摘要

本文介绍了一种节能、快速固化碳纤维增强聚合物（CFRPs）的方法，该方法使用了一种优化的涂布器，该涂布器包含了一个多孔贴片单元细胞。通过实验方法引入CFRP的表面阻抗模型，建立了微波能量与复合材料强耦合的可行性。这是通过在复合材料上覆盖一层匹配的高介电常数材料来实现的，厚度约为四分之一波长。值得注意的是，超表面结构被用来创建这个匹配层。我们的研究结果表明，多孔贴片匹配层产生了高度均匀的热分布，使升温速率高达$30~^{\circ}$ C/min。此外，所开发的方法促进了CFRP在小型，经济高效的应用程序中的工业级固化，与高压灭菌器固化的样品相比，其机械性能得到增强。

Rapid and Energy-Efficient Microwave Curing of CFRPs Enabled by Holey-Shaped Metasurface Layers

This article presents an energy-efficient and rapid method for curing carbon fiber-reinforced polymers (CFRPs) using an optimized applicator, which incorporates a holey-patch unit cell. By introducing a surface impedance model for the CFRP through experimental methods, we establish the feasibility of achieving strong coupling of microwave energy into the composite. This is achieved by covering the composite with a matching layer of a high-permittivity material, approximately a quarter-wavelength in thickness. Remarkably, metasurface structures are utilized to create this matching layer. Our results demonstrate that the holey-patch matching layer generates a highly homogeneous heat profile, enabling a ramp-up rate of up to

$30~^{\circ }$

C/min. Furthermore, the developed method facilitates industrial-grade curing of CFRP in small, cost-effective applicators, resulting in enhanced mechanical properties compared with autoclave-cured samples.

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
