MECHANICALLY-INDUCED WOOD WELDING

Antonio Pizzi, Milena Properzi, Jean-Michel Leban, Michela Zanetti, Frederic Pichelin

Abstract


Mechanically-induced vibration welding of flat wood surfaces and rotation welding of wood dowels, without any adhesives, gave strength values comparable to those obtained with adhesive bonded joints. The joints obtained have strength up to structural level but can only be used for interior joinery and furniture. The reasons of the welding effect are presented and explained both at the wood anatomical and molecular level

Key words : wood welding; wood fusion; bonding; adhesion; adhesives; lignin; joints; furniture; interface; composites.
