Examination of Pull-out Test: Response of Sandwich Panels with Different Core Materials – Part 2

Examination of Pull-out Test: Response of Sandwich Panels with Different Core Materials – Part 2

In our previous article, we delved into the exciting collaborative project between the Concordia Centre for Composites (CONCOM) and Innovative Composite Products (ICP). Our mission was to put various panels to the test using galvanized flanged hex head screws provided by ICP in a screw pull-out evaluation.

To ensure consistency in our testing conditions and to establish consistent boundary conditions , we introduced a stainless steel circular plate. This plate had an inner diameter of 3.125 inches, an outer diameter of 5.5 inches, and a thickness of 0.3 inches.

We prepared a total of 18 unique samples, each combining different core and sandwich panel configurations. In our initial round of tests, we didn’t use the specified boundary condition. Instead, we secured the sandwich panels to a lower bed through clamping. It’s worth noting that this setup had its limitations – it only allowed us to screw half of the screw length into the sandwich panels.

Now, as we move forward, we’re excited to present and analyze the results of these experiments in a series of three separate articles. Part 2 of this experiment will focus specifically on the results of the pull-out tests conducted on the composite sandwich panels.
