摘要：

Optimal fiber orientations and layer thicknesses of antisymmetric, angle-ply lami nates are determined with the objective of maximizing the buckling temperature subject to an equal mass or equal thickness constraint. The laminated plate is constructed as a sandwich hybrid structure which is made of outer layers of high-modulus fiber composite material and inner layers of low-modulus fiber composite material. Numerical results are given for graphite/glass and boron/glass material combinations. Comparative studies of hybrid and nonhybrid laminates indicate that the results for hybrid cases do not always fall between those of nonhybrid cases. Moreover, the hybrid construction, as compared to a single-material construction, is found to improve the thermal stability of the structure in some cases. Optimal ply angles are found to display several jump discontinuities when plotted against the aspect ratio. © 1990 Taylor & Francis Group, LLC.
