Small fractures in the composites move through the material and rupture the microcapsules, releasing the healing agent.

复合体系中的小裂纹穿过材料并使微包覆物破坏，从而释放出愈合助剂。

Due to their different location in the composites, these nano phases have different effects on the aluminum based composites.

由于这些相的形成条件、形成区域不同，对复合材料性能的影响也不同。

Healing in the composites is achieved through the addition of a microencapsulated healing agent and a catalyst to the matrix polymer.

在复合体系中的愈合作用是通过添加微包覆的愈合剂和一种催化基体聚合物的催化剂实现的。
