GJ't Hart [6] tau kawm txog kev siv cov xim tha xim ntau ntawm cov xim F-16 fighter sib tsoo thiab ntsuas lawv. Cov khoom sib xyaw yog carbon fiber / epoxy composite (AS4 / 3501-6), txheej txheej sab nrauv yog npog nrog cov iav fiber ntau, primer yog epoxy resin, thiab cov topcoat yog polyurethane hom, primer thiab topcoat. Lub thickness ntawm lub laser yog 80 ~ 100μm, lub laser siv yog CO2 nruam, lub zog tso zis yog 2kW, tib lub plhaub repetition tus nqi yog 200Hz, thiab cov lens zog ceev yog 8J / m2. Cov kev tshwm sim qhia tau hais tias qhov xim laser xim tshem tawm yog xaiv rau kev tshem tawm ntawm cov xim muaj xim, lub tsho tiv thaiv sab nraud tuaj yeem raug tshem tawm thiab cov qub yuav khaws cia, thiab lub tsho loj thiab cov pib nqa tuaj yeem raug tshem tawm ua ke. Cov xim laser xim tshem tawm yog ceev, uas tuaj yeem mus txog 3 ~ 5 zaug ntawm qhov kev rho tawm ntawm PMB, uas txuag cov txheej txheem. Los ntawm kev saib xyuas qhov kub ntawm cov khoom sib xyaw thaum muab cov xim tshem tawm, qhov kub ntawm cov khoom siv puas tau tsis dhau 80 ° C thaum lub caij tshem tawm cov xim laser.
Yutaka Iwahori li al. [7] tau kawm txog cov kev hloov ntawm cov txheej txheem ntawm cov roj fib laminates tom qab laser tu. Lub substrate siv rau hauv txoj kev tshawb no yog T300 npuag / epoxy composite, cov txheej yog epoxy primer + polyurethane topcoat, thiab TEA CO2 laser siv rau xim tshem tawm. Nyob rau ntawm qhov chaw ua haujlwm ntawm kev sib tw zoo li qub tom qab laser xim raug tshem tawm, lub zog tensile, tensile modulus, compressive zog thiab compressive modulus ntawm laminate composite ua ntej thiab tom qab kev tshem tawm xim tsis hloov ho, uas yog hais tias, lub laser Kev rhuav tshem cov xim tsis yog ua rau txo qis hauv cov khoom siv hauv cov roj carbon fiber ntau.
US Air Force thiab Environmental Safety Technology Certification Program (ESTCP) tau tshawb nrhiav kev tshawb fawb txog kev tshem tawm cov xim ntawm kev siv cov xim laser xim ntawm cov hlau thiab cov tsis muaj hlau [8]. Qhov project no tau tsim tawm ntau hom lasers (250W TEA CO2 laser, 40W Nd: YAG laser thiab 120W Nd: YAG laser) thiab ntau yam khoom siv aviation hauv laser tsis sib txawv (2024 T-3 aluminium alloy, 7075 T-6 aluminium). Laser raug tshem tawm ntawm cov xim hlau zom zaws, 4130 steel, cov ntaub ntawv muaj ntaub ntawv, Kev siv fiber ntau, carbon fiber / epoxy composites, los ntawm kev kawm cov xim tshem tawm thiab deg lub tsho loj hloov Lub zog ntawm lub substrate hloov , thiab adhesion cov khoom ntawm cov xim txheej tom qab lub substrate re-sprayed tom qab kev tshem tawm xim. Cov kev tshawb fawb pom tau tias yog xaiv cov xim laser xim tshem tawm txoj kev tsis haum, cov xim laser xim tshem tawm tau hloov cov xim xim tshem tawm cov txheej txheem nyob rau hauv daim ntawv thov ntawm xim xim tshem tawm ntawm ntau yam khoom ntawm aircraft.
SC Hong thiab al [9] siv Q-switched nruam laser nrog ntau lub wavelengths kom tshem tawm cov nplaim ntawm co-coated carbon fiber / epoxy txim. Cov kev tshawb fawb pom tau tias cov coatings thiab composites tuaj yeem tiv taus ntau lub zog lens zog. Qhov kev puas tsuaj laser zog ntim ntawm cov nplaim hluav taws xob (reinforced resin matrix composite) (CFRP) yog 51 mJ / cm2, thaum lub laser zog ceev ntim ntawm CFRP uas tsis muaj qhov sprayed yog 102.45 mJ / cm2, uas qhia tau tias thaum lub laser energy density yog thaum tswj ntawm 51 thiab 102.45 mJ / cm2, nws yog ib qho ua tau kom tshem tawm cov coating rau ntawm lub CFRP tsis ua rau lub substrate.
