Hello,
I am planning on doing an infusion of a 5’5” x 20” surfboard. The board itself is made out of xps foam. I plan on doing the whole thing at once. I’m a little worried about the foam twisting while under vacuum. I’m thinking my solution to this is to do a hand layup of carbon rails (basically just around the perimeter of the foam). In my mind this will prevent the foam from distorting while under vacuum.
The epoxy I’m using has a viscosity of 350 and a working life of 40 minutes. The working life is what I’m concerned about. My plan to combat this is to pull vacuum from the wide point on both rails. I will then have spiral tubing running the length of the board on the deck and bottom with a resin feed line in each. I have no idea if this is a good idea or not but with only 40 minutes working time, it makes sense to me.
As for the lay up, it’s an xps foam core followed by 4 oz E cloth fiberglass, 2mm lantor soric lrc, 4 oz E cloth, peel ply, then bag. There will be spots along the rails were there is no soric, these spots will have flow mesh on top of the peel ply. I made a diagram of what I’m planning.
This will be my first go with infusion. Am I on the right track or will my ideas not work? Any input is more than welcome.
Thanks.
