This is not the blankets that I use, but are bacically the same. Mine are a self developed item, heating control is the hardest part of the development, that and insulation.

[FONT=Tahoma]I’ve always considered attempting this but was concerned that the blanked would introduce localized hot spots into the lay-up. Do you use anything in between the blanket and the panel?

I have to admit to using a regular electric blanket to aid curing during winter months. Works fine but would only get to 90F or so; good enough for my purposes…[/FONT]

How do you keep the fabric down in the corners and tight radis? I tried wet layup then vacuum bagging and couldn’t keep the fabric down even with a heavy epoxy resin.

So I just vacuum infuse.

Nice work Matvd, want to borrow my moulds???:slight_smile:

#25

Yes lol to make a car for me!

Hi Matt, Could you recommend a good 2k clearcoat. I’ve been using aerosols(Upol #1 Clear, being the best so far) but I would now like to start using a 2k clear.

#27

Any automotive 2k clearcoat would be fine. I will look at what the clearcoat that I have been using is. It is not an expensive clearcoat only cost about £25/litre.

#32

I messages you to see if you were interested in the hot binder remember?

#33

Messaged & hot bonder auto spell can really do a number sometimes lol

#34

Absolutley amazing work, especially from another brit :slight_smile:

We are infusing alot of our parts mainly down to the fact that we can reduce the amount of air bubbles found in the part.

Really interested in how you can produce this part as perfect as you do, without any airbubbles.

Please share :slight_smile:

Hi Matvd.
Your process:

  1. You wet lay up several plies of CF onto mould.
  2. You vacuum bag it (peel ply/perforated film/n4 breather/vacuum film)
  3. Vacuum it at 29"Hg (how long? @ 65C)
  4. Demould
    My question is, when you left the laminates under vacuum, didnt the part will have some pinholes since all resin will go up and catch by the n4 breather? how do you control the resin on the mould surface to prevent pinholes? Appreciate your advise.

There really is no secret to this, By letting the first layer b stage by the time the part goes into vac this will reduce the amount of pin holes that will be on the surface, however doing this requires extra care when vacuum baging the part as it can become easy to have large bridges in the corners that will ruin the part.
I am afraid that quality wet lay parts will only come from experience and practice.
