“…The coconut shell has high lignin, which RESEARCH supports weather resistance, improves corrosion resistance and increases the strength of the material [6]. Due to its exceptional orientation of structure and low ash content, coconut shell is preferable to making the activated carbon black [7].…”

“…In the same way Nemli et al (2006) evaluated the mechanical and physical properties as well as the decay resistance of particleboards made from particles impregnated with Pinus brutia bark extractives. Interest has burgeoned in combining wood and other raw material into composite products that can utilize recycled materials (Youngquist et al, 1993a;1993b;1994). If it is known that bark has some advantages over wood when used as a mulch or in other soil amelioration approaches (Allison, 1965), it is not the same situation with its utilization in particleboards manufacture because of poor mechanical properties of those particleboards (Blanchet, 2000;Villeneuve, 2004).…”

Keywords:alkali treatment / mixed particleboards / outer bark of white birch / mechanical properties / physical properties Abstract • This study proposes substituting traditional raw materials in the surface layers of wood particleboards with the water resistant white birch (Betula papyrifera) outer bark particles, which can help improve the dimensional stability of manufactured mixed particleboards, thereby alleviating shortages of raw material in a cost-efficient manner.• Mixed particleboards were fabricated in the laboratory using untreated or alkali treated white birch outer bark particles as substitute material. These particles were resinated successively with three percentages of phenol-formaldehyde resin. Overall, the results of this study clearly demonstrate that the panels could be manufactured using up to 45% of the proposed substitute material and still maintain the required mechanical and physical properties.• Alkali treatment was used to remove natural wax from bark particles surface which hinders resin adhesion. This treatment negatively affected mechanical and physical properties of finished panels and the variation of phenol-formaldehyde resin percentage in the bark particles significantly affected only their hardness.• Panel with untreated bark particles in the surface layers, resinated with 5% phenol-formaldehyde resin was selected as the best with the help of a statistical analysis carried out in a factorial complete block design, especially from the dimensional stability criterion.

Ces particules ont été encollées successivement avec trois pourcentages de colle phénol-formaldéhyde. Les résultats de cette étude démontrent d'un bout à l'autre que les panneaux pourraient être fabriqués en utilisant jusqu'à 45 % de matière de substitution proposée et maintenir toujours les exigences des propriétés mécaniques et physiques.• Le traitement à la soude a été utilisé afin d'enlever la cire naturelle de la surface des écorces qui empêche l'adhésion de la colle. Ce traitement a affecté négativement les propriétés mécaniques et physiques des panneaux produits et la variation du pourcentage de la colle phénol-formaldé...

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 infi ltration from their surface. These panels were made up of outer white birch bark particles in the surface layers with coarse wood particles or wood fi bres 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 satisfying the indoor requirements for particleboards and those with wood fi bres in the core layer passed the requirement of medium fi bres 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.Keywords: Hydrophobic bark composite, mechanical and physical properties, mixed panels. RESUMENEl uso de la corteza externa de abeto blanco en la fabricación de canoas por las primeras naciones de Canadá es un ejemplo de su uso más antiguo. Esto confi rma sus características hidrófugas, la cual puede ser explotada mediante su uso en la superfi cie del panel compuesto de 3 capas para protegerlo de fi ltraciones de humedad. Estos tableros fueron fabricados con partículas de corteza externa en las capas superfi ciales, y con partículas gruesas o fi bras de madera en el corazón. Un experimento factorial en un diseño de bloque completo hizo posible realizar el diseño de experimento. Los dos grandes factores considerados, fueron el porcentaje de corteza en las capas superfi ciales con 3 niveles y el tipo de material usado en el corazón, con dos niveles respectivamente (partículas y fi bras de madera). Cuatro réplicas fueron hechas para cada panel. Sólo los tableros con partículas gruesas de madera en el corazón pasaron todas las pruebas físicas satisfaciendo los requerimientos del interior de los tableros de partí-culas. Paneles con 45% de partículas de corteza en la superfi cie y 55% de partículas de madera en el corazón fueron seleccionados como los mejores, debido a su buena estabilidad dimensional.
