| contents | Physical and mechanical properties of panel based on outer bark particles of white birch: mixed panels with wood particles versus wood fibres Roger Pedieu Bernard Riedl André Pichette Agrociencias mixed panels Hydrophobic bark composite mechanical and physical properties The use of outer white birch bark in canoes is an example of its oldest use by the fi rst nations in Canada. This use confi rms the hydrophobic characteristics of this bark, which can be capitalized on by using it in the outer layers of three-layer mixed composite panels in order to protect them from water infiltration from their surface. These panels were made up of outer white birch bark particles in the surface layers with coarse wood particles or wood fibres in the core layer. A factorial experiment used in a complete block design permitted to carry a suitable statistical analysis of measured properties. The two main considered factors were respectively the bark percentages in the surface layers with three levels and the type of material used in the core with two levels. Four replicates were done for each panel. The panels with wood particles in the core layer gave physical and mechanical properties satisfyingthe indoor requirements for particleboards and those with wood fi bres in the core layer passed the requirement of medium fibres density board. Panel with 45% bark particles in the surface and 55% wood particles in the core was selected as the best because of its good dimensional stability. 2008 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48510303 en http://www.redalyc.org/revista.oa?id=485 Maderas.
