Full material list will be added soon! when I find some time inbetween the composites work :D - Jak na to + styl
Love it. One of my favorite composite channels on CZcams.
Just a tip for those choosing to do what your doing but with mutiple curved surfaces. Over expanded cell Nomex honeycomb has strenght on the "X" axis and the ability to accept curves of "Y" axis(width of honeycomb) for boat hulls for example.
Congratulations on the work and presentation. I work with prepreg material for aerospace industry and I'm like so much of process. Well done guy !!!
I really loved
.....I watch you work several times / Congratulations
bro your work is amazing, i learn a lot, , thanks
glad you like it! thanks for the positive comment!
hi. the quality of your videos have greatly improved over time and I appreciate them.
question. what oven do you use?
Amazing tutorial! thanks alot! you mention about improving the mold, do you have any suggestion on what material/ method which can improve the mold quality?
Imagine doing this purely for a cosmetic docking station - this man owns funkopops, you just know it. I feel great shame on his families behalf.
Amazing work, please more videos like this! Actually im student of aeronautical engineer, and i want to know where this specific type of composite it's used, once again, thanks for share tour knowledge!
very nice presentation for mobile phone stand. Thank you so much.
Another great video, I just found your channel and really enjoy your work with composites. One question, sorry if it's a dumb one... If prepreg has the resin perfectly added, wouldn't adding something dry, like nomex, to it... I don't know... Throw it off a bit? Wouldn't it create a dry spot or something? Thank you.
Mold removal sound … priceless 😊
Great video!
What type of vaccum pump are you using?
It would be nice to see how stiff it is if you set some weights or books on it and show the flex.
What temperature do you need to cure it at?
Excellent work. My next project will be CNC machined aluminium mold for composites. Any ideas for aluminium coating? I wanted to use PTFE (teflon) anodising. Any experience with this types of molds?
Try some peel ply mate, it'll help with a few things. Nice video!
Very neat, would this still work for people that don't have an oven?
I need to get my hands om some 0.5mm with a slight bend in it, like in this video. I have some straight carbon plate but it just doesn't offer enough resistance when it's flat. Is there a way to induce a small permanent bend in carbon once it's cured? Otherwise, is it possible to make it yourself in such a thin configuration?
Hello. I use the same prepreg from easycomposites... Can you tell me the temperatures and the time you cure it? And if you remember the celcius per minute rate that increases when you first put your part in the oven?
can you use aluminum backing to a carbon fiber nomex honey comb sandwich for extra strength and in order to maintain the shape of the design where weight is not an issue
I miss working with prepreg! If your molds where thicker you would have gotten a better part. Since it was under vacuum it made the aluminum bend.
Brent Elliott thats correct :) but as this being a testpiece it was more than ok :p planned to do a flat piece first, then decide to give it a bend to make it more useful :)
Really beautiful video Mathieu,comme dhabitude.
how long was the curing cycle for this pre-preg?
+oTunis Thanks! must have been around 8 hours I think
wow that is one long curing cycle,i work for a company who sells pre-preg with a 20 min curing cycle at 120 degres.Send me an email at taha.yahyaoui@abccomposite.com if interested.
what temperature and how long in the oven?
hey man. Thanks alot for all of your videos. Can you go into further detail about how you got such a nice gloss finish with the clear coat. It looked kinda rough and then the video skipped to the part looking amazing and glossy. Thanks! keep it up
+TutShare simple 1K clear you can get in the DIY store and apply multiple coats...pretty basic :) no secrets here
+Matthieu Libeert (Mat's Prototyping) Thanks so much for a quick reply. I actually read this a while back but Im now in the middle of production and had a follow up question. There were a few holes in 7:22 and I'm wonder if you ONLY used clear coat to solve this or if you applied more layers or epoxy. Thanks so much. Your new videos this year are great!
easy composites non-autoclave pre-preg is ok at best if you want a smooth finish. It does the job if pin holes don't bother you. Which is what you saw is the pinholes.
Honeycomb A 1-80-3 ? what do you know about it? Young moduls, Poisson, Shear moduls?
What's the name of this music?? Please
Hi, Matthieu! Did you try to make prepregs your own?
DJKorzH Not yet will do this once I find some time
Did you put some mold release on the mold, or does it come off ok without?
release agent was used
thanks
Hi! What material you used, like honeycomb? Thank you, good job!
Artem, He used carbon fiber prepreg and honeycomb for this presentation. He did a good job.
Nomex honeycomb
How do you think it would stand up in a Rc car that gets repeatedly beaten. We use pure carbon fiber chassis but this looks lighter. Please let me know.
JAMMIN RC might work, but would be a complicated lay up with thos complicated 3D shapesin a RC car... second problem would be impact indeed...Those pieces are extremely rigid and strong but not sure if they behave well on short powerful impact
Have you seen the types of chassis we use. Mostly flat panels for our racing cars?
then might be possible, you could try it out
If you have any spare pieces can you make a strength test/destruction video?
would take me a bit to much time and to be honest I dont really have the tools to make a proper test
if you didnt use the breather layer what would have happened?
excess resin wouldnt be absorbed out of the part
u have a long way to go dear......
Aluminium is for the british english, Aluminum is for the american english. Btw, great tutorial bro, but, the curing proccess is only for the prepreg or even for the vacuum resin infusion???
What qualifies as "American English?"
"So, like, I saw this thing, like, with a thing and I was like, 'whoa, dude!'"
That about cover it? lol
Where did you learn how to do this
Feraud Quilens trial and error :)
How much is an oven like that? That seems very expensive.
That oven wasn't mine but must be around 2000euros
I have no idea what is the final destination of this composit part...
Does it matter? 😀
did you use heat gun of this process?
Ahmet Bal it was put in an oven at a controlled temperature
You can use a heat gun if the material is a tight weave. But hold it a minimum of 300mm from surface and heat slowly and evenly.
Be careful with low temp resin systems because they will start to cure if to much heat is added.
Where do you bay the prepress materials?
easycomposites.Co.uk

What do honeycomb cores do from a mechanical standpoint?
Add extra strength
@@MatthieuLibeert Does it save on having to use more layers of carbon?
Yes stronger and lighter
Resist compression and shear loads
One thing you have surely missed is making a normal or typical mold. Those pieces of aluminum can be only used for...... nothing with your project. Make a MOLD... and then you will have 200% better result.
I have many other videos online online à out that on my channel 😉, check some of my other videos!
man why not made something so corners not be visible ? i mean no holes from nomex..
Darius Dulskis is possible, but this as being a quick test and was not sure of the final dimensions I was able to use it was done this way. And to be honest I dont bother having the edges visible, this is more of a presentation piece and people can see whats inbetween :)
agree i see going to do more videos of wraping pieces i thought maybe to do same things to guys who search help :)
next video will be wrapping indeed, lot of questions about it :)
maybe im thinking to do wraping video or simply double side mold things and etc.
good idea
where can i buy honeycomb core?
I buy it from Easy Composites 🙂
@@MatthieuLibeert ty
back tail can be longer 4 better stability. imho
about video- finger up! molodetz!
Someday, somebody will come up with a cheaper, faster way to make Nomex honeycomb. Then, we'll all drive cars that weigh 500Kg and are indestructible.
It doesn't matter to me how you pronounce "aluminum." Just say it whichever way you choose. Anyone with a brain will know what you're talking about. It's one of those "if they care, they don't matter" issues. Only someone who's feeling a bit insecure about their own knowledge would knock you for using a different pronunciation of a word than they use, especially when all of Europe pronounces Aluminum as "Aluminium," and that's what everyone used to call it anyways.
Are you sure it is good like this?! I mean the whole think with vacuum is to reduce the amount of resin in it, right?! you basically build an 1 bar press..
Or did it still remove all the air out of the fiber...
Its pre-preg, you don't remove any of the resin, its at the perfect amount. Vacuum is to ensure all pieces bind without air bubbles as the resin heats up and flows.
+Kenneth James Finch sorry for questioning, at the place that I work we do this, I mean use the vacuum to reduce the resin even a bit more... As far as I know our labs studies reviled only the Gramms that where saved... (As far as I know)
Thank you for your answer! ;)
+Lux158 Is your lab using pre-preg or some sort of infusion process? or is the resin layed up by hand? each process will require different vacuum process
+Kenneth James Finch we do everything but i have asked about vacuumbagging in my company and they reply that it just take away the resin that was unnecessary, in prepreg;)
off cause the whole thinking of prepreg is to have the perfect ratio right away but as long as the company that makes them are controlled by humans they have their problems... also the things we built have, in some regions, 30 layers of prepreg or more, so that could easily add up..
surface quality horrible... a lot of pinhole...
yes thats what I explain in the videk, its because of the honeycomb
