Producing Value-Added Composite Panels from Aspen Slash Wood

Typical aspen slash wood (left) and flakes (right) sliced from the slash wood. Steve Schmieding, Forest ServiceSnapshot : The disposal of forest thinning residue is a concern when looking at sustainable forest management. Researchers found this material could be a valuable resource for commercially available structural panel products.

Summary

The disposal of forest thinning residue is a concern when looking at sustainable forest management. FPL researchers investigated the technical possibility of utilizing aspen logging slash wood with diameters ranging from 50-76 mm for flakeboard production. Influences of weight ratio between slash wood and commercial flakes on the selected mechanical and physical properties of panels were examined, as was the need for extra debarking process for panel fabrication. The results indicated the modulus of elasticity, modulus of rupture, internal bonding, linear expansion, thickness swelling and water adsorption of flakeboard made from aspen slash wood flakes were all comparable to those properties of panels made from aspen commercial flakes. The results indicated abundant slash wood, which was normally characterized by inferior mechanical and physical properties, could be a valuable resource for commercially available structural panel products.
