Abstract
RADAR Absorbing Structure (RAS), one of stealth technologies, is a multifunctional composite that is capable of supporting load and absorbing electromagnetic waves. In order to supplement the shortcomings of the existing RAS, a hybrid RAS in which the short carbon fiber layers were inserted has been proposed. However, the inserted short carbon fiber layers may affect the mechanical properties of the structure. Therefore, this study measured the interlaminar shear strength (ILSS) of the hybrid RAS with the inserted short carbon fiber layer. The ILSS of hybrid composite with different areal densities of the short carbon fiber layer was measured to investigate the effect of changes in the areal density of the short carbon fiber layer on the ILSS of the structure. In addition, the ILSS of the 4 kinds of the hybrid RAS were measured and compared with the ILSS of glass/epoxy. As a result of the measurement, it was confirmed that the short carbon fiber layer did not significantly affect the ILSS of the hybrid composite and the hybrid RAS.
