Thaum lub sij hawm ua cov pa roj carbon fiber ntau, tsis tsuas yog geometric defects tab sis kuj tseem ua cov khoom tsis xws luag ntawm carbon fiber composite cov ntaub ntawv yuav tshwm sim, uas feem ntau muab faib ua ntau yam kev puas tsuaj xws li burrs thiab delamination.
1. Glitch
Lub burr txhais tau hais tias thaum lub qhov yog tsim, txheej fiber ntau tsis muaj kev sib khi quab yuam, thiab lub axial quab yuam thawb tawm sab nraud los ntawm kev xyaum me ntsis ua rau qee qhov tsis muaj fiber ntau burrs tshwm rau hauv qab. Ua tib zoo soj ntsuam qhia tau hais tias cov burrs muaj cov yam ntxwv ntawm kev faib tawm hauv ib cheeb tsam, feem ntau vim tias cov pa roj carbon fiber ntau yog raug rau ob qho tib si shearing thiab stretching quab yuam thaum lub sij hawm drilling txheej txheem. Nyob rau tib lub sijhawm, hauv cov txheej txheem ua haujlwm, cov cuab yeej niaj hnub hnav tsis tuaj yeem txiav cov fiber ntau tam sim ntawd, uas yuav ua rau muaj kev cuam tshuam ntawm burr tsis xws luag.
2. Txheej txheej
Delamination yog hais txog qhov tshwm sim ntawm degumming, sib cais thiab kev puas tsuaj ntawm carbon fiber prepreg plies. Qhov laj thawj tseem ceeb ntawm delamination yog qhov kev ntxhov siab ib txwm nyob nruab nrab ntawm cov khaubncaws sab nraud povtseg thaum bearing static load thiab dynamic load, thiab thib ob, thaum lub ntsug kev nyuaj siab generated thaum lub sij hawm txiav ntau tshaj qhov sib txuas lub zog ntawm matrix thiab fiber, interlayer delamination yuav tshwm sim. Thaum lub sij hawm drilling txheej txheem, kev sib txhuam ntawm lub taub hau cutter thiab carbon fiber tube generates tshav kub, thiab thermal nyhuv tsim nyob ib ncig ntawm lub qhov phab ntsa yuav ua rau delamination.
Yog li yuav ua li cas peb kho cov teeb meem no?
Hais txog cov burrs, tom qab ua tiav cov pa roj carbon fiber ntau, peb tuaj yeem siv cov ntawv xuab zeb los kho cov burrs ntawm cov pa roj carbon fiber ntau kom txo tau cov burrs ntawm cov pa roj carbon fiber ntau.
Hais txog delamination, peb tuaj yeem ua kom qeeb ntawm kev ua haujlwm kom ntau li ntau tau kom txo tau cov cua sov uas tsim los ntawm kev sib txhuam ntawm lub taub hau cutter thiab carbon fiber tube thaum lub sij hawm drilling txheej txheem.
