Abstract

The present invention relates to an integrated system and method for in-situ 3-axis scanning and detecting defects in a CFRP composite (150) being loaded under static and cyclic test conditions. The system comprises a test system integrated with (10) a scanning system (20) that comprises a probe assembly (52) to generate eddy current on the surface of the CFRP composite (150) mounted on the test system, and a 3D scanner assembly (60) for movement of the probe assembly (50) over the entire surface area of the CFRP composite (150) along X-axis, Y-axis and Z-axis. An operator console (70) is connected to the test system and the scanning system (20) for controlling (3) mechanical test process in the test system and for controlling 3-dimensional movement of the probe assembly (52) along X-axis, Y-axis and Z-axis in a synchronous manner. Such system and method achieve (3D) automated and synchronized 3D scanning of the CFRP composite (150) to accurately detect the defects in the CFRP composite (150) before/during/after mechanical testing without interrupting the mechanical test process.
