I haven't, but mainly because I don't have the necessary space/facilities to work with CF. I live in an apartment and don't really have space to make a CF-safe work zone (somewhere to contain the dust, keep my dog from eating the epoxy, etc). Ditto to a proper vacuum bagging setup [1]. I agree that CF is probably the ideal composite. I'm working mostly with wet-layup fiberglass cloth and sandwich panel constructions, as well as some semi-silly experiments with glue/paper/fiberglass. Also exploring some designs that use tension cables to support the load. Lots of fun, if not entirely fruitful so far [1] I could probably find space for a vacuum bagging setup...but my girlfriend barely tolerates all the stuff as it is. Best not to push my luck :)
