Composites Joining

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...

Michael Eff, EWI Congratulations to EWI Principal Engineer Michael Eff who has won (along with colleagues Logan Smith and Ian Donaldson) the 2022 Howard I. Sanderow Outstanding Technical Paper Award from The Metal Powder Industries Federation. The paper, Joining of Two-Piece Aluminum Metal Matrix Composite (Al-MMC) Transmission Carrier Via Friction Stir Welding, was selected from...
