Lub teb chaws Yelemees txhim kho sai, meej, hnav-dawb Laser Perforated CFRP txheej txheem

Tsis ntev los no, cov kws tshawb fawb ntawm Laser Center Hannover (LZH) hauv lub teb chaws Yelemees tshaj tawm txoj kev vam meej ntawm kev siv lub tshuab laser drilling uas tuaj yeem pab txhawb kev ua cov carbon fiber reinforced plastics (CFRP). Qhov no, lawv hais tias, tshwj xeeb tshaj yog muaj txiaj ntsig rau kev siv hauv kev tsim kho lub teeb thiab lub suab rwb thaiv tsev.
Cov khoom sib xyaw xws li carbon fiber reinforced yas (CFRP) yog qhov zoo heev rau kev tsim kho thiab siv, ntawm lwm yam, hauv tsheb thiab dav hlau qauv. Txhawm rau ua kom yooj yim ntawm kev ua haujlwm ntawm CFRP thiab cov khoom siv sandwich, LZH cov kws tshawb fawb, ua ke nrog Invent thiab KMS Technology Center, tau tsim cov txheej txheem tshiab nrog rau kev teeb tsa cuam tshuam.
Nyob rau hauv cov txheej txheem no, lub laser beam yog muab faib mus rau hauv ib nrab kab teeb los ntawm tshwj xeeb tsim diffraction optics thiaj li hais tias nws hits ntau qhov chaw ntawm cov khoom thiab tsim ntau lub qhov nyob rau tib lub sij hawm.
Qhov zoo tshaj plaws, qhov no tuaj yeem ua tiav nrog ntau npaum li 25 feem ntawm kab teeb, txo lub sijhawm xuas nrig ntaus rau ib lub hlis twg ntawm lub sijhawm qub thiab tsawg dua li ib feem kaum ntawm ib lub qhov, ib yam dab tsi uas tsis tuaj yeem ua tiav nrog cov qauv siv, txawm tias qhov loj dua.
Nrog rau cov txheej txheem no, cov kws tshawb fawb tau tsim cov qhov me me li 1.2 hli - 0.25 hli inch. Qhov no ua rau lawv me dua li qhov tam sim no pom nyob rau hauv cov qhaub cij thiab CFRP cov ntaub ntawv siv cov txheej txheem siv tshuab. Qhov siab ntawm kev hloov pauv hauv qhov taub thiab cov qauv kuj tuaj yeem ua tiav yam tsis tas yuav hloov cov cuab yeej, siv cov cuab yeej kho qhov muag tsim los ntawm KMS Technology Center.
Laser microdrilling kuj nthuav dav hauv aerospace sector. Piv txwv li, acoustic cladding ntsiab yog siv nyob rau hauv lub cav kom txo tau lub suab nrov emissions ntawm aircraft. Cov khoom zoo li no feem ntau yog ua los ntawm CFRP lossis CFRP sandwich khoom, uas yog tom qab ntawd muab ntau qhov me me nyob rau thaj tsam loj.
Laser microdrilling yog tsim rau acoustic drilling vim nws yog contactless thiab yog li tsis muaj kev ntxhov siab thiab hnav. Qhov no tshem tawm cov nqi siab vim kev xyaum hnav thiab cov teeb meem zoo tshwm sim los ntawm blunt drilling. Hauv kev ntsuam xyuas acoustic, tus khub ua haujlwm Invent tau ntsuas qhov ua tau zoo ntawm lub laser-drilled sandwich panels li "zoo heev".
