“…Since the wood of the Moroccan maritime pine is rich at the national level, and needs to be regenerated at the age of maturation, and since this wood has no relevant application on an industrial scale, and that the current world production of plastic is around 100 million tonnes per year [4], which threatens the ecosystems of our planet, it is expected to value them in composite materials called wood-plastic composites (WPC), these composites represent an emerging class of materials that have gained increasing degrees of acceptance because of their favorable performance characteristics such as improved stiffness, density, lower abrasiveness, better processing capacity, favorable cost of wood and plastic and a significant reduction in environmental impact [5][6][7][8][9]. The field of application of (WPC) is diverse; it is used in furniture, floor covering, on walls and ceilings, stair treads, sliding doors, bulletin boards and other Industrial Products [10][11][12][13].…”
