Some cool ideas coming out simply by someone wanting to try somethung different, that's cool. I would email the info desk at Henkel, they have always really gone out of their way when i have had a question for them. They might have a VOC free option. I have always thought that VOC free epoxy had a ...

Hey guys I work quite a bit with entropy resins, and while I generally like their products a lot I would like to point out that it is still an epoxy and the source of the raw materials doesn't mean it's any better for your health. But with proper handling epoxies are really pretty safe to use and gl...

Weird thing is though.....the running length was affected more than the tips. I figured it would be the other way around as there is less wood thickness for glass to offset it the tips? This looks mint! and I actually really like the blodgynes :) Regarding the spoon - I would assume that the temper...

I strongly disagree with that and I know of a few cases where this lead to problems. You generally try to have a smooth transition in stiffness in order to avoid shear stress on the interface. So always core to biax to UD. If you want to have the UD against the core I would recommend putting a very...

So i quickly run a calculation in my calculation programm. This depends on the Layup and core so those values here are not 100% exact, but the difference is probably smaller than your production tolerances (no offense ;)) In general the stiffness is linear dependent of the ski width. So a 20% wider ...

The fiber volume content you get with a flax fabric depends hugely on the fabrics architecture. With the stitched biax or the uni fabric from bcomp the fiber volume ratio is quite good. It seems tho that you need a lot of resin as well, as the density of flax is so low. So a fabric with 350gsm is ju...

Hey guys I have to agree that colored resin to laminate the carbon fiber will not nearly be enough. I would paint the back of the topsheet with a white epoxy based paint. This worked really well for me in the past, but make some adhesion tests first. I had to press the skis while the paint was still...

Interesting point, I had made him the board for free, not even cost of materials. He had just split up with his Fiancée and I thought it might help him take his mind off things and move forward. The thanks you get eh HAHA. I'll still cut out the edge and repair it if he brings it around, mainly ju...

Yes with a thicker core the skis might have the stiffness, but with very thin composite face sheets the strength might be critical. Strength and stiffness are not related. Or not necessarily at least. But if you had good results with similar layups in the past then is all good! If it ain't broke don...
