Can any one tell me what the max. thickness that can be infused at one time

Hi!
It depends on your resin specification, for ex. mine has max thickness of 12-15mm, check your own resin data. Also it depends on how big your part is. Mix max 2kg in one bucket at once, but then everything should be ok!

I have seen over 50mm infused (not done it myself but had it demonstrated) so as mentioned it depends on the resin viscosity but also the temperature, the stack resistance, the vacuum level, the flow medium and the inlet spacing you use.

If you can find an infusion resin with a viscosity of 350 mPa.s or less then you should be in the right ball park with a test or two, with a really thick laminate you may want to find one that has a mixed viscosity of 200 or less

As said it depends both on the material and the resin viscosity.

With our IN2Epoxy Infusion Resin  10mm is probably about as thick as you want to go with glass, especially if its a tighter plain weave as opposed to the looser twill weaves.


A point to note with all thick laminates is you need to slow the infusion down with a line clamp on the resin feed to allow the resin to soak through all the fabric layers.  If you let it whizz accross normally then you may well have pin holes, voids and dry patches.
