In the most recent EWI Insights, there is an article highlighting a recent Friction Stir Welding (FSW) study with Polypropylene with nanocaly filler. This welding study showed that superior weld joints could be obtained in thick section thermoplastic composites. The weld strengths obtained for 6 wt% nanocomposite were significantly higher than those found during other polypropylene nanocomposite welding studies using alternative methods.
