Strength properties of sandwich composite made from plywood as skins and corrugated paper board as core / Nur Atiqah Najib

The sandwich composite made from plywood as skins and corrugated paper board core were manufactured with different types of arrangement (vertical and horizontal) and different number of layer (single and double) by using the application of Polyvinyl Acetate (PVAc) resin. The objective of this study was to determine the strength properties of the sandwich panel by determining the (MOR, MOE and maximum compressive strength). The values of the (MOR, MOE and maximum compressive strength) were evaluated according to ASTM standard (ASTM C 393, ASTM C365). Based on the testing conducted the horizontal arrangement of corrugated core has highest MOR and MOE value. For the number of layer of corrugated core it was showed that the double layer gave higher MOR and MOE value. For the flatwise compressive strength it was stated that, the vertical of arrangement had higher maximum bending load while for the number layer it was indicates that the single layer can resist with higher maximum load moment. The bending strength properties (MOR and MOE) of the corrugated paper board were low, this materials does not fulfil the minimum requirements in most of furniture applications.
