Staple Holding Strength of Furniture Frame Joints Constructed of Plywood and Solid Wood

The withdrawal and lateral holding properties of three types plywood with one stapled as well one-row multi-stapled joints were studied compared. results show that variations in density have a significant effect on strength relatively small strength. At four staples, the eucalyptus 0.59 g/cm3 is 1821 N, which 21% higher than poplar 0.51 at 1498 N 32% eucalyptus/poplar composite 0.53 1275 N. In terms strength, has 1603 12% lower 1807 10% 1761 plywood. As number staples increased from 1 to 4 increments 1, continued increase, while nodal strengths did not differ significantly between 3 there increase for all nodes. Equations predicting derived separately.
