• Description:
  Recent small aircraft that have been certified in the United States, such as the Cirrus SR20 and the Lancair Columbia 300, share similar structural attributes. Specifically, they are both of nearly all-composite construction and both make extensive use of adhesive bonding as a primary method for forming structural joints. Adhesive bonding has potential for being a simple and cost-effective means by which large built-up structures can be assembled. Challenges to bonding exist in the areas regarding adhesive selection, proper surface preparation, and technician training as well as intelligent design and confidence in analyses. This report addresses the latter challenge by presenting an analysis methodology that can be used in the design of joints loaded in both tension and in-plane shear. Example calculations and applications to real structures are provided.
