Laminating two sheets of plywood with layer of Kevlar between

So, our poor OP is at a point and wondering why then kevlar canoes. I am too tired to post more..

 

I was thinking 4x8 panels.
This was just an idea that I wanted to find out if it was at all practical or even a good idea, which has been shown that it isn’t a good idea.

 

Lol I appreciate the advice and information!
I feel much more comfortable about just using 12mm without any fiberglass or Kevlar on inside.

 

I don't have experience of bonding 2 sheets of ply together but guess it would be better to use 2 sheets of 6mm rather than 4mm and 9mm for the issues previously raised.

 

Instead of dynel on the outside, you could use one the fabrics with a combination of fibers. They make fiberglass with carbon or kevlar, and also all three together. They combine properties of each.

 

on my 34' Wharram build of the late 70s I could easily have made one BIG improvement: save weight where possible instead of overbuilding...
