Does anyone know the details of Unifoil foil construction in terms of the core of front wings and rear wings? I hit my progression 13.5 and evolution 135 hard on reef and had some chunks taken out. Im wondering if its all solid carbon and epoxy inside or is there any foam core where water can absorb into and cause delam issues later on. Wondering if sanding smooth is enough or if I need to seal anything up with epoxy.
Thanks!
I cant speak to the exact carbon construction Unifoil uses. That being said, most modern carbon foils have a relatively small foam core, pre-preg carbon, and then carbon weave for appearance. If you can’t see the foam, I wouldn’t be worried about it. Sanding it smooth should do the trick. It’s possible the tail is solid carbon.
FWIW, I’ve had a few foils that leaked water (assuming to the core) and I’ve run them for years. I think the carbon is so thick (and therefore rigid) on foils there is no potential for delam - unlike a board where you might only have 1-2 layers of carbon, with a lot more foam volume.
In boards delam typically happens when water gets instead and evaporates in the sun, the vapor pressure causes the skin to separate from the foam. In a foil the volume of foam is so little relative to the carbon there is not much chance of this happening. Essentially Its easier to delam a high volume board because of this, which is why you typically see vent plugs on sups but not necessarily on prone boards.
