effect of electromagnetic wave irradiation on the radar multilayer structures

the purpose of this study is to understand a correlation between interlaminar delamination and radar absorbing performance of composite radar absorbing structures (ras). in this study, a multi-layer dallenbach radar absorber with glass/epoxy and glass/epoxy-multiwall carbon nanotubes (mwcnt) was designed. based on the design, test specimens were fabricated and the ‘split specimen’ test method was introduced. the reflection loss of the specimen for normal incident em waves in the x-band was measured. the measurement and analysis results verified that the changes in the thickness-wise location and thickness of the delamination altered the magnitude as well as the resonance frequency of the reflection loss. the purpose of this study is to understand a correlation between inter laminar delamination and radar the purpose of this study is to understand a correlation between interlaminar delamination and radar based on the design, test specimens were fabricated and the ‘split specimen’ test method was introduced.
