moldless vacuum bagging carbon fiber bicycle frame

Using fillament wound carbon fiber tubing and prepreg carbon fiber plates as reinforcement gussets I was able to make a carbon fiber drivetrain chassis for a streamlined recumbent bicycle. We tacked the mitered tubes and gussets together with super glue on a granite surface plate to ensure perfect allignment and then wrapped them with woven carbon fiber tape and fabric that had been wet out with Loctite/Hysol E-120hp aerospace grade epoxy. Then using a welded aluminum frame with traditional bagging film, breather, peel ply on both sides we were able to achieve 30 inches of vacuum and held it for 12 hours. the next video in the series shows the part after curing.
