Can someone explain how a resin brake works? the theory behind it and how to make it?

i've seen it mentioned on another forum.

I think the idea is to slow down the infusion process?

To be honest many people have there own definitions for a lot of composites terminology, These are the most likely:

Resin break (not brake) between the part and vacuum take off; this is an area between the vacuum distribution (mesh or spiral) and the part itself, the gap between does not contain any flow media mesh and is intended to slow the flow of resin so that the 'advance' of the resin will completly cover the part before getting to the vacuum distribution.

Resin brake (braking) to restrict the flow of resin into the part by partially closing the resin feed line with a clamp, this can help on thicker laminates to prevent the flow media side of the part advancing too far beyond the lower layers in the stack, which can lead to dry areas and pinholes.

If anyone else has any ideas for its meaning, or needs this, or some other terminology explaining, I look forward to hearing from you.

Yes I saw the need for resin flow manipulation yesterday. this Idea just dawned on me making my latest part. I had the infusion mesh on my part then up on the surface of the mold top. I need to notch the infusion mesh up on top so the resin is forced to flow through the part itself, not directly to the vacuum side.

 

Here's a Pic of What I mean, Next time I'll actuall make the cut. The resin did flow right but still coulda been better.
