Testing And Evaluation Of A Slot And Tab Construction Technique For Light-Weight Wood-Fiber-Based Structural Panels Under Bending

This paper presented construction and strain distributions for light-weight wood-fiber-based structural panels with tri-grid core made from phenolic impregnated laminated paper composites under bending. A new fastening configuration of slots in the faces and tabs on the core was applied to the face/core interfaces of the sandwich panel in addition to epoxy resin. Both normal strain gages and shear strain gages were attached on these panels to analyze inside strain distributions by third point load bending test. The purpose of the bending test was to investigate the various strain distributions of panels with different face/ core configurations that identified the critical failure modes for future design. In this research, four panels with…
