Dab tsi yog cov txheej txheem ntawm pre-embedding carbon fiber khoom?

Views:52 Author: Linda Tshaj Tawm Sijhawm: 2022-11-07 keeb kwm:

Vim lub anisotropy thiab cov txheej txheem tsim tshwj xeeb ntawm cov khoom siv fiber ntau nws tus kheej, cov matrix tom qab molding yuav tsum tsis txhob raug machined, txwv tsis pub qhov txuas ntxiv ntawm matrix fiber ntau yuav raug puas tsuaj thiab cov khoom siv kho tshuab yuav raug cuam tshuam. Txhawm rau kom ntseeg tau tias qhov tseeb ntawm kev teeb tsa thiab kev ua tau zoo ntawm cov khoom siv fiber ntau sib xyaw, cov khoom siv hlau feem ntau yog muab tso rau ntawm cov pa roj carbon fiber ntau cov khoom sib xyaw ua ntej, thiab qhov tseeb ntawm cov khoom yog lav los ntawm kev ua cov khoom kos.

              Feem ntau ntawm cov embedded qhov chaw yog ua los ntawm titanium alloy cov ntaub ntawv, uas muaj ib tug zoo meej lub zog thiab tshwj xeeb nruj qhov tseem ceeb. Cov hom embedded qhov chaw tuaj yeem muab faib ua qhov chaw sib chwv qhov chaw, tus pin embedded qhov chaw, ntsia hlau embedded qhov chaw, thiab lwm yam raws li kev ua haujlwm sib txawv.

(1) Nto sib cuag embedded qhov chaw

Vim tias qhov kev ua haujlwm tsis zoo ntawm cov fiber ntau, qhov flatness ntawm 100mm × 100mm cheeb tsam tsuas yog li 0.1mm, thiab qhov zoo ntawm qhov chaw thiab qhov ntev ntev tsis tuaj yeem lav zoo. Kev ua haujlwm ncaj qha ntawm fiber ntau matrix feem ntau tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Qhov teeb meem no tuaj yeem daws tau zoo los ntawm kev ntxiv cov khoom sib txuas thaum lub sij hawm tsim cov fiber ntau matrix, thiab tom qab molding, cov khoom embedded tiav los xyuas kom meej qhov zoo ntawm qhov loj me thiab cov duab thiab txoj hauj lwm kam rau ua qhov tseem ceeb.

(2) Pin embedded qhov chaw

Cov ntsia hlau txuas tuaj yeem tsuas yog nruj tab sis tsis nyob. Thaum yuav tsum tau muab tso rau qhov tseeb, tus pin yuav tsum tau siv los xyuas kom meej nws. Cov qauv tsim ntawm qhov sib txuas ntawm tus pin thiab qhov sib txuas ntawm cov xov yog qhov zoo sib xws, thiab nws tseem yuav tsum tau tiv thaiv kom tsis txhob cuam tshuam ntawm rotating thiab txav mus rau axial kev taw qhia. Txhawm rau kom ntseeg tau tias qhov tseeb haum ntawm tus pin thiab tus pin qhov, tus pin qhov feem ntau ua tiav tom qab qhov sib txuas yog sib txuas rau fiber ntau matrix.

(3) Screw embedded qhov chaw

Carbon fiber ntau cov ntaub ntawv yog cov khoom siv unidirectional. Lub zog ntawm threaded qhov ncaj qha ua tiav ntawm cov fiber ntau matrix yog tsawg heev, thiab cov xov hniav tau yooj yim puas. Rau cov khoom uas yuav tsum tau ntsia hlau fastening, ntsia hlau embedded qhov chaw yog tsim nyog. Cov xov ntawm cov ntsia hlau embedded qhov feem ntau yog ua ntej ua ntej thiab tom qab ntawd glued rau hauv fiber ntau matrix. Txhawm rau tiv thaiv kev sib hloov ntawm radial thiab axial ua si ntawm cov khoom sib txuas thaum lub sij hawm ntsia hlau nruj, knurling tuaj yeem ua rau ntawm txoj kab uas hla sab nraud kom muaj zog sib txuas yog tias tsim nyog.

Cov duab ntawm cov khoom embedded yog txiav txim los ntawm cov duab sib txawv ntawm cov fiber ntau matrix thiab cov sijhawm siv sib txawv. Los ntawm kev siv cov kev ntsuas xws li knurling thiab positioning pins nyob rau sab nraud txoj kab uas hla ntawm lub taub hau square flange, cov embedded qhov chaw feem ntau yuav xyuas kom meej tias tsis muaj kev hloov pauv tshwm sim hauv matrix.
