The carbon fiber reinforced polymers are widely used in the different branches of industry, which requires reliable, non-destructive and fast quality control method. Among existed non-destructive methods, the high-frequency eddy current method satisfies these requirements and widely used for quality control of the carbon fiber composites. Here, we propose a novel method for depth detection, which is based on utilization of multi-sensor techniques. The last based on the combination of the different electromagnetic sensors penetrating different depth in composite with the next signals processing and evaluation. Based on this technique, we preform both experimental and numerical study of the proposed concept.
