These thicker laminates are more difficult to infuse and the exotherm development of traditional epoxy systems can lead to exotherm wrinkles in spar caps.
Since the isotropy of such laminates holds only for the elastic properties but not for the strength behavior their strength largely depends on the stacking structure.
在板内发生损伤之后，其各向同性性质不再保留，最终强度将依赖于加载方向以及叠层顺序。

In this paper, the interlaminar stress distributions of symmetric composite laminates with a hole are predicted by the three-dimensional elastoplastic finite element method.
