EFFECTS OF FRICTION STIR WELDING ON POLYMER MICROSTRUCTURE

摘要

Friction Stir Welding (FSW) technology has shown great promise as a method of joining polymeric materials. Welds in several materials have achieved over 90% of base material tensile properties. Flexural strength has reached 90% of base material properties in PP. Research has shown a correlation between the process weld microstructure and mechanical properties. A study currently being performed establishes the relationships between the process parameters, material microstructure, and mechanical properties.
