Infrared thermographic detection and characterisation of impact damage in carbon fibre composites: results of the round robin test
Year: 1998
Type: conference-paper
Abstract: Results of inspecting an impact damaged carbon fibre composite specimen are reported.Several physical test procedures and processing .algorithmshave been analysed within the framework of the international Round Robin Test.A statistical means for rating non-destructive testing techniques is proposed to convert otiginal infrared images to defect maps that are of special interest for end-users.The :potentials of the techniques for oharacterising shape and depth distribution of impact damage in carbon fibre composites are discussed, 'including comparison with ultrasonic C-scan results.* A maxigram contains maximum temperature signals over a defect even appeared at different times ** A normalised image appears as the result of dividing a source image by the image at the end of heating *** A magnitude image provides distribution of magnitudes at a particular frequency in the Fourier domain **** A phasegram provides distribution of phases at a particular frequency in the Fourier domain
