Composites Joining

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...

With so many new materials available today for additive manufacturing (AM) production, how do you determine the best way to qualify your new feedstock? And is the AM method you want to use going to make a difference? These questions are discussed in Choices for Mechanical Testing for Qualification of Additive Manufacturing Processes, written by...

Metal matrix composites (MMCs) have always been considered “unweldable,” and have been joined mechanically in the past. Now, however, EWI reports that aluminum MMCs can be joined using friction stir welding, a solid-state joining method. This investigation is discussed in Friction Stir Welding of Metal Matrix Composites, written by EWI Senior Engineer Michael Eff. You...
