ترجمة الملخص

In recent years Wood Plastic Composites (WPC) have found an increasing number of applications in markets. These composites have shown special interest in interior components for automotives such as seat frames, side panel and central consoles and construction industries, which includes siding, exterior decking and railing material.In this study Wood-based particles from two species: softwood (yellow pine) and hardwood (beech) were compounded into pellets at 15%, 30% and 45% by weight with virgin and recycled polypropylene and 2Wt% Abetiec Acid as coupling agent. Samples of WPC were fabricated by injection molding according to international standards.This study aims to investigate the effect of characteristics of both wood and polymer on the density, hardness and tensile properties of Wood-Plastic Composites. As well,short-term water absorption of samples was observed by immersing them in water at room temperature for several days to determine the effect of moisture absorption on the mechanical properties and the effect of virgin and recycled plastics on moisture absorption, too. The results indicated that increasing of wood flour content leads to increaseof the density, hardness and tensile modulus of composites. On the other hand, it decreases the tensile strength, elongation at break and elastic limit stress.Also,the density of WPC increased with increasing of immersion time. It seems that hardness values for all formulations did not affect by water uptake during water immersion.Regarding tensile properties, values differed according to formulations of samples and immersion time.
