Recent Developments in Damage Detection of CFRP Composites Using Non-Destructive Techniques – A Review

This paper presents a comprehensive overview of state-of the art nondestructive testing (NDT) methods specifically applied to carbon fiber reinformed polymer (CFRP) composites. The intent of this survey is to provide valuable guidance and insights to researchers and practitioners encompass in the arena of NDT for CFRP composites. Each NDT method is carefully examined, highlighting its principles, advantages, limitations, and potential applications in the evaluation of CFRP composite structures. The methods discussed in this paper include, but are not limited to, ultrasonic testing, eddy current testing, thermography, radiography, and acoustic emission. Furthermore, the information presented here aims to facilitate the selection and utilization of appropriate NDT methods for effective evaluation and quality assurance of CFRP composite structures along with challenges that researcher may encounter in the practical implementation of this techniques. Finally, an attempt is made to present alphabetically the review of literature on earliest to modern NDT methods published by various authors and how it continues to expand and become a viable technique for damage estimation.
