    Can you use pre-preg e-glass to make molds?

    • Easy Composites Ltd
      Easy Composites Ltd  Month ago

      In theory yes you can as long as you have a suitable surface layer pre-preg to give a good quality mould surface.

    is it possibe to use an FDM 3D printed mould with this material ? for example a mould made out of ASA Acrylonitrile styrene acrylate

    • Easy Composites Ltd
      Easy Composites Ltd  Month ago

      We haven't tried this specifically but I would have two concerns; one being any outgassing from a Styrene based material and secondly being whether the ASA has a suitable enough HDT to be able to work at the higher curing temperatures required to cure the PrePreg.

    if i want to make wings how you make it? the interior o wings can be empty to store gasoline or battery but not at cost of strenght.
    You offer service build my parts? like give you digital 3D and you make it in carbonfiber for me. will cost me a lot more than try to make it by my self and buy all that stuffs(vacum bags epoxy sand paper.etc...)?

    • Easy Composites Ltd
      Easy Composites Ltd  2 months ago

      Wings are made in exactly the same as the skin of a bonnet or similar sized panel. If it is likely to be too flexible then increase the number of layers of fabric to suit. We do not offer a custom fabrication service ourselves.

    I have a question can I use it on a motocross clutch cover which has a hard life so do I need more layers to make it stronger? (If yes how many)

    • Easy Composites Ltd
      Easy Composites Ltd  3 months ago

      In theory, yes, it should be possible - you would need to incorporate some of the fibres at +/-45 degrees as well as 0/90 to ensure you had uniform mechanical strength in each direction. As a starting point, I would recommend matching the thickness of the original part if made in metal - doing so will result in a lighter finished piece but with similar overall strength.

    • Easy Composites Ltd
      Easy Composites Ltd  3 months ago +1

      Yes you can use carbon for these parts either on its own or in combination with a core material to add stiffness. Be aware that if you have internal areas, carbon will reduce signal strength.

    Excellent demo. This is how you sell products. By making these great tutorials you mitigate any confusion or misguidance that may result in poor ratings from the ignorant.
    Currently i have no room to store this Prepreg in a freezer nor do i have space for a suitable oven. Knowing those requirements i wont end up buying something i cant store or use properly.
    In my case vacuum impregnation is the best option although a bit more involved. I already have a suitable vacuum pump. i just need a few other things to get started.

    • Easy Composites Ltd
      Easy Composites Ltd  4 months ago

      Glad you liked the tutorial, even if you've concluded that for you resin infusion will be a better fit. It is worth pointing out that although we state an 'out-life' of 30 days for our XC110 system, this is VERY much on the safe side and we have used material that's been out of the freezer for 2-3 months without any problems at all. Officially we'll stick with the 30 days figure but this is not a reactive system and so if you do want to experiment with prepregs without the ability to keep them frozen then you wouldn't have to worry too much about them being out for more than 30 days at ambient.

    I have two questions
    Can the carbon look nice finished when the mold side isn't the part we want to look at? How are we going to achieve nice quality finish in this situation?
    Second question is when do we need to use extra epoxy on the fibers?
    Also the weight of the new carbon part you made vs the old engine cover. Thanks!

      IN most parts of the world, it is not going to be hot enough nor hot for long enough to complete the full cure cycle.

  • Mark Deng
    Mark Deng 8 months ago

    Really solid presentation. two questions here:
    1. does industry also use the draping and prepreg procedures shown in this presentations? Since it seems to involve a lot of manual adjustment, large deviation may occur in large production.
    2. in your channel, carbon fiber composite is mostly manufactured for laminate which has excellent lateral mechanical property but weak along out of plane direction. do you guys also make bulk composite parts which have fiber direction not only in plane but also in out of plane direction? Thank you.

    • Easy Composites Ltd
      Easy Composites Ltd  8 months ago

      Higher volume parts may need slightly different process and tools, however there are plenty of business using these techniques and materials to make parts in smaller and medium volumes.

      You can make parts stronger in those direction by rotating the plies of the material in a lay up. For many non-structural parts, this is not necessary though.

    is it possible to use a laser cutter cnc machine to cut precious pieces out of the carbon fiber rolls?

    • Darth Avocado
      Darth Avocado 8 months ago

      @Easy Composites Ltd thank you

    • Easy Composites Ltd
      Easy Composites Ltd  8 months ago +3

      Most commercially used pre-preg CNC cutting machines use a drag knife to do the cutting. A laser cutter might be difficult to get clean results due to having to cut through the carbon, epoxy and backing films, all of which will likely need different settings to cut perfectly.

  • MuffinMan0521

    Why are you making a carbon fiber mould from a plastic mould and then making the production parts from the carbon fiber part instead of continuing to use the plastic mould over and over?

    • Easy Composites Ltd
      Easy Composites Ltd  9 months ago +1

      In this instance, the Epoxy Tooling Board used for the pattern could indeed be used as a mould but only for short production runs as with heat cycling, it would eventually degrade and you may lose accuracy after a number of uses. If a larger production run of items is required; the PrePreg will last significantly longer and maintain accuracy throughout its life cycle.

  • Rickard Carlsson

    Very nice and informative video!
    Q: Looks like you have very sharp corners/edges, what is the minimum corner radious you would recommend?

    • Easy Composites Ltd
      Easy Composites Ltd  9 months ago +2

      Yes, we did choose to make a component with some very tight radii in this video. Tight radii like those on this component do make the layup more difficult and also increase the chances of bridging or pin-holes/micro voiding on these corners so wherever possible they should be avoided, however in this video we wanted to show what is possible. I would suggest trying to avoid corners with a radius of less than 1mm but wherever possible, make them as large as the design allows.

    hi easy composites LTD then you placing part under vaccum what kind of pump is that it is the same like AC vacum pump?

    • Easy Composites Ltd

      It's not dissimilar from a vacuum pump that you might use to charge an air conditioning system.

    • Easy Composites Ltd

      That's right, 'pre-preg' means pre-impregnated with resin so the resin is already mixed and pressed (impregnated) into the fabric.

    does the high-temperature mold last longer then unimold on out of oven resin infusion?

    • Easy Composites Ltd
      Easy Composites Ltd  10 months ago +1

      Both have a hard mould finish so both are likely to have similar lifespan in terms of surface degradation. Of course the Uni-mould system is slightly easier to use and slightly cheaper to produce so for resin infusion only moulds is the preferred choice.

    • Easy Composites Ltd

      Ideally it needs to have PID temperature control to ensure it can maintain the proper cure cycle. Also needs a vacuum port into the oven so you can keep the bag under vacuum.

      A crock pot is unlikely to have the appropriate temperature control abilities nor even heating to cure pre-preg properly.

    What is a ten minute drop test?

    • Easy Composites Ltd
      Easy Composites Ltd  Year ago

      It is a leak test to look for a drop in vacuum. It is a sign of how good the quality of your bagging is. If the bag is leaky you need to find the leak and fix it, or rebag worst case. Ideally you want a perfectly leak free bag for the best results.

  • Sebastian Santilli

    I'm going to make a stupid question. I never used prepreg because I don't a freezer to keep the material. Is a really bad idea to use my freezer at home? I wonder if the food is going to be contaminated. Of course I will seal the bags with the prepreg very very well.

    • Easy Composites Ltd
      Easy Composites Ltd  Year ago

      Hi Sebastian, that's not a stupid question at all. If the prepreg is in sealed bags then I would say it would be fine to be in your domestic freezer, especially in small quantities. If you become a regular user of prepreg then of course you'd switch to a separate freezer but for small amounts occassionally I would not have any concerns at all. It's also worth pointing out that - especially with the XPREG XC110 you see used in this video - the out-life of the prepreg (i.e. how long it can spend out of the freezer) is actually extremely long, probably more like 6 months (although we state 6 weeks). We're starting to find out that users have no problems from prepreg that's been out of the freezer for several months and in fact the XPREG XC110 datasheet might soon be updated to reflect this.

    Thanks

    • Easy Composites Ltd
      Easy Composites Ltd  Year ago +4

      Creating a cored panel with pre-preg materials is commonly done to improve strength and stiffness so it is possible to do so. You need the right core material to withstand the cure temperatures and depending on the resin uptake of the core, you may need to use a film adhesive to add resin adhesive to bond them together properly.

      Easy Composites Ltd hmmm you just gave me a great idea. We run w70 oil and I have heat pads snap on made us to warm the pan and the oil before the first start up on a cold day. If I used my heat pad would I just use peal ply between it and the pre preg and vacuum bag the whole lot? We have a hospitality truck and trailer that has a big kitchen in side where I could keep the prepreg cool. What’s the longest shelf life stuff you have @ 60-70 degrees? Or does it always have to be kept in cooler temp? Thank you so much for the insight !

      Easy Composites Ltd if your ever at a drag race stop buy the snap on pit we would love to have you🏁thanks for the advice. There’s a lot of cars blowing the body off them then they pop the blower. And fixing body’s is becoming a regular occurrence

    • Easy Composites Ltd
      Easy Composites Ltd  Year ago +2

      Snap curing a prepreg in an emergency situation (like in the pit) can be done but you probably need moe control than simply a heat gun. If you could manufacture a patch (or jacket) that you could wrap around the prepreg repair which would generate a 120'C heat then you could cure off the right prepreg in 30-60 mins. You'd want to keep some consolidation pressure on it though (for example shrink-tape).
