Hello and greetings from Germany,
i've infused a test laminate on a glass plate to determine the infusion properties, weight and stiffness of the Soric core material, but i'm not satisfied with the result.





The thickness of the glassfibre at the edges is about 2,3 mm, where the skins of the sandwichcore composite have a weight of 624 g/m^2 on each site and a 2 mm Soric Core was used.
The used resin system provides a pot life of 210 minutes.
150 g resin + hardener were mixed and degassed under vacuum, so the infusion could be started.
The next 100 g portions of resins were mixed and left for 5 - 10 min on the table for degassing.
As a feed reservoir i used an angular placed glass pot, so that the following resin portions could be poured in slowly to avoid sucking air bubbles into the feed line.

I did not saw any air bubbles were pulled into the feed line and the vacuum pump was on over night.
1h after the infusion was completed, i've looked the last time at the laminate and the fiber and the channels in the soric were still fully impreagnated (clear appearance).
Now i'm a bit confused about the bad milky result.
Is it because i did not degassed the other resin portions under vacuum or is it because a did not set the braking zone properly in combination with the long pot life of the resin, so that too much resin was pulled out of the laminate?
