It looks like corrugated cardboard to me... I have some real thick cardboard sitting around in my room (looks similar to that material), and its actually pretty strong stuff. My father and I experimented with putting polyurethane on some, and it made it a good deal stiffer, too; cardboard's performance is nowhere near carbon fibre, fibreglass, Kevlar composites, etc, but it is surprisingly strong given its relative low cost and weight.
