Abstract

In this paper, infrared thermography (IRT) and ultrasonic C-scan (UT) were used to investigate basalt fiber reinforced polymer (BFRP), carbon fiber reinforced polymer (CFRP) and basalt-carbon fiber hybrid specimens subjected to impact loading. Of particular interest, two different hybrid structures including sandwich-like and intercalated stacking sequence were analyzed. Three different impact energies (5 J, 12.5 J and 25 J) were applied for the evaluation of the impact damage level in the different samples. The inspection by thermographic techniques of this type of laminates is an open matter to be discussed with the scientific audience. The results from pulsed phase thermography (PPT), principal component thermography (PCT) and partial least squares thermography (PLST) applied on raw thermal data were compared to understand the advantages and disadvantages of the two hybrid structures via a comprehensive analysis.
