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...

Cold spray is one of the fastest metal additive manufacturing (AM) production techniques in the world. It offers an effective method for applying unique coatings and making repairs with similar or dissimilar metals. It eliminates heat affected zones and can be used on heat sensitive materials. It is an environmentally friendly process, particularly when compared...

Continuous fiber reinforced thermoplastic composites (CFRTPCs) are strong, light, inexpensive, recyclable, and easy to shape. These attributes make CFRTPCs highly attractive for manufacturing use in the aerospace, automotive, and energy industries. EWI associates Jeff Ellis, Miranda Marcus, and Matt Nitsch have recently validated through-transmission laser welding (TTLW) as an effective joining method for thermoplastic composites....
