提出了一种新的基体树脂固化过程监测方法。在该方法中，在材料的内部或表面上构建高频电磁波传输线，并测量固化过程中线路特性的变化。高频电磁波的使用主要目的是利用其短波长获得关于材料特性的不连续性或分布的位置的信息。作为调查的第一步，微带线和平行线的实验装置的构造，并从每个线的反射率的频率特性的变化进行了监测，在固化的环氧树脂之间的线的导体对。还研究了树脂部分填充时的特性变化，以检查检测局部分布或不连续性的可能性。理论计算成功地解释了实验结果。在这项研究中获得的结果表明，潜在的高频电磁波的传输线作为一种工具，用于现场监测固化和其他性能。
A new monitoring method for the curing process of matrix resin is proposed. In this method, a high-frequency electromagnetic wave transmission line is constructed inside or on the surface of a material and changes in the characteristics of the line during the curing process are measured. The use of a high-frequency electromagnetic wave mainly aims at getting information on the position of the discontinuity or distribution of material properties, making use of its short wavelength. As the first step of the investigations, an experimental setup of a microstrip line and a parallel-wire line was constructed, and changes in the frequency characteristics of reflectance from each of the lines were monitored during the curing of epoxy resin between the pair of conductors of the line. Changes in the characteristics when the resin is partly filled were also investigated to examine the possibility of detecting local distributions or discontinuities. The experimental results are successfully explained by theoretical calculations. Results obtained in this study suggest the potential of the transmission line of a high-frequency electromagnetic wave as a tool for in-situ monitoring of curing and other properties.
