Hi,

I have been having trouble infusing a 9 mm thick basalt/vinylester laminate and have a few questions.

1. Should the flow media cover cover the entire laminate or should it only cover a part of it? Should it be in contact with the outlet spiral as well?
2. The flow on the top is much faster than at the bottom due to the flow media. Is there anything I can do to speed up the flow at the bottom surface?

Some help would be greatly appreciated.

Regards,

Tanmay

This ^

Also, if you're having problems with the resin moving through the top of the laminate too fast, use a hose clamp to restrict the hose a bit to slow the infusion. 9mm is pretty big, that should really be moving quite slow. How big is your laminate?

Use a slower infusion mesh, I've seen 25thk laminates successfully infused (although not tried it myself), it's all about matching the right speed infusion mesh, resin viscosity and gel time, stack sequence and dam length between the end of the mesh and the vacuum outlet to allow the bottom of the flow front to catch up with the top
