1, kev sib tham kho thaj
Fuselage thiab tis qauv ntawm cov dav hlau tshiab yog ua los ntawm cov khoom laminates, externally txhawb nrog kev sib koom tes nrog cov kab teeb ntev. Cov khoom khib lav muaj ntau txheej ntau dua cov vaj huam sib luag ntawm honeycomb sandwich cov qauv. Stamped kho cov txheej txheem rau cov khoom Laminate txheej qauv zoo ib yam li cov khoom fiber ntau, kev muag khoom ntawm cov pa roj carbon, tab sis nrog qhov sib txawv me me.
Cov khoom lag luam stamped tuaj yeem ua nrog kev kho theem ntaiv lossis, feem ntau, nrog rau kev kho tsis zoo (ua kom zoo nkauj). Lub kaum sab xis ntawm kev txiav txim siab yog feem ntau yog yooj yim rau kev thauj mus rau hauv kev sib koom ua ke thiab tiv thaiv cov nplaum kom dim. Qhov no txhais tau rau hauv ib qho tuab rau ntev piv rau 1:10 txog 1:70. Vim tias kev soj ntsuam kev kho uas yuav nyuaj, kev txhim kho kev sib raug zoo uas yuav tsum tau kho dua tshiab rau kev tswj hwm siab dua, cov neeg ua haujlwm zoo dua thiab kev nyiam huv ntau dua li kev kho kom zoo.
Los ntawm lub thauj mus hloov chaw hloov chaw, cov kev sib koom ua ke yog ua tau zoo dua vim tias nws txo cov txheej txheem ntawm poj niam nrog cov ncej nruab nrab ntawm lub thaj. Txawm li cas los xij, qhov kev teeb tsa no muaj ntau qhov tsis zoo thaum ua haujlwm rov qab.
Ua ntej, ntau npaum li cas ntawm acoustic-rhiab cov ntaub ntawv yuav tsum tau muab tshem tawm kom muaj lub kaum me me taper.
Thib ob, cov hloov txheej yuav tsum yog nteg tawm heev thiab muab tso rau hauv kev kho seam.
Qhov thib peb, kev kho cov txheej hloov tuaj yeem ua rau muaj kev txo qis hauv lub zog yog tias tsis kho hauv autoclave.
Plaub, cov nplaum yuav lo rau hauv qab ntawm kev sib koom tes, tsim cov kab tsis sib haum xeeb. Qhov no tuaj yeem raug txo qis los ntawm cov kauj ruam me me rau kev kwv yees lub suab sib dhos.
Rau cov laj thawj no, tshwj tsis yog ib feem ntawm qhov chaw kho, hom kev kho no feem ntau yog tso rau hauv ib qho chaw twg tuaj yeem tso rau hauv ib qho chaw twg tuaj yeem tso rau hauv ib qho chaw twg tuaj yeem ua rau ib feem uas muaj zog raws li lub chaw qub.
Muaj ntau txoj kev kho sib txawv rau cov lus laminates. Lub thaj tuaj yeem kho tau ua ntej thiab tom qab ntawd ob qho tib si sib khi rau niam txiv cov khoom. Txoj kev no yog ze tshaj plaws rau kev kho tus ntsia liaj qhov rooj. Raws li muaj nyob hauv daim duab 64, ib qho kev npaj txhij tuaj yeem ua rau hauv ib thaj thiab tom qab-kho tib lub sijhawm raws li cov nplaum. Thaj ua rau thaj kuj tseem tuaj yeem kho tau siv cov txheej ntub dej. Kev ntxuav lub voj voog kuj tseem tuaj yeem sib txawv nyob rau hauv lub sijhawm, kho qhov kub thiab kho lub siab, ua tau cov kev sib txuas ua haujlwm tau zoo.

2, kho ntawm composite bevelled vaj huam sib luag
Kauj ruam 1: Kev Tshuaj Xyuas Kev Puas Tsuaj thiab Kev Ntsuam Xyuas
Qhov loj thiab qhov tob ntawm kev puas tsuaj yuav tsum tau kho yuav tsum yog ntsuas yog siv cov kev ntsuam xyuas uas tsim nyog tsis yog (NDE) cov tswv yim. Ntau hom NDE NTEV siv tau rau kev puas tsuaj kev soj ntsuam ntawm cov qauv sib xyaw. Qhov yooj yim txheej txheem yog pom kev pom zoo, qhov twg whitening vim yog qhov kev tawg rau hauv translucent lamination xws li iav-polyester thiab iav eser laminates tuaj yeem siv los qhia cov cheeb tsam ntawm kev puas tsuaj.
Kev kuaj pom tsis yog cov txheej txheem yog qhov tsis muaj kev puas tsuaj los ntawm cov xim tsis zoo, thiab kev puas tsuaj rau hauv cov chaw tsis muaj zog xws li carbon fiber thiab aramid laminates. Cov txheej txheem nrov yog tus kais kuaj, qhov twg yog cov khoom siv hnav, xws li npib lossis rauj, yog siv los nrhiav kev puas tsuaj. Cov txiaj ntsig tseem ceeb ntawm tus kais kuaj yog tias nws yog qhov yooj yim thiab tuaj yeem siv tau los tshawb xyuas cov chaw loj. Coj mus rhaub kev xeem yog feem ntau siv los xyuas cov kev puas tsuaj rau kev puas tsuaj rau saum npoo, tab sis nws tsis muaj tsawg dua li qhov delamination yog nyob ntawm qhov tob hauv qab saum npoo. Lub khob hliav tshuaj mus kuaj yog tsis muaj txiaj ntsig rau kev ntes lwm hom kev puas tsuaj, xws li resin tawg thiab tawg fibers.
Ua kom paub ntau dua NDE cov tswv yim rau kev tshawb xyuas cov composites yog kev sim ntsuas, x-tshav radorography, thermography, thiab ultrasound. Ntawm cov tswv yim no, ultrasound yog cov kev sib cav tshaj plaws thiab cov tswv yim thiab feem ntau yog siv los ntsuas kev puas tsuaj. Ultrasound tuaj yeem siv los tshawb xyuas cov khaubncaws sab nraud me me nyob hauv qab qhov chaw, tsis zoo li pom kev pom kev thiab kev sim ua kom pom kev.
Kauj ruam 2: Tshem cov khoom puas
Ib zaug ntawm thaj chaw puas txee kom raug txiav txim tau txiav txim siab tau txiav txim siab, lub laminate yuav tsum tau muab tshem tawm. Ntug ntawm lub suab raminate yog ces taper rau lub kaum sab xis ntiav. Cov kab sib dhos teraper, tseem hu ua txoj kev txhuam kaum, yuav tsum tsawg dua 12: 1 (<5°) to minimise shear strain along the bondline after repairing the patch. The shallow angle also compensates for some errors in process and other operational variables that may reduce patch adhesion. As shown in Figure 65.

Kauj ruam 3: Npaj Kev Sib Txawv
Lub laminate nyob ze ntawm thaj chaw embedding yuav tsum tau maj mam muab cov xuab zeb thiab cov hmoov av thiab cov dej paug yuav tsum tau muab tshem tawm. Nws raug nquahu tias yog tias thaj chaw teeb tsa tau raug rau ib puag ncig rau lub sijhawm txiav txim siab ntawm lub sijhawm, nws yuav tsum tau ntxuav kom tshem tawm cov kev tsis huv.
Kauj ruam 4: Xyaum / Zaj Duab Zaj Tooling
Lub Rigid Support phaj nrog cov thawj cov qauv ntawm cov qauv sib dhos yog qhov yuav tsum tau ua kom pom tias kev kho muaj tib qho geometry raws li tus qauv ib puag ncig.
Kauj ruam 5: Lamination
Laminated kho yog feem ntau ua tau siv ib qho kev txo qis ntawm cov ply-nyiam tapers. Thaum lub sijhawm kho no lees paub, nws tsim tawm cov chaw muaj txiaj ntsig tsis muaj zog ntawm cov npoo ntawm txhua txheej ntawm kev kho lub interface. Qhov ntau tshaj plaws tuab yaj duab Lamination ua ntej, qhov twg thawj txheej ntawm kev txhawb nqa cov ntaub npog cov chaw ua haujlwm, ua kom muaj zog interfacial kev twb kev sib txuas. Nws ua raws cov chaw tsim khoom SRM cov lus qhia.
Qhov kev xaiv ntawm kev txhawb nqa cov khoom siv yog qhov tseem ceeb kom ntseeg tau tias kev kho tau muaj cov khoom siv tshuab tau txais. Qhov kev txhawb nqa cov ntaub lossis kab xev yuav tsum zoo ib yam li cov khoom siv txhawb nqa siv hauv cov ntawv sau ua ke.
Cov kev qhia fiber ntau ntawm cov txheej txheem txhawb nqa ntawm cov plywood lub zog yuav tsum phim cov khoom qub uas yog tias cov neeg kho tshuab ntawm kev kho yog ze li cov khoom siv qub.
3, Kho ntawm cov npoo tsheb vov thiab chaw hloov chaw
Txoj kev taug ntawm tis ntawm tswj vaj huam sib luag yog qhov raug rau kev puas tsuaj. Lub tsheb 4 ntiv taw yog tshwj xeeb tshwj xeeb rau kev cuam tshuam hauv av thiab tuav, nrog rau xob laim. Kev kho yuav yog qhov nyuaj rau hauv thaj chaw no vim tias kev ua kom zoo nkauj thiab cov ntug kev txhim kho yuav raug kev koom tes. Kho rau honeycomb cores ntawm cov npoo uas puas tau zoo ib yam li cov kev hloov pauv thiab cov khoom tawg uas muaj cov qauv sib tham tau sib tham hauv ib lossis ob lub vaj huam sib luag kho ntu. Qhov kev puas tsuaj yog tshawb nrhiav, cov txheej txheem puas thiab cores tau muab tshem tawm, ib feem yog txheej txheem tshiab, kho kom zoo, kho thiab tshuaj xyuas tom qab kho. Tus nyiam koojtis trace ntug yog qhia hauv daim duab 66.

4, Kho los ntawm kev txhaj tshuaj OV
Resin kev txhaj tshuaj yog siv rau cov khoom laminates ntawm lub teeb ua haujlwm siv nrog kev puas tsuaj me me vim kev ua kom zoo me me. Ob lub qhov tau muab rau sab nraud ntawm thaj chaw delamination thiab cov viscosity qis yog txhaj rau ib lub qhov kom txog thaum lub pas dej ntws tawm ntawm lub qhov. Resin Kev Txhaj Tshuaj Kho yog qee zaum siv hauv Sandwich Honeycomb cov qauv los kho vaj huam sib luag tshem tawm. Qhov tsis zoo ntawm txoj kev txhaj tshuaj tawm yog tias nws yog qhov nyuaj kom tshem tawm cov dej noo los ntawm qhov chaw puas tsuaj vim yog kev txhaj tshuaj, kom ua tiav kev txhaj tshuaj, raws li qhia hauv daim duab 67.
