I am trying to perfect an RTM like process to create a foam core part. My piece is about 4 feet by 2 feet by 1 inch in size. I have a mold for the A side which has a ew compound curves and I am using plexiglass as the B side since the part is flat. My typical layup is a layer of 4 oz and a layer of 6 oz. I am really ting to dial in a process that eliminates the need for mesh and peel ply. I have tried a few runs using resin research infusion resin with medium length hardener 20 - 40 minutes). My problem is that it seems to take too long for the resin to infuse.
Are there any tricks to encouraging a faster infusion rate? I'm getting a 65% infusion off the part.
I can get a slower hardener but what other options are there?
Does the layup schedule matter? Do extra layers help the infusion?
I was thinking about inserting a layer of 2 oz polypropylene between or beneath the glass layers. I don't what to use soric. Would this work like an infusion mesh?
Can I cut grooves in the foam surface without affecting the finished surface? would this help distribute the resin faster?
How do I optimize the location of my vacuum and infusion ports relative to my mold?
Any advice would be much appreciated.

Maybe something like soric lrc or 3d pet core might solve your problem.
