1. Project Introduction

In response to the needs of large-area rapid scanning of large components such as composite materials and automated testing of complex structures such as R angles, this project develops a multi-axis motion scanning system and supporting motion control software based on ultrasonic phased array technology to combine the motion position signal with ultrasonic data acquisition and realize scanning and imaging of internal defects of large components. Using high-precision positioning, the FPGA adaptive algorithm can realize coupled adaptive detection of composite materials with arbitrary curved shapes. At the same time, using the electronic scanning characteristics of phased array probes, the detection of large-area plates can be completed at high speed, and ultimately accurate detection of multiple complex composite materials. Internal defects such as delamination, holes, inclusions, and debonding in the R corner area of composite materials can be calculated, and the porosity, density distribution, etc. of the composite material can be calculated, as well as the quality assessment of specific areas.
