In this study, production of radar absorption material was carried out for stealth applications in military technology. Absorbance was stuied by using a vector network analyzer (VNA), which measures the values over a frequency range and provides the results in the form of S-parameters. Mold filling and segregation of the epoxy matrix composite was numerically simulated and validated. The numerical simulations of the mold filling properties were carried out by using the Moldex3D in order to investigate void formation (air trap), and carbon nanotube orientation. In addition, the finite element method (FEM) based numerical simulation technique was also carried out using the ANSYS high-frequency structure simulator (HFSS) in electronic desktop in order to investigate radar absorption properties of the composites. Numerical simulation results were compared with experimental results. Distribution of the iron powders is uniform in the epoxy matrix. Increasing iron powder content increased the Young’s modulus and slightly decreased the impact energy of the composite specimens. Increasing carbon nanotube content increased the Young’s modulus and impact energy.
