Abstract: The design of layup angles in the laminate of the radome is directly related to the overall safety of the structure. Modern commercial software can conduct simulation analysis relying on the predefined layer designs. These predefined layer angles could be designed specific to the particular mesh and models, but this kind of layer design lacks the flexibility and the versatility. This paper uses the geometrical theory and design programs to transfer the longitudinal and latitudinal directions of planar woven fabric on the three dimensional surfaces of the radome to make layer angle designs of the woven glass fabric, and to project the directions onto the models of the finite element model to determine the angles relative to the every specific element. The methodologies in this paper endows the layer design with an obvious and versatile process. It also adds the flexibility of the layer angle calculation and breaks the reliance on different software.
