Valorization and Characterization of Maritime Pine (Pinus pinaster) Wood from the Maamora Forest in Plywood Panels

Abstract: Morocco has undertaken reforestation, since, the 1960=s to meet its needs for timber. Among these species, there are softwood in general and especially the Maritime pine (Pinus pinaster) because of its rapid growth, its relatively short life span and its strong rooting. The physical and mechanical study of 4 trees of the reforested Maritime pine (Pinus pinaster) from the Maamora forest (Machraa El Kettane) in Morocco at maturation age showed that according to the Growth Constraint Indicators (GCI) of the four trees, the Maritime pine wood is quite nervous with an average stress of about 75 μdef. The sawing performance of the resulting plots is close to 58%, the flows have medium quality, the artificial drying of the planks with a moisture content of 54% lasted 165 h. As a result, the final humidity is 10%. The physical and mechanical characteristics allowed to classify this wood in moderately nervous, semi-heavy and soft wood and usable as ground-wood or in sawn-wood for the manufacture of boxes and carpentry. The wood of the Maritime pine (Pinus pinaster) from the Maamora forest (Machraa El Kettane) was subject to transformation into plywood panels. These panels were made in three folds that have a density variation between 520 and 550 at 12% moisture, a medium flexural strength of 24 MPa, an average compressive strength of 25 MPa and a rolling shear that varies between 2.1 and 2.6 MPa. These plywood panels of Maritime pine can be classified as panels with medium density and high rigidity.
