Electromagnetic Wave Characteristics of $\textrm{Al}_2\textrm{O}_3$ Woven-Fabric Composites

$\textrm{Al}_2\textrm{O}_3$ Woven-fabric 복합재료의 전자파특성

Recently, GFRP is well known as a structural material for the radome of aircraft. In this paper, we have observed the reflectivity of electromagnetic waves on GFRP reinforced with $\textrm{Al}_2\textrm{O}_3$ woven fabric. The result of the experiment has revealed that the reflectivity of $\textrm{Al}_2\textrm{O}_3$/GFRP composites is remarkably reduced compared with that of GFRP. And it also shows that the electromagnetic wave reflections are greatly influenced by the number of $\textrm{Al}_2\textrm{O}_3$ plies in a specific frequency band. These results are expected to be utilized for the technique of manufacturing a low-reflectivity composite structure.
