Popis: In almost every industry, polymer materials are in high demand in recent years due to their lightweight and easy formability. However, eco-friendly, cost-efficient and defect-free joining of polymers is a major concern. In this article, a novel approach is taken for friction stir welding of polypropylene by implementing a double-side welding technique. The effect of tool rotational speed on construction and properties of the welded joints are studied. The torque and forces exerted on the tool during double-side welding are compared with single-side welding. Cross-sectional morphology examination using optical and scanning electron microscope reveals defect-free sound welding by double-side weld with uniform material flow. The molecular bonds of the welded specimens are examined by FTIR analysis. The double-side welding technique yields superior joints in terms of tensile strength and flexural strength than the joints obtained by single-side welding.
