摘要: 为了研究不同体系胶黏剂对碳纤维复合材料基材的粘接性能,采用环氧树脂、丙烯酸酯、聚氨酯三种体系构成的7款不同的胶黏剂对碳纤维复合材料-碳纤维复合材料(CF-CF)进行胶接,并分别将其放置于室温和极限温度(80 ℃、-65 ℃)下进行拉伸剪切强度测试,以探究每种胶黏剂的力学性能和破坏模式,并将环氧胶黏剂在室温下对不同纤维类型的复合材料(T700-12K碳纤维复合材料、T300-3K碳纤维复合材料和玻纤复合材料)进行胶接性能测试,探讨碳纤维和玻璃纤维复合材料的粘接机理,进而选出性能最优的胶黏剂,为航空航天与汽车等领域中碳纤维基材之间胶黏剂的选择提供借鉴。

Abstract: In order to study the bonding properties of different structural adhesives on carbon fiber composite substrates, seven different structural adhesives composed of epoxy resin, acrylate and polyurethane were used to bond carbon fiber composite-carbon fiber composite (CF-CF), and the tensile and shear strength were tested at room temperature and ultimate temperatures (80 ℃, -65 ℃). In order to explore the mechanical properties and failure modes of each adhesive, and test the bonding properties of epoxy structural adhesive to different fiber types of composites (T700-12K carbon fiber composite, T300-3K carbon fiber composite and glass fiber composite) at room temperature. The bonding mechanisms of carbon fiber and glass fiber composite are explored and then the adhesive with the best performance is obtained. It provides a reference for the selection of bonding agent between carbon fiber substrates in the fields of aerospace and automobile.
