3D Printed Preforms Improve Strength of Composite Brackets | The Cool Parts Show Bonus

- Continuous fiber composites offer good mechanical properties, but can be difficult to apply in exactly the right configuration. Chopped fiber reinforced materials are easier to work with, but the shorter, randomly aligned fibers don’t provide equivalent strength. 9T Labs uses an unusual manufacturing strategy to achieve the best of both worlds: 3D printed continuous fiber preforms that reinforce a compression molded part otherwise formed from bulk molding compound including chopped fibers. In this bonus episode of The Cool Parts Show, we look at a pin bracket for the overhead bin of an airplane developed by 9T Labs and Purdue University. Two different versions- one with and one without the continuous fiber preforms - were created and tested, and we share the results.

That's a really cool confluence of rapid manufacturing techniques.
Super cool. I love the aesthetic of composits, and this made me love this material even more.
We like composites, too, and cover them regularly in other videos and articles: www.additivemanufacturing.media/hashtag/composites
Thanks for watching!
This won't highlight the aesthetic aspect, but Pete also talked composites with Jeff Sloan, editor of CompositesWorld, on the AM Radio podcast: www.additivemanufacturing.media/articles/additive-for-composites-and-composites-for-additive (You can give it a listen or skim the transcript.)
I simply just love the show. Good job !
We appreciate it! Thanks from the entire The Cool Parts Show and Additive Manufacturing Media team.
Amazing ⭐️⭐️⭐️⭐️⭐️⭐️⭐️
