Examination of Pull-out Test: Response of Sandwich Panels with Different Core Materials – Part 3
In our preceding publication, we explored the dynamic collaborative research initiative conducted by the Concordia Centre for Composites (CONCOM) and Innovative Composite Products (ICP). This study was dedicated to examining the pull-out responses within sandwich panels, specifically those incorporating Glass/PP composite facesheets, diverse core materials, and drywall. By implementing a circular boundary condition fixture, the investigation emphasized the pivotal roles played by core material, core thickness, and engaged facesheets in determining pull-out behavior. Notably, the PET foam core material with a 50mm thickness demonstrated the highest pull-out values, while the number of engaged facesheets emerged as a significant influencer of the pull-out force.
Furthermore, the research shed light on the importance of material thickness and engaged facesheet quantities, highlighting the necessity of normalizing results against the effective screw length for precise evaluations. The study also underscored the notable impacts of boundary conditions on pull-out test outcomes, revealing the intricate interplay between core materials, effective screw length, and boundary conditions.
