A study on the electromagnetic performance evaluation of composite specimen based on 3D printer

Abstract

A study has been conducted to evaluate the mechanical performance of various continuous fibers based on 3D printer technology. However, not only mechanical performance but also electromagnetic performance must be considered in aerospace industry. In this study, electromagnetic performance evaluation using a scanning free-space measurement (SFM) system was performed on 3D printed carbon fiber reinforced plastic (CFRP) and glass fiber reinforced plastic (GFRP) specimens in X-band (8.2 ~ 12.4 GHz). It was possible to measure and analyze the electromagnetic performance of composite specimens made by a 3D printer.
