摘要/Abstract

摘要： 本文制备了复合材料蜂窝夹芯结构件和三种孔径的半穿透损伤件,采用挖补工艺对损伤件进行了两种不同体系的修复,并测试了完好件、损伤件和修复件在常温和高温下的力学性能。两种体系修复后测试结果表明,高温修复(同质修复)和中温修复(异质修复)对损伤构件的性能恢复差异较小,但是由于同质修复工艺性差,固化温度高于177℃,容易造成其他构件的损伤,而异质修复工艺性较好、固化温度低,所以采用异质修复工艺能够实现对损伤构件的性能恢复,且适合于外场快速修复。

关键词: 蜂窝夹芯结构, 异质修复, 力学性能

Abstract: Honeycomb sandwich structures and three different aperture semi-penetrating damage parts were prepared in this paper. The damage is repaired by patching technology, including high temperature repair (homogeneous repair) and middle temperature repair (heterogeneous repair). The mechanical properties were tested at room temperature and high temperature. The results show that there is little difference on performance recovery of the damaged specimens between homogeneous repair and heterogeneous repair. And due to the poor manufacturability and high cure temperature (>177℃), damages tend to occur on other components. Heterogeneous repair, however, has better manufacturability and lower cure temperature, which can not only recover the properties of the damaged successfully but is suitable for rapid repair.

Key words: honeycomb sandwich structure, heterogeneous repair, mechanical property
