  1. @Joshua Lyon will hopefully have the information that you need πŸ™‚
  2. Hi @Harsha, I can ask the folks at RWC and see what thermocouples they use for their autoclave. Not sure if they are the same ones, but I'll let you know! I did a bit of research, and this seems to be a common problem. The one thing that was recommended was the be extra careful with the wires, and some people mentioned adding cord protectors to limit the bending. What kind of thermocouples are you using right now?
  3. Hey again @Brennan, I checked with the RWC team, and they say it should have identical properties as 14046-D | 0.006" Thick Unidirectional Carbon Fiber Prepreg β”‚ Rock West Composites.
  4. I'd recommend buying a Carbon Fiber Sheet and cutting and drilling it to your desired shape πŸ™‚
  5. Sorry about that! Wrong link. @Emily Lewis, is this something that you have any information on?
  6. Hey @Brennan, There is some information available in the product webpage if you scroll on down. Is this what you're looking for?
  7. You definitely could! Just keep in mind this wouldn't be field serviceable, and if you're out at an event you probably want that. Just make sure you weigh your pros and cons carefully. As for the epoxy, 3M Scotch-Weld Epoxy Adhesive DP420 is a good one. I've got a friend that might be able to chime in who does a lot of bonding. I'll see if he can pop in and give you some advice πŸ™‚
  8. Missed this one! @John Kimball or someone else might have some input πŸ˜€
  9. The concern here would be the tube getting hit by rocks and debris. Most off-road vehicles continue to use steel for this reason. Off-road cars also tend to see consistent speeds where you won't see as much long-term benefit through the race from carbon fiber. A lot of the benefit in carbon fiber driveshafts come from reducing weight so the engine doesn't have to overcome as much inertia during acceleration.
  10. Hi @christiaan , Which SKU are you referring to? πŸ™‚
  11. Certainly doable! Rock West Composites already sells a lot of carbon fiber tubes for driveshaft purposes. What kind of racing are you doing? Any pics of your car?
  12. Hi @casey, I'm not sure on this. We've had a few people ask about repairing composites and though it can be done, I'm not sure that it will put up with the force I'd imagine you're going to put it through. We've had other people ask about repairing things like composite bats and bike frames, and the general consensus seems to be that it needs to be replaced. That said, if you're willing to invest the time and materials I found some videos below that might be helpful:
  13. I mean literally use a tough outdoor fabric like Sunbrella for the sides and aluminum for the floor. Sunbrella is the kind of fabric they use for outdoor furniture cushions. That kind of fabric goes by lots of other names, but that's the brand name I've used before. This would keep the weight down to a minimum, fit all of the curves of your trailer, and it's UV resistant to boot. You can attach it with grommets and elastic rope to loops on the frame or something of the sort. Or use grommets and rivet it directly to the frame but I don't think that'd provide the fit you're looking to accomplish. Then for the floor you can use carbon fiber or aluminum. Anyways... there are a lot of ways to go about this, but that's how I'd do it πŸ™‚
  14. You can use carbon fiber sheets but the bends are going to be a challenge. So is UV damage. The carbon fiber is likely going to get brittle and splinter over time. Why don’t you just use fabric?

    Layup material

    The layers and carbon fiber fabric choice depend a lot on how lightweight you need it to be and what your budget is. A lot of people go with carbon fiber for a top layer and use fiberglass underneath. Some use full carbon. As you mentioned, there are also different material choices. There are a lot of great videos showing how to do this on YouTube. The only I’ve noticed is that most of them don’t show how to make the support structure.
