How much CF is in each section? And can you give us a flex test?
so here is the layup
Twill Weave x1
5mm Thick pvc core
Twill weave x1
I will do a flex test when I come home, it has barely any flex to it.
there are two different types of layers in the deck, the ones that have a hole in the middle that slides right over the box on the mold, the second pieces are rectangles that just sit over the box with a slit at 45 degrees in the corners so that they can wrap down without any bulges. Let me know if i should do a drawing because i am very bad at explaining.
Is the PVC just for thickness?
no, the pvc stiffens up the board drastically while adding very minimal weight, without the pvc core the board would be very flexy and flimsy.
But PVC sheet bends in the hand…
Yes untill it is saturated with epoxy, after that it becomes very stiff.
I’m also curious about the choice of using pvc, can you post a link or tell us where you got it? Epoxy usuals doesn’t adhere well to pure untreated PVC. You used west system epoxy also?
Just so we are one the same page, I am talking about this type of core.
They guy who helped me with the layup designes misiles so I think he knows what he is talking about.
Thank you, I’m guessing Zach was thinking the same as me as pvc is a hard flexible plastic like acrylic, but it is a foam core pvc you used, very cool.
Yeah, see why you started to wonder. PVC foam cores are used very often in super light and strong carbon fiber parts. The lid on my board also has a tiny foam core inside, the plate that it was cut out of was supposed to be used for a missile but never ended up being used, got it from my dad:)
