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...

Low force friction welding, a hybrid technology developed by EWI and MTI, uses an external energy source to raise the interface temperature of the parts being welded, reducing process forces required to make a solid-state weld compared to traditional friction welding. Low Force Friction Welding of Bimetallics: Aluminum 6061 to 1020 Steel Tubes, written by...

Continuous fiber reinforced thermoplastic composites (CFRTPCs) are increasingly being used in aerospace, automotive, and oil & gas (O&G) due to their low cost, recyclability, complex shape adaptability, high strength, and low weight. The CFRTPC market worldwide is projected to grow by US$634.1 million, driven by a compounded growth of 8.3%. Continuous Carbon Fiber displays the potential...
