Numerical and Experimental Investigation on Tensile Properties of Natural-Sand Reinforced Polypropylene

Reinforced polymer composites are replacing metals in many engineering fields due to their high strength to weight ratio, low cost, and resistance to corrosion. In this study, the tensile properties of natural-sand particle reinforced polypropylene composites obtained by means of numerical method we...
