1、 These thicker laminates are more difficult to infuse and the exotherm development of traditional epoxy systems can lead to exotherm wrinkles in spar caps.
但这些较厚的层压板不易进行灌注，同时，由于传统环氧系统的固化放热还会导致在主梁生产过程中产生起皱等品质缺陷。

2、 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。
