摘要

本研究利用太赫兹光谱和微计算机断层扫描（micro-CT）技术研究了嵌入光纤和光纤布拉格光栅（FBG）传感器的增材制造（AM）碳纤维增强聚合物（CFRP）复合材料的内部结构。由于碳纤维的高导电性，太赫兹光谱在CFRP中的应用面临着重大挑战，需要仔细优化检测参数。相反，micro-CT利用其更深的穿透能力和高分辨率成像，为CFRP复合材料提供准确、详细的内部成像。太赫兹光谱检测嵌入光纤对AM CFRP结构的影响，而micro-CT通过生成内部结构的详细3D表示，有效识别光纤的精确位置。这些发现强调了基于特定材料特性选择适当的无损检测（NDT）方法的重要性，表明micro-CT是太赫兹光谱的宝贵补充工具，可以在材料科学、医学和工程领域实现对CFRP复合材料的全面评估。

Structural analyses of additively manufactured carbon fiber reinforced polymer with embedded fiber optic using THz spectroscopy and micro-computed tomography

This study examines the internal structure of additively manufactured (AM) carbon fiber reinforced polymer (CFRP) composites embedded with fiber optics with fiber Bragg grating (FBG) sensors using THz spectroscopy and micro-computed tomography (micro-CT). Due to the high conductivity of carbon fiber, the application of THz spectroscopy to CFRP faces significant challenges, necessitating careful optimization of inspection parameters. Conversely, micro-CT leverages its deeper penetration capabilities and high-resolution imaging to provide accurate and detailed internal imaging of CFRP composites. THz spectroscopy detects the influence of embedded fiber optics on AM CFRP structure while micro-CT excels by producing detailed 3D representations of the internal structure, effectively identifying the fiber optic precise location. These findings highlight the importance of selecting appropriate non-destructive testing (NDT) methods based on the specific material properties, demonstrating that micro-CT is an invaluable complementary tool to THz spectroscopy to achieve thorough assessment of CFRP composites in materials science, medicine, and engineering.

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
