摘要
Abstract
Based on composite advanced stiffened grid structure(AGS),in this paper,a novel absorbing/loading integrated composite grid structure is studied and fabricated. The influence of the side length and the height of AGS on its absorbing properties are studied by taking the equal grille as cell structure. It is concluded that the increase in height enhances the absorbing properties of AGS,while the changes in length of cell has little effect on the absorbing properties. In addition,when the height matches the side length,the obtained composite AGS exhibited broadband absorption in 11.5GHz~18GHz with the reflection loss below-10 dB, including the strong absorption peak at 16.2GHz with the maximum reflection loss of-17.35 dB. Additionally,the nominal shear stress of the three-point bending unit cell and the nominal compressive strength of the unit cell are 5.62 MPa and 61.5 MPa,respec?tively.关键词
