摘要/Abstract

摘要： 胶接连接应用日渐广泛,特别是在汽车和航空航天等结构领域。首先分析了复合材料/金属胶接连接方式的特点,重点介绍了接头中的次弯曲效应、异质材料间刚度与热膨胀系数的不匹配特性以及载荷传递特性。然后总结了提高胶接接头强度的研究进展,主要包括增大胶接长度和宽度、选择胶黏剂、表面处理、增加胶瘤和被粘合物形状的设计等方面。最后对胶接接头的发展趋势进行了展望。

Abstract: Adhesive bonding is one of the most appropriate method to connect two adherends in construction of composite structure. And adhesive bonded joints are used extensively in automotive and aerospace structures. Limited by the technology, composite materials can not fully replace metal, and the bonding between composite and metal becomes a critical problem. This paper analyses the characteristics of adhesive joints, including second bending, dissimilarity on stiffness and coefficient of thermal expansion between adherends and load transfer in joints. And then the methods are summarized on how to improve the mechanical strength of adhesive joints, including increasing the overlap length and width, choosing proper adhesive, surface treatment, designing of spew and adherends shape. At last, a brief prospect on the development trend of adhesive joints is proposed.

Key words: composites, metal, adhesive joints, mechanical performance, joint design
