With the increased use of adhesives in industrial applications, there is a need to consider not only strength and stiffness, but also how bonded joints will perform in the long term. In aerospace and automotive applications, this means at least 10 years. In buildings and civil engineering structures, much greater timescales are needed. All classes of bond are important whether they be structural or for ‘less important’ applications such as trim, sound deadening. Vehicles which become ‘shabby’ with trim beginning to detach may not lead to warranty claims, but can easily cause loss of reputation. The objective of this paper is to illustrate some of the traps into which a designer might fall and how to avoid them. For a given configuration and expected set of loads, this involves correct choice of the adhesive, specification of the surfaces and some means of checking consistency of the adhesives on delivery to the client, together with the processes used in production.

随着工业应用中粘合剂使用的增加，不仅需要考虑强度和刚度，还需要考虑粘合接头的长期性能。在航空航天和汽车应用中，这意味着至少 10 年。在建筑物和土木工程结构中，需要更大的时间尺度。所有类型的粘合都很重要，无论它们是结构性的还是“不太重要”的应用，例如装饰、消音。车辆变得“破旧”并开始脱落可能不会导致保修索赔，但很容易造成声誉损失。本文的目的是说明设计师可能落入的一些陷阱以及如何避免它们。对于给定的配置和预期的一组负载，这涉及正确选择粘合剂，
