Resumen
APPRAISING AND PROTECTING FORESTS REQUIRES A MANAGEMENT PLAN AND THE CREATION OF INNOVATIVE PRODUCTS FOR THE MARKET. THE DEVELOPMENT OF THE GREEN GLUING TECHNIQUE COULD ADD VALUE TO NATIVE TIMBER. HOWEVER, THERE IS A LACK OF KNOWLEDGE CONCERNING THE RESPONSE AND THE PRODUCTIVE PROCESS OF NOTHOFAGUS SPECIES USING THIS TECHNIQUE. THIS WORK INVESTIGATED THE VIABILITY OF IMPLEMENTING THE GREEN GLUING METHOD USING THREE TYPES OF NOTHOFAGUS. WOOD PIECES WERE MADE USING A ONE-COMPONENT POLYURETHANE ADHESIVE. DELAMINATION, SHEAR TESTS, MORPHOLOGICAL CHARACTERIZATION, AND BOND LINE THICKNESS ANALYSIS TESTED THEIR CAPACITY. THE RESULTS SHOWED A VARIABLE RESPONSE DEPENDING ON THE NOTHOFAGUS TYPE, WHERE THE SURFACE TREATMENT COULD IMPROVE THE GREEN GLUING PERFORMANCE. THE FINDINGS HIGHLIGHT THE RELEVANCE OF INCREASING KNOWLEDGE ABOUT THE ESSAYED SPECIES AND THEIR PREPARATION TO MAINTAIN THEIR NATURAL MOISTURE CONDITION.
