I had the pleasure of speaking to Paul this afternoon about my project and the use of carbon tubes / wrapping carbon tubes around foam core to make a strong space-frame and the shear amount of knowledge and information he gave me was astounding!! Several really good ideas and new takes and new techniques I hadn’t even considered. I’ve ordered materials from Easy composites in the past for glider and boat repair work and I’m really looking forward to working with Easy Composites on this project too! Thanks Paul!

@@easycompositestv I really appreciate the tests at the end. I've worked with and used carbon fiber in the automotive race industry (Renault spec racers) and years ago we used to make some components out of carbon fiber, but i never really got to see it tested like this! We all know it's strong but hard to visualize sometimes. We only used it for Naca ducts and some basic non-structural things.

[@snowleopard4689]

@@easycompositestv Before failure mode is achieved is the material in the elastic domain like steel would be before it reaches plastic deformation? Otherwise said, if the part is released from the machine after reaching 600kg at 10mm deflection would it still have the same dimensions as before being subjected to the test?

[@mattlang5194]

Haha yeah it's primitive in terms of test design, but the equipment is $10-20k and up. I've done the same type of test with static weights to the same effect, though. You don't need the fancy tensile tester, but you would need to build up a fixture for the test.

[@andyvan5692]

great video, PS: for the novices among us a mandrel ( not a mandrill- monkey family) is a rod of metal you mount between centres in a metal or wood lathe to hold a round part securely ie a pulley or donuts shaped object, the rod holds the part by the inner bore so machining can occur on the outer surface ( otherwise gripped by a chuck, held at a centre, etc.) as this is the only way to hold it and machine successfully.

Nice video, well explained without big egos for a change. If worst comes to worst, remember that common swimming pool acid will dissolve the aluminium tube away in a minute without affecting the CF at all. A professional fiberglass friend who makes fiberglass tubes, uses cardboard tubes, then just throws them in water overnight.

[@easycompositestv]

Interesting comment Mark; it wouldn’t be possible to use cardboard as a mandrel for a prepreg tube like this of course (the process relies on thermal expansion of the mandrel) but it’s a novel way of making a mastic fibreglass tube.

The interesting thing is not so much carbon fiber wich is strong, but the alternatives. Glass fiber, sandwich with carbon and glass fiber etc. For hobbyists this mean you can make things strong, if you have poor economy by mixing materials

[@TheJustinJ]

There is a benefit of using glass instead of carbon in certain tension applications where a little flex or shock absorbsion is desirable. Even carbon fiber aircraft such as sailplanes often use special high strength fiberglass in the wing spars instead of carbon.

[@bobdobalina1419]

Yes, agreed, more numbers would be good sometimes. They're not everyone's cup of tea so we don't tend to go too heavy into figures and calcs but we have at least a couple of videos in mind that will dive a lot deeper into material testing and comparisons. Stay tuned.

[@randallwatson391]

Great vid. Do you account for the thermal expansion of the aluminium mandrel when you consider what ID of the tube you want? I assume that the expansion of the mandrel "overrides" the contraction of the composite shrink tape. When calculating expected wall thickness do you assume that the consolidation will be more-or-less equal to that achievable using vacuum processes?

[@easycompositestv]

For size critical applications you would have to take into account expansion at the cure temperature of the pre-preg. The compression provided by the tape ends up being similar or slightly greater than a typical vacuum bag. However, the fabrics can only be compressed by so much.

For the intake part that's a great idea, but I would not recommend to proceed past the compressor.

Like including thermal expansion rates, the mechanical deflection of the compressor blades at full speed versus low speeds, the whole 9 yards.

Well, I think you’d also want to know the thickness too then! 1280g per m2 at 1mm thickness (or 1280kg/m3)

[@dontaskme9047]

That depends on the specific gravity of where it is being measured. It will weigh more on earth than on mars. Hope that helps.

[@ywen2174]

That changes depends on the amount of epoxy

[@adammtroutman]

Depends on the fiber, fabric construction, resin content percentage

[@MCBritta]

i know this is just a demonstration and most tubes will be mostly exposed to tension and bending, but one thing that's also good to know is that aligning the layers at a 45° angle greatly increases the tubes resistence against torque

[@easycompositestv]

That is correct and is often done specifically for tubes used under torque such as driveshafts etc.

[@thegreekgeek176]

Could you make a carbon tube with a wet lay or infused process instead of prepreg?

[@easycompositestv]

You could certainly wet lay in a very similar way to the repair done here and also similarly to a tube repair as seen in our Fishing Pole Repair Video. Infusion would be much harder in a practical sense for smaller tube sizes, although for bigger sizes it may work using a tubular bagging film and extra care to ensure the resin is evenly distributed all around the tube.

[@jjackson3240]

You can also make your own prepreg by doing a wet layup on flat carbon and then freezing it. Then when you are ready to make your tubing, just let the home made prepreg thaw just a bit and roll it on just like factory prepreg. It's much less messy that way and the carbon tends not to slip as much during application.

The overlap is only necessary to hold the fabrics together during the rolling process, so in this case the overlap was actually very small at around 3mm.

Thank you so much for the videos! I’ve learned a great deal watching your videos and really enjoy them. Is there a way you would suggest to add a raised “bead” to either end of a tube made in this fashion? Similar to the raised bead sections in the “complex carbon fiber tube” video. If I try and build an intake tube in this fashion I’d like to help insure that the boots would not blow off the tube.

[@easycompositestv]

Hi Jeff, yes, you could do this very simply. Just cut a long thin strip of prepreg and then wrap that round and round as each end of the tube, making the tube considerably thicker in a 'bulge' at either end. This way the tube would still be parallel on the inside (so would release from the mandrel) but you'd get the bead detail you want.

[@danieln1813]

How does this “homemade” tube compare to its off-the-shelf counterpart in terms of tolerances and resistance? (I'm talking about a tube with the same layup configuration and diameters)

[@easycompositestv]

Pretty similar Daniel because - although this is 'home made' as you say, the materials and manufacturing process are actually so similar. Maybe if we get chance we'll compare a tube made in this exact way with a matching tube from our stock range and put them both on the test machine. I'll wager that they'll be within a few percent.

Any tips on identifying the problem or checking the qualities before starting the process?

[@joshuaszeto]

this is really useful info! Can these tubes handle constant temperatures of 100c? I'm thinking like using tubes like these for long sections of radiator piping for automotive purposes. How stable is it if it were also in constant contact with things like antifreeze? And if the ends of the tubes were thick enough, can it be tapped or threaded? if so, would the difference in thermal expansion of steel hardware cause tolerance issues?

[@easycompositestv]

Hi Joshua, good question. So, because this tube was cured at 120°C the basic principle is that they would be OK for a service temperature of anything less than that (let's say 100°C to be on the safe-side). However, a couple of things would worry me about your application. One is the anti-freeze and the other is the continuous exposure to hot water. Although in the short term neither of these would be a huge problem, I think for permanent exposure to this environment a carbon fibre tube wouldn't really be suitable.

[@joshuaszeto]

@@easycompositestv is there any information on how much pressure something like a 3 inch cf tube can handle? like 30-40psi of air pressure is doable right? It most likely won't be sustained.

Do you pre heat the oven to get the aluminium tube to expand quicker before the epoxy starts to cure? Would you recommend against using a solid aluminium bar for this reason?

[@TomE1248]

Also, truly great videos. As inspiring as informative!

[@easycompositestv]

Hi Tom, good questions. The oven was already at temperature and yes, this helps to ensure that the aluminium expands before the epoxy cures. As for using a solid mandrel, yes, same principle. It definitely is possible to use a solid mandrel but - if you have one - a tube will warm up quicker and so would tend to be better for this process.

Yes, you could use a variety of methods to cool the tube and aid extraction, if you found it was necessary.

how to make a carbon fiber 1/4 inch thick part where you can attach it to an other metal part using screws?? I guess how many layers you need

[@HobiCerdas]

How much the weight

[@xavertheischinger97]

Thank you for this guys! Is it possible to make a such carbon fibre tube without preprag? (wet lamination) and how do I calculate the thickness of the tube?

[@easycompositestv]

It can be done wet lay in a similar fashion, albeit it is a lot more messy. Thickness is related to thickness of the cloth and number of layers used.
