Abstract
Recently, carbon fiber reinforced plastic (CFRP) material has been used in structural element of transport vehicles. Besides, adhesive bonding is known as better method for joining the CFRP structures The purpose of our work was to examine the characteristics of strength for CFRP composite structures. We modeled single-lap adhesive joints composed of quasi-isotropic CFRP laminates having various lay-up pattern subjected to static tensile load to carry out finite element method analysis, and compared the analysis results of stress distribution at adhesive layer. In addition, failure load of various adhesive joint specimens were measured. As a result, it was found that the stress distributions on adhesive layer and failure load for joints were affected by each lay-up patterns of CFRP adherends.
