A study of single lap joints of composite materials with and without attachments is presented. Failure of this type of joint is caused by the high peel stress in a perpendicular direction presented in the geometric singularity. It is shown that the joint strength is affected by factors such as surface preparation, the adhesive curing process and cleaning. The two configurations, with and without attachments, are compared. It is shown that the single lap joint with attachment has a higher strength than the joint without attachments when no fillet is left on the geometrical singularity. However, because of the low increase in joint strength and the complexity of manufacturing, the choice of type of joint is left to the manufacturer's judgment.
