We are using a very interesting new material for Unfair’s interior. It’s called Airex C70.
AIREX® C70 is a lightweight, closed cell foam for universal use in sandwich constructions. Its excellent stiffness and strength to weight ratio and high toughness make it suitable for a large variety of applications. The foam is ideally suited for statically and dynamically loaded structures and is compatible to all resin systems.
Our friend and collaborator Guillermo (William) Fonseca of 1Off Rides is working on the interior panels using this awesome material. It can be fabricated as though it were MDF (the standard material for speaker boxes). It cuts fine with woodworking tools, and can be glued or screwed together to make complex shapes. Once the shapes are glued/screwed together and all the panels sanded/finished to fit, you can use ordinary fiberglass mesh and resin to make the shapes permanent.
