luag, sab sauv FRP ntawm daim tawv nqaij muaj kev nyuaj siab thaum cov tawv nqaij qis muaj zog tensile. Cov khoom siv tseem ceeb faib tawm cov quab yuam hla nws cov qauv sab hauv, tiv thaiv qhov chaw deformation.

Hauv kev tsim khoom, cov nplaum yog siv los ntawm FRP tawv thiab cov tub ntxhais qhov chaw siv cov txheej txheem los yog cov tshuab txau, ua raws li lub tshuab nqus tsev ntawm kev tswj xyuas kom muaj kev sib cuag thoob plaws hauv cov tub ntxhais interface.

Ua los ntawm extruding polypropylene nplooj ntawv thiab nthuav lawv mus rau hauv ib hexagonal cell qauv los ntawm thermal forming. Hom kev lag luam specifications muaj xws li:

Qhov ceev: 60-120 kg / m³Thickness: 6-100 hliCell Loj: 3-12 mm

Txhua hexagonal cell phab ntsa ua haujlwm raws li txoj kev hloov pauv uas faib cov khoom hla lub vaj huam sib luag tuab. Tsis zoo li cov ntaub ntawv polymer, PP honeycomb txo cov khoom ntim tas li thaum tswj kev sib cais ntawm FRP tawv.HolyCoremuab dimensionally tswj CNC nesting layouts kom txo trimming poob.

Ua los ntawm cov khoom siv polyethylene terephthalate los ntawm cov txheej txheem ua npuas dej thiab ua kom txias uas tsim cov txheej txheem kaw {{0} cell. Qhov ceev feem ntau yog li ntawm 60-200 kg / m³ nyob ntawm qhov yuav tsum tau ua rau compression.

Lub kaw -cov qauv ntawm tes txwv kev nqus dej los ntawm kev thaiv txoj hauv kev capillary, tso cai rau cov khoom tiv thaiv kev nkag mus ntawm cov dej noo thaum lub sij hawm condensation cycles hauv cov tub yees tsheb thauj mus los. PET ua npuas ncauj hloov compressive loads los ntawm cov cell deformation tsis yog cov qauv ntawm cov qauv. Lamination yog ua raws li lub tiaj tiaj hauv qab 70℃kom tsis txhob tawg ntawm tes.

Rigid polyurethane ua npuas ncauj yog tsim los ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates (qhov ceev 30-80 kg / m³). Nws feem ntau tiv thaiv thermal hloov thaum txhawb nqa nruab nrab ntawm qhov txias -chain chaw (-18℃rau +5℃). Nyob rau hauv lub sij hawm ntev static mechanical loading, nws tuaj yeem nthuav tawm creep deformation.

Ua los ntawm ntuj ntoo nrog longitudinal fiber ntau orientation (density 100-200 kg/m³). Nws muab anisotropic mechanical zog thiab siab compression tsis kam raws cov nplej. Yuav tsum nruj ntug sealing; Txwv tsis pub, dej ingress tuaj yeem taug kev raws txoj kab, ua rau o thiab poob ntawm shear hloov peev xwm.

Tsim los ntawm kev nthuav cov ntawv sib txuas ntawm txhuas ntawv ci rau hauv hexagonal hlwb (qhov ceev 20-80 kg / m³). Cov qauv hlau ua kom muaj zog nruj heev- rau- hnyav ua haujlwm tab sis tuaj yeem txhim kho corrosion hauv cov av ntub lossis ntsev- qhov chaw raug yog tias kev kho deg raug tshem tawm. Yuav tsum tau epoxy kev sib khi zoo.
