Abstract
An unbalanced, sandwich composite structure consisting of TI 6AL-4V and GRP (Glass Reinforced Plastic) skins with a phenolic honeycomb core is being considered for construction of a surface ship mast which will enclose critical shipboard equipment. Stability of the structure is one of the major concerns in the design process. This research focuses on analytical and experimental studies of an unbalanced composite sandwich beam subject to a compressive axial load. The limit load of each skin material separately, and two failure modes of the sandwich construction (general buckling and core shearing), are measured in the laboratory. An analytical model is developed for predicting the limit load of the unbalanced, sandwich composite configuration.
