摘      要：Numerous non-destructive techniques are being investigated for assuring quality of the adhesive *** research presented here is focused on non-destructive assessment of carbon fibre reinforced polymer(CFRP)*** surface condition directly influences the performance of adhesive *** structural joints should ensure safe usage of a ***,some modifications of the surface may lead to weak bond that cannot carry the desired *** is why there is a search for methods of surface assessment before ***,reliable techniques are required to allow to verify the integrity of the adhesive bond after manufacturing or bonded *** focus on the laser induced fluorescence(LIF)method for assessing the surface *** LIF is a noncontact measurement *** the context of adhesive bond assessment the electromechanical impedance(EMI)method is *** EMI uses surface bonded piezoelectric sensors for excitation and *** investigated samples were made of CFRP *** samples were treated at elevated *** influence of the thermal treatment was studied using *** thermal treatment at 220℃could be clearly distinguishedrom the rest of the considered *** thermally treated plates were bonded to untreated plate and then they were measured with the EMI method to study the influence of the treatment on the adhesive *** changes of EMI spectra were significant for the treatment at 280 ℃ and for some thermally treated samples that were later contaminated with de-icing fluid.
