摘要/Abstract

摘要： 为改善自修复材料中微胶囊的分散性及其对复合材料力学性能的影响，采用KH550 和KH560偶联剂对微胶囊表面进行改性处理，研究自修复微胶囊在玻璃织物增强复合材料（GFRP）的分散性及其弯曲性能。结果表明，用KH560偶联剂处理后，自修复微胶囊在GFRP的分散改善达64.7%，优于KH550处理微胶囊分散性, 但却使得制备的GFRP的弯曲强度降低。通过SEM分析发现，偶联剂处理后微胶囊与树脂基体界面良好。

Abstract: In order to improve microcapsules dispersion and their effect on mechanical strength of composites, two coupling agents namely KH550 and KH560, were applied to modify microcapsules surface, and self-healing microcapsules dispersion in Glass-fiber reinforced plastic (GFRP) as well as their flexural performance were discussed. The results showed that after KH560 treatment, microcapsules dispersion improvement in GFRP reaches to 64.7%, which is better than KH550 treated microcapsules. However, flexural stress of the self-healing GFRP where microcapsules are treated by coupling agent is decreased. According to SEM observations, the interface between microcapsules and epoxy bonds well.
