Vacuum Bagging Demo Recap

Last Thursday, February 10th we hosted a demonstration at our facility to cover vacuum bagging techniques.
The event was very well attended, I don't think we've ever had so many cars in our parking lot and had to use the neighbors parking as well!

We did a wet-layup project and two infusion projects (more on the infusion below). For the wet layup project we did a small R/C speed boat hull out of carbon fiber and epoxy (picture above).

We did two infusion projects, one is the skateboard in the picture above and is the same skateboard in the videos in my two prior posts. We also infused a foam cored box to show that you can in fact infuse without having to have a mold.

The box is simply 1/2" Divinycell foam cut and glued into the shape of a box and then covered with fiberglass fabric, in this case we used 10 oz 0/90 knit. We cover the foam with the fabric using spray glue and wrapping it tightly, similar to wrapping a present. The glass is then covered very carefully with peel ply to prevent wrinkles over the peel ply is the resin flow media (the green mesh you see in the picture). We also fold spiral wrap into some peel ply and place it so that it stands about 6" above the lip of the box, this is the vacuum line and resin break. All of that gets wrapped in an over sized vacuum bag. Supports are placed inside the box to prevent it from distorting when vacuum is pulled. Then we pull vacuum and once we're sure we have a good seal we infuse the box.

Our next Vacuum Bagging Demo will be Novemeber 10th from 6-8pm here at our facility 11824 Watertank Rd, Burlington WA 98233 and it is free.
