Dave,
The idea in my application is to apply the inside laminate.
It does not matter if it goes off completely as the laminate is quite thin. All it does is prevent the inside from compressing which means the outside has to stretch more when curving the panel. A simplified description is this is bent around some frames.
If bent too much it will eventually crack as there is a limit to how much the outside will stretch before failure. This is why I had to do some testing - to ensure it can take the curve without problem. In my testing I used 8mm core cell foam and 200gm plain weave glass. The greatest curvature in the Razor hull is at the transom and it takes the curve quite easily.
You may ask why apply the inside laminate first. The fist laminate can be done on a flat table and I reason that it is just easier to apply a vacuum to the outside once the shape has been formed then to vacuum on the inside laminate.

If I find this to not be the case when prototyping the foam version I can go to an outside laminate option.
Replacing the 200gm plain weave glass with carbon would achieve exactly the same result. Now if you wanted significantly more curvature you would put the laminate on the outside.
Interesting side issue is that I have found that when a light laminate is put on the outside of 4mm gaboon ply I have managed to device a process that will allow me to bend bend it around a 40mm radius without failure and this is without steaming. I'm convinced that there is a great deal more flexibility in the materials that we have available to us than we are currently using. We just have to look for slightly different processes.

Phill
