It's called Coroplast and has an endless variety of uses, including RV underbellies.

Yup. I make large RC planes out of it also.
Gorilla Tape, aluminum rivits, or with some difficulty super glue (but absolutely permanent). With super glue the coroplast needs a very brief flame applied to both sides, then glued.
