摘要

复合材料围巾/台阶修复结构的过程监测和质量评价具有重要意义。本文提出了一种结合数字图像相关（DIC）、脉冲热成像（PT）和相控阵超声（PAU） c扫描的复合材料键合修复结构的形貌和内部缺陷的快速原位评估方法。在磨削过程评价方面，采用无散斑三维数字图像相关（3D-DIC）方法，实现了精度在50 μm左右的定量形貌评价。为了评估键合修复结构，应用了基于dic的形态学分析、脉冲热成像和相控阵超声，并配备了所提出的三维重建算法。采用预设多类型缺陷的试样进行无损检测。本研究对开发低成本、高效率的原位无损检测方法进行复合材料粘结修复监测具有重要的工程应用意义。

Non-destructive inspection of composite bonded repair: integrating morphology analysis, pulsed thermography and phased array ultrasonic

The process monitoring and quality evaluation of composite scarf/step repair structures are of significant importance. In this paper, a method for rapid in-situ evaluation of the morphology and internal defects of the composite bonded repair structures is proposed by integrating digital image correlation (DIC), pulsed thermography (PT), and phased array ultrasonic (PAU) C-scan. For grinding process evaluation, a speckle-free three-dimensional digital image correlation (3D-DIC) method is employed, achieving quantitative morphology evaluation with a precision of around 50 μm. For the evaluation of bonded repaired structures, DIC-based morphology analysis, pulsed thermography and phased array ultrasonics equipped with a proposed three-dimensional reconstruction algorithm is applied. A specimen with preset multi-type defects is used to testing the non-destructive testing (NDT) methods. This study is of great significance for the development of low-cost, high-efficiency and in-situ NDT methods in engineering applications for composite bonded repair monitoring.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
