Abstract
In this study, the effect of adhesive on the flexural properties of stressed skin components (SSCs) with a gap-filling phenol resorcinol adhesive (GPRF) was investigated. For this purpose, SSCs that were manufactured using different fastening methods (press-gluing, screw-gluing, screw-only and no-connection) from Douglas fir plywood skin and spruce-pine-fir lumber stringer were tested at two-point loading in bending. The experimental results showed that the introduction of the adhesive makes stressed skin panels much stronger than conventional screwed-only components. The study determined that the modulus of rupture and slope of load-deflection curve were increased with addition of the adhesive. The results showed that the required strength could be achieved using press-gluing as well as screw-gluing fastening methods. Also, the methods may be used for the sound and economical interior and exterior applications i.e. panel based building components manufacturing.
