Resumen:
Nothofagus pumilio and N. antarctica forests of Southern Patagonia, Argentina are currently beingmanaged for production of saw logs with fast growing conditions. The result of these managementstrategies is faster growing forests, but also an increase in the percentage of low-density wood. Themotivation for this study was to find a way to valorise this low-density wood. Surface and bulkdensification treatments were applied these wood species and were then applied as face layers inthree-layer composites. The mechanical properties of three-layer composites were studied. Themodulus of elasticity, modulus of rupture, and modulus of hardness were improved compared tomany types of structural composite lumber. This increase in mechanical properties of N. pumilioand N. antarctica wood opens the possibility for its use in structural composites and added value tothese otherwise underutilised and undervalued species.
