Hello Curt Thompson About the trouble that you had with the vacuum bagging. If you used a linear carbon tape, did it have a white filmy binder on one side? If so the problem is that the material that it is made of will react to the epoxy and outgas,forming bubbles all along the area of the carbon strip. If you do the same bagging with carbon not having the binder, it will turn out without that problem. It,s all in the long learning process.
