SHEAR STRENGTH PERFORMANCE ANALYSIS OF HYBRID JOINTS (ADHESIVE AND RIVET) – SINGLE LAP JOINTS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
Adhesive bonded are already playing a significant role in the development and production of metal aircraft structures and indication are strong that such joints will be even greater importance in filamentary composite structures. The performance of a hybrid joint (adhesive and rivet) depends on many parameters and its design becomes complex when the design aims to create a synergy between these two joining methods which are commonly used to composite or different (various) metal plates. The design is applied to analyze the parameters that influence the load transfer between the different components of the joints as well as the maximum stress in adhesive. A first decomposition of the joint into functional requirements and design parameters leads to a coupled design. A decoupled design is obtained through the recording and reformation of both functional requirements and design parameters. The design matrix is then used to propose a new design through physical integration of the design parameters. Comparison between the new design and baseline geometry shows a reduction in the maximal stress concentration inside the joint. This improvement should result in higher load transfer capability while maintain similar dimensions. In various applications and also for joining various composite parts together, they are fastened together using adhesives or Mechanical fasteners or rivets.
