Reminds me a good while back a lot of Quiznos Subs here in the US were going out of business and my old roommates and I almost bought one of their conveyor ovens 😆 It'd help to know how big and hot you need it to be! Are you looking for something like a reflow oven?

I don't think this would be the right application for this. It would probably trap moisture and bugs. Not to mention how you're going to cure it and protect it from UV long term. Why not just use lags/bolts? Are there any other solutions out there? This seems pretty non-standard. But then again, I haven't built a log cabin in a while 😄

Very cool! Do you have examples of the kind of synthetic fibers and thermal barriers you've made?

Hey @ricky914, welcome to Composites Community! Are your referring to the fog light surround?

Are you referring to where the two main beams join at the T?

Sorry for the delay. Looks like my response didn't get posted! Pictures would help us better understand what you're trying to do! I'm not quite sure this is our area, but definitely willing to help if we can 🙂

Hi @bgree, welcome to Composites Community! If you're making tubes chopped carbon fiber isn't the best choice due to the short random strands. A woven fabric where the strands interlock with each other would work much better. That said, you could use woven fabric as a base layer and chopped as an external cosmetic layer. Ideally, you'd want to find a chopped/forged prepreg if that's the look you want to go for. It exists but is very hard to find.

You're welcome! Definitely keep us posted! We'd love to get some updates and pictures if/when you're able 🙂

So long as you don't exceed Tg, you should be good. Do be aware of the exothermic reaction temp. Not just the autoclave temp. And definitely add some margin to ensure you don't exceed your limits. One thing you could do is insert a mandrel to hold the shape.

Hey @JT at Sequent, welcome to Composites Community! The spec you're referring to is the glass transition temperature - the point at which the resin begins to change from a solid to a liquid. Is there a reason you don't want to start with a thicker tube to begin with? Additionally, if you need high-heat capabilities there are other resin systems that can be utilized.

Are you wanting panels to DIY? Or a company to make it for you? And how many do you need? There are a couple of different ways to go depending on what you're looking for 🙂

For UK based product I'd try Easy Composites. Have you tried there?

Hi @sarah4ley How much do you need?

Hi @Jo Yawn RWC has it for $73.99/yd. If you don't need genuine Kevlar, you could go with generic Aramid Fabric from some place like Amazon. You might also be able to pick some up at a fabric store or commercial fabric place.

How large of a piece do you need? 🙂

Hey @Wiley, welcome to Composites Community! It sounds like you're looking for a sample of Kevlar/Aramid fabric. Is that correct?

Any chance there's some of this available @Emily Lewis?

Super cool @Jason Fairclough! I used to ride quite a bit 🙂 Are you planning on making parts for your car, bike, or both?

Hey Jason, What you're looking for is often called Tooling Board or Modeling Board. I believe you can epoxy some of this tooling board together if you can't find larger pieces elsewhere. @Emily Lewis at Rock West Composites may be able to help you out with sourcing some!

I have not! It looks like they're pretty close to me here in California though 🙂

I 3D print quite a bit! I've been wanting to incorporate carbon fiber into some of my prints for a while now. One thing I've been thinking about doing is adding in some carbon fiber stringers internally to the prints. I think the best way to do this is to make a void in the 3D model for the stringer, print up to the top layer of the void, add the stringer, and resume the print. I've also been wanting to try out carbon fiber infused filament, but I hear it's rather rough on nozzles. Have you tried any of the CF filaments yet?

Something I've been thinking about adding is an overview section, maybe even a couple of videos. Is this something you and @jenn4536would be interested in?

Welcome @Dave K.! Great to have you onboard. Did you start out in aerospace or did you work your way into it?

Absolutely! Between composites and 3D printing, there is so much to leverage. Many things that used to be impossible, near-impossible, or extremely difficult can now be achieved in hours. It's pretty nuts! I'm really excited to see the kinds of vehicles that will come out over the next decade thanks to this technology! Who knows what's gone into the B-21 Raider, for example, but I'd bet it's just the tip of the iceberg that we'll see over the next few decades as these materials evolve.

Easy Composites has a YouTube channel with some pretty great tutorials on various carbon fiber techniques and processes. The link to their YouTube channel is https://www.youtube.com/channel/UC7F-suscQATns3qRYHpyijw
