Did you ever use carbon tracing paper to get a copy of a drawing you liked or needed? Well, I used carbon fiber and epoxy resin to sketch a 3d version (strong enough to sit on) of one of my favorite chairs. More than fifty years after Charles Eames made his Fiberglass DSR Chair, it's design and construction still stands, even in carbon because of his brilliant engineering job. The prototype can be seen at the Museum Boijmans Van Beuningen Rotterdam. Carbon copy will not be produced.
