Infusing with PVC core

For leaks, you can double bag. The second bag is a pain but, it usually provides me with good insurance for leaks.

Thanks,

I used a stethoscope last time and that helped a lot but still did not get to a full seal. Frustrating!

Guys, I am brand new to resin infusion and had issues with my first attempt. Wandered if I could get some suggested fixes. I have read a lot and have some things to fix already. My approach was as follows. Flat part 28"x32", stack was pva, 1808 glass, 1/2" scored diving cell core, db 1700, peel ply, and bag. Ran resin line to center and teed into spiral that ran an 32" dimension. Vacuum lines ran on both long sides and only one short side. No flow media.

The top (1700) wet out almost 100% except couple spots on edges. Bottom was a disaster with lots of dry spots. Couple things I think Picked up here today. First my vacuum line touch the part and had no gap or break. I had a lot of resin flowing into vacuum lines. I think in need to add flow media on top of peel ply? Also I think I might try Vacuum lines on sides only? Because the 1808 has mat on it I was going to go with 1700 (no mat) on bottom as well.

Any other suggestions would be great.

I tried some experiments trying to sandwich CF with Divinycel H with exact same luck. I even went as far as perforating 1mm holes every 2cm on my 50x50cm test sheet.

I’d love to know how you succeed. I’m going back to stacked Coremat. At least that works at the price of a heavier part.
