Composites Joining

At EWI, our focus has always been on helping manufacturers solve real problems and move advanced technologies from concept to production. In 2025, that mission translated into meaningful progress across research, technology development, and knowledge sharing to support industries navigating increasingly complex technical and economic challenges. Throughout the year, our teams worked closely with partners...

Developing reliable ultrasonic welding parameters for polymer joining traditionally involves a time-consuming and costly trial-and-error process. For many companies, this leads to wasted materials, labor, and resources, particularly when validating welds through expensive fatigue testing. But what if you could predict welding parameters using standard material properties, before any physical testing even begins?  In Prediction...

Using polymer pipelines safely and reliably in an energy transmission network requires a solid understanding of how the materials will be affected when exposed to CO2 at a range of different processing conditions. What happens when CO2 pressure, temperature, and mechanical loading – or all three – shift in the field? What kind of material...
