Excellent job.

amazing result, such professional process without any sophisticated tools... (just half of chemical lab but that's a laminating video after all :D)

Nice video. I wonder if you positioning the resin outlet at the edge like resin inlet position, will the resin successfully cover all over the part?. Because in my opinion the resin will travel much easier and faster to cover all over the area if you put the inlet edge to edge.

Fantastic! Is there some sort of "spring void" @ flanges, around part to allow for some press down of part? Is that part of the air channel?

Matthieu i suggest you to try the '' Zip seal'n peel'' from Mulco to create the outer seal. I'm confident will work and peel off without damage.

Video et chaîne très intéressante. Je fais de la fibre depuis quelques années et je n'ai pas encore osé tenter la fibre. Le prix des fournitures est important et il vaut mieux éviter les ratés et avoir des clients motivés pour le surcoût fibre. Avec vos pièces vraiment très belles ça donne envie d'essayer.

Chouette à entendre ! Content d'entendre que tu aimes mes vidéos ! Bonne chance

i was thinking rather than using silicon adhesives you can use a small-diameter silicone hose or even make a strip of silicon rubber yourself and put it in the place you applied silicon adhesive i hope you get what i mean and it makes sense

Great video brother.. iam wondered seeing infusion through the fibre with out Infusion mesh.. once I tried and it was a failure.. have to try this method.. thanks for explaining all the details bro..❤️👍

Very informative! Thanks for sharing. But I have a question: What's the benefit of the RTM? Only that you don't need the vakkum bagging? The work for the mould is so crazy

@MatthieuLibeert

It has a much faster production cycle, If all parameters are set up well you could make a good amount of parts a day. It's also a bit more environmental friendly having less vacuum supply waste and more economical when producing higher volumes. The inner and outer good finish, has some added benefits as well if you want to produce parts that have to fit into each other for example.

Als je de buitenkant van de mal sterker maakt en vastbout, kun je de bak met epoxy onder druk zetten met perslucht. Met +1 bar achter het epoxy reservoir gaat het er een stuk makkelijker doorheen. :-) Met alleen vacuum krijg ik het er niet doorheen wanneer ik mijn mallen met weefsel gesloten heb.

Hey Mathieu, Wat gebruik je om het Carbon te snijden?

Is there a weight difference between the infused product and the rtm method?

Nice series about RTM! Where did you get that clamp you're using to stick the hose in the mixing cup (around 5:07)?

Hey Matt, I was wondering would there be a difference in the process if the part had vertical walls? Would you need to ensure that the molds have a bit of flex to them so that vacuum can be applied evenly across a wide range of angles?

@MatthieuLibeert

It's always better to have a bit of a draft on your edges but straight edjes work as well... But it makes it a bit harder to remove the part... Having a flexible mould is never a good idea as under vacuum before resin it might warp your mould making it even harder to remove the part

@@MatthieuLibeert I probably could have worded it better, but I meant flexible on one side, so that it can press onto the surface of the part, while the other holds the shape. Thanks for the reply though! :)

Hi Matthieu this is my first time commenting but I have seen a lot of your videos and I want to tell you that I really admire what you do and how you do it. I am doing infusion with reusable silicone membranes to make my parts and I would be interested to switch to RTM method (silicone is driving me crazy), there is one difference that I noticed more than the others: the inlet tube is on the flange while the outlet tube is on the center of the piece. Is this a rule in the RTM? Because I'm used to doing exactly the opposite with silicone bags. Thank you very much for your videos! Marco

@MatthieuLibeert

No, depends on part geometry, having an inlet running all the way around the part will have a faster infusion than from one point in the middle

Hey! Nice video. About your sticky silicone problem. Why do you use it in the first place? You already have gaskets even if it's not the best kind to use fir your application. The best is to use different type of gasket for the inside and the outside. If you want to improve your mold in that regard some solutions could be discussed if you need. Cheers!

@MatthieuLibeert

2 жыл бұрын

The gaskets still had some micro leaks and wanted to avoid at all cost that all resin would go into the vacuum perimeter that seals the mould, so the idea was to add some silicone that would then comform to the lower mould surface and would then be fixed to the upper gasket and mould but not to the lower mould... Looking for better specific gaskets now to avoid all of this and have a perfect seal in one go

@@MatthieuLibeert One of the sheapest way to have good seals is to use silicone tubing in 10 or 12 mm diameter minimum. The softer the better. You might want to have two row of them each time (it's not mandatory at all), but you must left enought space between them to deform. The assembly is way easier by placing a small piece of a smaller soft tube at the jonction with silicone adhesiv. An other solution is to use neopren leap gasket but it's for the outside only. Anyway your main mistake, as I see it, is to have cut your gasket in the corners, you might have large radius in corners and a gasket in one piece.

Matthieu, als ik het goed begrijp doe je dit alleen maar om de buitenkant strak te hebben MAAR ook de binnenkant. Gewoon vaqum trekken gaat ook maar dan heb je geen afgewerkte binnenkant. Of wat is de opzet van alles?

Goede binnen en buitenafwerking, minder afval aan vacuumzakken, peelply, infusion mesh. Goedkoper hierdoor en minder milieubelastend. Alsook kan je de opbouw van een stuk als deze in minder dan 5min doen en meteen Infuseren... Als je alle parameters goed afsteld kan je een 10 tal stukken per dag maken

Shouldn't make a difference, pinholes are mostly caused by the resins and the fibers not the mould

For carbon fiber products, this method is only suitable for making products with smaller sizes. This method is used more in fiberglass products.
