Abstract

Methods of joining composite sandwich panels together using adhesive bonding were reviewed. The tongue and slot joint was chosen for the basis of this investigation associated with the box structures used in aircraft galleys. The important load carrying characteristics of sandwich panel were defined and the problems involved in transfering load from one panel to another were identified. Joint designs to alleviate these problems were obtained initially by experimental work and an evolving process of reinforcing the joints locally to eliminate failures up to the design loads required for current galley structures.

These joints were then investigated by finite element stress analysis with the object of predicting their static strength for the purpose of including this analysis in future design methods so reducing the experimental requirement. Material static testing was carried out to obtain strength and stiffness to insert in this analysis.

The predictions were largely successful when compared to the test results indicating that the analysis could be used in the design of such joints. The joint designs represented a useful weight and cost savings over previous methods of joining the panels together.
