How Strong is Forged Carbon Fibre? Forged Carbon vs Aluminium vs Markforged vs Onyx

Further information and links ▼

In this composites video tutorial we take a look at the mechanical properties of 'forged' carbon fibre components, made using randomly oriented short-strand carbon fibre, and compare them to the strength of cast aluminium, 3D printed Onyx and Markforged 3D printed carbon fibre.

We run a series of basic mechanical tests to compare their tensile strength and stiffness and then perform a 'real word' test based on a bending load on a brake lever component made from these different materials.

Honestly, you are doing amazing work here. I'd never expect such a level of scientific method from a "company" channel.

As a biker and fan of making CF items, I am extremely impressed by a diy built forged carbon fibre lever. Add the aligned strands and wow. That's borderline autoclave professional CF.

This is brilliant guys, thank you very much for the efforts that you put in these great free engineering lesons

[neetones]

This is an absolute master class in how to present data, compare results, and teach. Every single thing you mentioned is perfectly clear and supports learning. You are an excellent teacher.

[RamyRC]

Very interesting results, I did try your forged carbon fiber mothed the other day and turned out great!
Thank you very much for making these videos, keep them coming please.

Wow this is out of my realm of use but just wanted to comment on how visually appealing your test setup with real time measurements is. Absolutely top shelf.

[Runmeerkat]

After hearing about forged carbon fiber for the first time this has always been on my mind. Thanks for the video it will be interesting for sure.

I love you guys for not only showing such a wide range of fabrication and composition techniques and making them so accessible and easy to understand, but also for the honesty and science involved in your analyses and the matter-of-factness about which techniques are well-suited for the various possible designs.

[BMSWEB]

Not only absolutely mind blowing data! but so well presented!!! Thank you

[lsgt]

Great video, this has been highly anticipated since watching the process of making the forged lever. Thanks for the data driven approach as well as the real world explanations!

[jxxd]

Wow Paul. You just won the internet. This is hands down the best video on this topic I have ever seen. I am now a total convert and looking forward to being your customer. Also inspirational stuff for making clips for our own business when we market our planned products using these manufacturing methods. Thanks so much.

That’s pretty impressive just how strong that forged carbon fibre can be, plus the advantage of weight saving makes it a great choice for many applications. Thanks for this great video.

[Thomason]

the level of scientific testing shown here is insane for a youtube video, like this is solid research.

[sheldon...]

Great video, you did a really good job of demonstrating and explaining the differences between the different methods. I particularly liked the playing card analogy.
Can't wait for the next one 👍

I bought your development kit and have been printing molds and making parts successfully. Absolutely love this process and your dev kit was the perfect package.

Paul and Matthew, you guys are absolute legends. That you for such an amazing offering. Everything you guys do is awesome

[ddegn]

That *Optimized Forged CF* is really impressive. Is the method to make this sort of part as straightforward as you suggest in the video? I really like your forged DF videos (OK I like all your videos) but I don't recall seeing a video about making an optimized forged CF part. It would be great to see any tricks you have to share.
Thanks for another really interesting video.

[Coulter.Machining]

fantastic video! very easy to understand and interesting results! I just made my first Forged Carbon part the other day thanks to your prior video and I am loving it!

[andresilva]

I only found out about forget carbon fibre in your last video, now I want everything in my life to be forget carbon fibre and reinforced when needed. What an amazing video. Thank you!

[eddie]

I bought the forged carbon starter kit because I saw your last video. Got my first part done yesterday. It turned out amazing. Thanks for those informative videos. Please keep it up👏🏼
