Which is better for structural support PVC pipe or plywood?

[AamsterC2]

Ok hmm I suppose I could try making support for the ends that could be placed after the wings

Can you fix the construction to a wall ?

 

[AamsterC2]

No, I was planning on it to be mobile

KISS IS THE EQUATION- you can build a bow -archery type- out of pvc -good luck with plywood.

What I'm making is a long wing like structure for display, it will be about 10ft (3m) long and I'd like it to last a long time.

I'd be very reluctant to build anything from PVC if I wanted it to last a long time. PVC is a plastic type material and deforms plastically with the passage of time. Plywood has some of the same problems, but to a much lesser degree in most situations.
