摘要: 本文以航空发动机复合材料风扇叶片钛合金加强边胶接为研究背景,开展钛合金/复合材料胶接技术研究,着重研究了基于AF191胶膜的钛合金/复合材料胶接工艺参数、不同结构复合材料与钛合金以及不同表面处理方式钛合金与复合材料胶接强度。结果显示:采用热压罐固化,并且在加压0.1 MPa后卸掉真空更有助于胶接;不同结构复合材料对胶接强度影响较大,刚度更高的复合材料表现为更好的胶接强度;采用酸洗和阳极化处理钛合金表面均能大幅提高胶接强度,并且配合表面预处理剂使用更佳。

Abstract: In this paper, the study on bonding technology of titanium alloy/composite material was carried out based on the background of bonding between titanium alloy trim and composite fan blades of aeroengine. The study focused on the bonding process parameters of titanium alloy/composite based on AF191 film, the bonding strength of composites with different structures/titanium alloys and the different surface treatment methods of titanium alloys/ composites. The results show that: Curing by autoclave, and removing the vacuum after pressurizing 0.1 MPa was more helpful for bonding. Composites with different structures have a greater impact on bonding strength, and composites with higher stiffness show better bonding strength. Pickling and anodizing the titanium alloy surface can greatly improve the bonding strength, and it is better to use with the surface pretreatment agent.

Key words: bonding, titanium alloy/composite, surface treatment, woven structure, laminated structure
