CoreTough
CoreTough is a honeycombed truss-wing-formed composite wall sandwiched between a seamless, one-piece, thick outer facing and a thinner inner facing with no rivets required.
The CoreTough power structure starts with plastic sheet material like polyethylene, ABS, surlyn, polystyrene, or polycarbonate. The core material is then formed with Phelps Engineered Plastics proprietary CoreTough process which, through heat and convection, the core sheet is expanded to the desired honeycomb thickness and geometry. When mated with the specified facing, it becomes a material with a high degree of rigidity.
CoreTough is "pound for pound, lighter than aluminum and stronger than steel," and solves the four problems traditionally experienced with traditional aluminum sheet and post body construction: leakage, rust and corrosion, dents and dings, and weight management.
The lampshade shown above at the far right was designed by Jun Takagi and manufactured with CoreTough material. [Excerpted from the AR Haire website; suggested by Dana Rochex, Seattle.]
