Diolen (polyester fabric) instead of CF for body panels?

Just curious if anyone has used diolen isntead of carbon fiber for body panels? The panels would be wrapped or painted, so the cosmetic appearance is not very important. I do know that diolen has very good impact and abrasion resistance/strength... but the stiffness is not as good as Carbon or kevlar. 

The goal is to reduce weight, and also reduce cost (drastically in comparison to CF). I was thinking diolen could be used, and if stiffness was an issue then carbon fiber strips could be used as reinforcement. Something like soric would be used as the core... just because it makes bagging a lot easier IMO. Alternatively Carbon Fiber could be used as the skin, but again... reducing cost is important and I would prefer to not go this route unless absolutely needed.

I've not worked much with Diolen, but I do know it's pretty strong against impact.

Last option would be to use fiberglass to provide stiffness, but I'm not certain how this may affect the weight vs CF skin with Diolen... or even true CF build.

Any input would be appreciated. Thanks.

Diolen would be fine for this.  The stiffness would come from the panel thickness so a core layer would sort your rigidity.  Fluffy edges can be sanded from what I remember.  Its been a while since I did anything with diolen (canoes!).
