초록
The object of this study is to investigate the penetration characteristics according to the change of stacking sequences and curvature radius in the composite laminated shell. They are staked to [02/902]S and [0/902/0]s, their interlaminar number are two and four. We manufactured the composite laminated shells with various curvature radiuses. Curvature radiuses of composite shell are 100, 150, 200mm and ∞ (it's meaning flat-plate). In general, the kinetic energy before and after impact increased linearly in all specimens, and the absorbed energy of the specimen [02/902]S with a small number of the interlaminars was higher than specimen [0/902/0]s.
