[QUOTE=Thenorm;422771]carbon fibre is a very high performance material.
it has a very high stiffness to strength ratio. ideal for situations where weight savings is critical. (race cars, race bycicles, boeing 787). it is not a material for a casual user. fiberglass has many similar properties, just not as extreme.
Yes I been researching some and fiberglass is a really valid option. Cost wise its a no brainer. $6 a yard versus $40 a yard for carbon fiber.
Now if I used a fiberglass mat like this it seems it would be possible to use one layer of fiberglass on a 2 inch foam board and would be much more cost effective. Have a look at this thick matt and tell me if I am on the right track ok ?

I have worked with fiberglass a few times rebuilding a corvette fiberglass body so I have a good idea how it all works ! But never carbon fiber !
