    When i say this is the greatest composite fiber channel on any platform, i genuinely mean it. The excruciating details are always covered but in the clearest and most concise way. You help us pleebs genuinely understand what we are hoping to achieve in addition to the step by step process. Dark aero is a worthy near-peer, but you are the man.

      @@easycompositestv/videos Its a very interesting topic and I like the fact that your company provides everything needed. However I would caution your not to try to rely too much on vendor lock-in. For instance, revealing the formula for the metal alloys wouldn't hurt since people are often more loyal to companies that are willing to share some of their recipes and you never know when someone might be able to tweak the recipe and make a better alloy. I know that businesses, for liability reasons, like to buy things off the shelf but all those businesses usually started from a common man indulging in a new hobby. Helping people get into the hobby on a low budget can create future customers very quickly. Maybe someone will invent something very useful while playing around.

    The older lost mandrel technique is using regular Styrofoam. Carve/mill the foam blank to your mandrel shape. Layup the fibre/resin in the regular fashion as if it was the permeant foam core. After the epoxy cures, you can use acetone to melt the Styrofoam mandrel.

This method is only an additional problem for craftsmen and confusion for small workshops. There are proven technologies that are better and simpler than the one invented and shown in this video.

      ​ @JetMax I did not express my thought correct.. when i say leaders, i mean they are leaders of info sphere among other composite manufacturers. Yes, there are bigger companies, such as Norpol, Scott Bader etc, but they provide just boring data sheets and technical documentation, while Easy Composites provides ideas and technologies that can be utilized with their materials. And they are leaders in that sphere. I learend many things by searching and reading a lot of uncomplete and fragmental tutorials before easy composites popped up, and since then there's no need to search for any tutorials, since EC have them all. And for me it is a big motivation to pay due and try their materials.

Not Light wt parts but strong. Now similar is done with blow molded abs! ( not as strong though)

    @g45h96 Год назад +1

    If I had to guess, the alloy is effectively a type of solder. Especially because I'd imagine the alloy needs to be eutectic to avoid deformation under pressure during the initial cure. And the usually low shrinkage of eutectic alloys is a plus.
    If this is the case, some neat things can be done, speaking from some experience doing stained glass.
    You can use the lead free alloy to make the initial madrels and components, and then use the lower melting point alloy with a soldering iron to correct surface mistakes and join parts. We used lower lead solders (higher melting points) to fill large gaps, and surfaced them with the regular 60-40 because it wouldn't melt the 63-37, allowing it to sit on top.

      12 years old now and still totally relevant) but the prices will change over the years. What we do instead is direct viewers to the project page on our website where we have even more information and a full list of materials used in the project. We can also use the project page to provide information that would otherwise go out of date in the video. If you ask a question on the project page on our site, it will always get answered 😀.

      Hey Marcus! We read all the comments, they mean a lot to us. Although we don’t have a physical base in the US, we can ship there direct from the UK. In fact, we’re currently sending hundreds of orders a week to the US. Shipping can be a bit more expensive (as you’d expect) but often quicker than US suppliers and our prices are generally lower too. And of course, we plan to open in the US one day too 😀.

    Great video. I would make a foam core for the wishbone, with some wire set into it. carbon fibre is brittle, so a bit risky for a safety component like a wishbone. The wire would (hopefully) stop it falling completely apart in a failure.
    ETA: I didn't realise it was for a recumbent cycle, so maybe reinforcement isn't necessary.

    • @bschwand
      @bschwand Год назад

      You do not need a cure oven. Only prepreg CF requires it, because of the type of epoxy resin.
      There are plenty of epoxy and polyester resins that are ambient temperature cure.

    • @easycompositestv
      @easycompositestv  Год назад

      You can indeed follow a similar process with hand laminating resins, although it would be important to use a resin that can take the temperature of the melt out. If you did use prepreg, it’s worth noting that you can use a conventional (domestic) oven for this process, you don’t need precision control and for the shrink wrapped version, you don’t even need a vacuum port into it.

    For the wishbone, what are the advantages of this process over just laying up the prepreg over the polyurethane model board pattern? The finished piece will be lighter by the weight of the pattern, but are there other differences/advantages?

    • @LupusMechanicus
      @LupusMechanicus Год назад

      Tubular objects don't really benefit from having a core is my guess. It would be tougher with the core, but if engineering design determines you don't need it then you don't need it.

    • @easycompositestv
      @easycompositestv  Год назад +1

      Pretty much as Lupus says, most components like this achieve a higher strength to weight ration by being hollow. A foam core of sufficient density to take a reasonable amount of consolidation pressure would weigh many grams and add little to the stiffness of the finished component. That said, there definitely are times when laminating around the outside of a core that’s left in is a good way to go. You need a core that can take prepreg curing temperatures, like Rohacell.

    • @mckenziekeith7434
      @mckenziekeith7434 Год назад +1

      Well, you would have to use a room temp cure epoxy if you use a wax mold. Unless you have a wax than can survive going through the curing oven at a temp that will harden the epoxy.

  • @Anton-zb9dc
    @Anton-zb9dc Год назад +2

    It would be beneficial to use silicon double sided press instead of vacuum bag for the best surface finish. Are there anything against this method, could you make video about using rubber membrane press for composites?

    • @easycompositestv
      @easycompositestv  Год назад +1

      Hi Anton, yes, you can do this. No real downsides providing the geometry of what you’re making allows relatively uniform pressure to be created across the whole surface; for example, a press will create pressure top and bottom but less pressure on the sides. You can mitigate this by restraining the silicone laterally but this takes a very strong construction (like a metal perimeter).
      We’ll definitely be doing some videos on silicone pressure moulding soon.

    As someone with only limited practical experience, I wonder why not continuous woven sleeve, for the simple part? Seems like it should both be easier to work with, and get better material properties and cosmetics? Or are the advantages of professionally infused prepreg hard to beat? Or is it that it would be harder to conform to such a geometry than I would imagine it would?

    • @newagetemplar6100
      @newagetemplar6100 Год назад +1

      As far as I know woven pre preg ‘ sock / sleeve ‘ is not available easily if at all . Probably due to it being less compliant when large changes in direction or diameter. Not to say there isn’t anyone out there manufacturing it .
      Secondly pre preg carbon fibre sock / sleeve would be harder to control resin ratio during the manufacturing process as pre preg resin is usually applied to woven carbon via a roller system and it also applies the protective film at the same time so it can be roles onto cardboard tubes .
      You would need an inner and outer protective film on sock / sleeve to stop the inner walls from sticking together while in manufacture and storage and that would not be practical .

      @newagetemplar6100 Год назад

      @@eelcohoogendoorn8044 yeah sorry , thought you were on the pre preg thinking mode .
      Yeah you could use a dry ‘sock’ and probably quite well , generally it will bridge between an inner radius . The sock will conform quite well as if you pull both ends it will naturally tighten around the mandrel then wrap with the release tape .
      May get a bit messy too but as you would have to melt the core out high temp resin would have to be used so it’s way easier to use pre preg .
      A solid wax core is an alternative using the same process if the end product is not subject to extreme temps .
      Again sorry for the confusion but hope this helps

    That metal is also a great way to bend tubing without getting deformation or kinks at the bends. It's especially useful for bending thin wall tubing to keep the tubing from collapsing. I just fill the tubing, bend it, then throw the tubes in a pot of water in an old stove in my shop. Heat it up and the metal comes right out, consolidating at the bottom of the pot and can be cooled and reused.

  • @CerberZer0S1gnaL
    @CerberZer0S1gnaL Год назад

    Very interesting method, but if you'd go with conventional fiber and vacuum bags you would probably be ok with simple high temperature wax, which coincidentally is printable, so no additional steps with casting is needed. However this is not suitable if you need to create a batch.
    Anyway I am very happy to see yet another one method of doing composite parts, you guys are awesome.

    • @easycompositestv
      @easycompositestv  Год назад

      Thanks and yes, you’re quite right that wax could be used for the mandrel in ambient temperature cure applications. It’s not suitable for prepregs and there are other drawbacks but used as you describe, if the wax could be printed then that would indeed be a nice quick workflow for the right project 👍.

    I have a new tool to help me create a carbon fibre inlet manifold for my ford Xflow 1600, namely a laser 3d scanner.
    The laser style scanner is able to scan down into holes, but I will still take a silicone mould of the actual port. To create 3d scan from.
    Lots of time has been spent flow testing and porting this manifold. So I’m keen to perfectly replicate the inlet port runner.
    Heck man, you should consider creating an episode covering a nice carbon fibre ITB four-banner inlet manifold.

    The aerospace industry uses eutectic salt mandrels for air ducting systems because the inner surface or I.M.L. (Inside Mould Line) is considered the 'A' surface because the noise level within the aircraft is reduced by having smooth smooth surfaces in contact with the ducted air.

      Indeed they do. We actually have some soluble salt compounds in our lab at the moment that we’re experimenting with. Generally, they’re harder to use without more industrial process equipment (like hydraulic presses and ultrasonic/high pressure cleaning) but if we can find a way to make them a bit more usable then we’ll feature those too in the future.
