So I've been working on producing a carbon fibre coffee cup for many years, I want it to be perfect and its almost there.  For the past 2 years I've had the project on the back burner having spent many thousands on equipment and tests.  But last week watching the How Its Made featuring the Bugatti Veyron, I saw how their carbon nose cone always comes out with voids in tights places and that these areas were repaired to produce a flawless finish.  That made me think my process might be good enough and I can finish my cup with a few repairs.

I follow ChrisR on this one... pouring hot beverages in an epoxy cup isn't always a good thing...if not postcured, put your cup in the oven at 80°C, remove it and you'll see you'll be able to bend it. It will also feel sticky and have some smell...proper postcure is the least you can do, use a high thermal resin is even better.
