The design of bonded joints must take into account the nature and magnitude of the likely operating stresses and strains, and should be contrived so that unacceptable peel or cleavage forces are not introduced into the bondline. Such design should also allow for changes in the mechanical properties of adhesives which may take place under different operating environments. As with all joints, they should also be designed for ease of location and assembly, and consideration should be given at the design stage to the means of clamping or holding of the component parts whilst the adhesive cures. The control of bondline thickness may also be achieved by making components self-locating or by the introduction of ‘designed — in’ spacers. Small changes to a joint’s design may help very significantly in ensuring location and speed of fabrication, as well as with quality of the finished assembly.

As a further quality check from strength tests, it may be possible to design joints from which test coupons could be removed periodically for assessment.
