    You guys deserve all the success you get; these videos are some of the best marketing I've ever seen (and I've been in the business for decades).
    You're not simply selling a product. You're putting genuine effort into releasing detailed, helpful, well written, and well presented content that's available to everybody, not just your customers. You continue to demonstrate a sincere commitment to helping people improve themselves and their projects, and very few companies can say that. I know that there's a hell of a lot of work that goes into these videos, but to my mind, it's the perfect marketing tool for your particular product.

    Slight correction, stainless steel has the same Young's modulus as mild steel. In fact, almost all types of steel have Young's moduli of 200±10 GPa. Heat treatment does not change this either.

      Thanks for the comment and apologies for the error. You're quite right and in fact the original script just noted that stainless steel is considerably stronger (not stiffer) than mild steel. We're normally pretty good at spotting such mistakes but this one got through about 4 proof watches by several people so maybe we need to tighten our procedures! I think I've been able to do a rough-and-ready 'trim' on the video (which RUclips allows, until the video has had 100,000 views) so you'll soon see the line slightly clumsily removed.

    You could redo these tests while using an 8mm bar as filler in each end to give a solid grip on each tube reducing the stress risers at the collet. This would focus the test to just the tube section between each collet and provide sufficient grip without crushing

    • @easycompositestv
      @easycompositestv  Год назад

      Your question is one that we get asked quite a lot an unfortunately there isn’t a simple answer to it. When we make carbon fibre parts ourselves we often wrestle with how we can make replacement parts attach in the same way as the original ones. The solution is often different every time and sometimes involves salvaging some of the clip or bracket off the original part (if it is to be discarded) or making something similar to the original bracket any way we can (by fashioning it out of a bit of plastic angle for example) or sometimes even making a small carbon fibre bracket and bonding it to the reverse of the original part. A ‘captive nut’ can sometimes be laminated into the part so that it can be screwed into.
      In short, there’s no one solution for all. You just need to see what you’ve got and do whatever works best each time. Almost always you’ll make the part without the brackets or fixings and then add them on after. You can bond using a little of the epoxy resin, a polyurethane resin or something like Araldite.

    Hi, great video. Perhaps you could give the dimensions of the double bend rig so those of us interested can work out the bending moments and Si units.
    Something on joining tubes (eg how much fibre wrapping etc) would be nice.

    • @easycompositestv
      @easycompositestv  Год назад +4

      Because the tests weren't done to any proper standards, we'd be a bit wary of anyone using the results to derive performance data on the tubes. For example, the 3D printed saddles on the 3-point bend test compress quite a bit. Whilst it's still a fair comparison between the different tubes, this would cause inaccurate data on the stiffness of the tubes per-se. Noted on some more joining information; this is something we'll have a think about : )

    • @easycompositestv
      @easycompositestv  Год назад +1

      That could be a topic for a future video yes. It's generally a case of bonding inserts into, or onto, the carbon fibre tube and then linking the inserts. Composite joining sections are an option but are very expensive (due to the huge complexity involved in making them). As rtz points out, you can also bond smaller or larger tubes inside or outside of the main tube to sleeve or ferrule them where you need additional strength.

    Very cool to watch. I was waiting for a mention of fishing rods. Carbon fibre has revolutionised them. Using a carbon fibre (I assume they’re carbon fibre) rods is a complete shock to the system, how can this ultra stiff rod cast like my old fibre glass rod. It doesn’t take long to get used to casting and loading up the rod with energy to let it fire my lure way further than the old glass rod. Lightweight and strong, stiff too but easy to cast long distances.

    • @easycompositestv
      @easycompositestv  Год назад

      Quite right! Another great application for carbon fibre. I think where it’s a fishing *rod* then it will be carbon fibre rod (solid), when it’s a fishing pole then it will be a carbon fibre tube.

      Of course Tony, that's really where it all starts to make sense.

    Porsche have upgraded CF anti-roll bars for the GT2RS and for 1 of my cars, reducing weight at the very front of the car (reducing the ARB's polar moment of inertia within the car) with a CF anti-roll bar, certainly the torsion bar section, would be a nice improvement.

    • @easycompositestv
      @easycompositestv  11 месяцев назад +1

      ARB's prevent twist so it is likely to be some kind of spiral orientated fibres or lay up to resist twist. I suspect there has been extensive testing and prototyping to work out what is the best layup.

    I see a lot of CF videos where the product comes out sort of floppy, and I thought CF was supposed to be really rigid.

    • @easycompositestv
      @easycompositestv  2 месяца назад +1

      Whilst you can cut a thread into carbon fibre, we don't recommend it as it will be very short lived. What would be a better option is to bond a threaded insert into the end of the tube which your bolt can then be screwed into. A roll wrapped tube would be better for this given that it has some reinforcing running around the circumference. This will help to prevent any 'breakout' of the insert if it was to be loaded on an angle.

    I am interested in piano tuning levers. The tubes are about 300mm long. Tensile, compression, and torsion is not important but bending and hoop strength are key. Very high hoop strength and very little bending. Most I see are roll/wrap about 18mm to 22mm OD but I have no idea what ID they have - probably 16mm and 20mm respectively. How does the hoop strength increase and bending descrese if I used instead of 18mm x 16mm I used smaller diameter but thicker wall, say, 16mm x 12mm. Do you have a video where you compare tube wall thickness - same OD but different ID's for hoop strength and bending comparison? Also, I know UHM carbon fiber roll/wrap has less bend but it is brittle and will break under very heavy bending (but still maybe ok for piano tuning lever use).
    My idea is to allow an optional Stainless Steel rod to be inserted inside the tube to add more weight and some strength. Some people like the lighter weight of carbon fiber levers, but some prefer a bit more weight to them because heavier levers are bit eaiser to home in on the tuning pin when your arms are used to heavier levers.
    Is there a chart for all this?

    • @easycompositestv
      @easycompositestv  10 месяцев назад

      Hi Paul, We don't have any further videos that directly address this, but for a tuning lever at 18-22mm O.D. Even a 1mm wall would be almost impossible to break by hand with a 300mm lever, I could imagine that going thicker with the wall might be needed to eliminate any flex as I would imagine that's important in that application. You could start with a 1mm wall and just add layers to the outside until you have the performance that you need, then you'll know exactly how many layers to use for the second one!

    Wonderfully informative video. I wonder if you could do a video on the stresses of sleeved (telescopic) tubes. I have read that one need an overlap of between one fifth and one quarter of the length of the unsupported arm. So if the unsupported arm is 80 cm one needs an overlap of between 16 and 20 cm. Is that correct?

    • @easycompositestv
      @easycompositestv  Год назад

      The optimum amount of overlap would depend on the amount of hoop strength in the tubes. The overlap is there to spread the 'burst' load where the inner tube is trying to split the outer tube. The only way to know for sure would be to set two tubes up with the anticipated load. Begin with more overlap than you need and then start edging out the inner tube until you get to the failure point. You might find that for your load you can get away with less overlap and therefore achieve a longer reach for a given amount/weight of tube.

      Many thanks for your reply. My “tube” will actually be a D-shaped section that I will build myself to fit around at D-section crossbeam for a 2-metre RC trimaran. I will probably over-engineer it since I don’t want to break it. But I might start with a long overlap and gradually reduce it until I feel that I am beginning to get some slop in the connection. Once again, thanks for your reply. If I was in the UK I would certainly patronize your store.

      Unlike a thermoplastic, composites like the tubes can not be heated and bent to to shape. To hold any kind of shape they need to be moulded in this manner, for larger diameter tubes this can be done with a multi part mould and internal vacuum bag however this isn't appropriate for such small diameters. The only option really would be to 3D print a dissolvable core and wrap it with a braided sleeve. Once cured the internal structure can be dissolved from the centre.

    I need carbon fiber tubes for a 3D printer. I am using plastic bushings for Igus. That is the same setup as Bambu Labs are using in their current printers. The issue is finding straight tubes with the accurate dimensions. It is not that carbon fiber does not work with bushings, as they do with plastic ones from for example Igus. Also, I would prefer a bit bigger diameter if possible. Preferably like 12mm maybe 16mm. I guess 8 or 10mm could work, but given the stress they are put under, 12mm seems prudent. Do you guys have anything I could use? Are yours straight? Is the OD accurate? I guess we are looking at something stranded?

There are many rod manufacturers that use these carbon fibers, but I would bet that less than 1% understand their practical (not theoretical) qualities.

      Carbon fibre can be extremely good for making lightweight high-pressure vessels, you'll see a lot of tanks (such as hydrogen tanks) made either from pull-wound carbon fibre, or from aluminium wrapped in carbon fibre. In fact, there's a clip of this process included in this video when we mention pulwinding as another type of tube construction method. In terms of the tubes on test here, the pultrusions and the roll-wrapped, they are both designed for longitudinal stiffness, not to resist internal pressure. With no 'hoop' fibres, the pultrusions would be terrible for internal pressure. The roll-wrapped tubes which do have hoop fibres would fair much better but could be made *much* better by increasing the amount of fibre in the hoop direction.

  • @stanislavdenysenko2007

    It is interesting to see how the elastic modulus behaves at small deformations.
    In theory, with different types of weaving, different fibers should “switch on” at different moments of deformation.
    I saw an emphasis on this in the discussion topic of bicycle frames.
    At low loads they are “soft” and comfortable, and at large loads they are harder so as not to steal the rider’s energy.
    At the same time, when used in delta 3d printers, we need maximum rigidity at low loads.
