This episode covers how we wrapped raw carbon fibers immersed with epoxy around carbon tubes and then vacuum bagging them. One of our junctions used 10 feet of 50k carbon tow (roving) and the other used 20 feet of the same material. this time we used a slightly more viscous epoxy (hysol EA-9430) Not...
Part 4. More work on integrating the sub-frame into the aerodynamic fairing and the main drivetrain section. Using Freeman 1020 Low-Density Epoxy Molding Compound (aka...Cookie dough.) we got some very nice results but note, do not exceed the 1/2 inch thickness spec unless you have a really good way...
This 2nd video shows the result of the moldless vacuum bagging operation. The frame now weighs less than 2 pounds un-trimmed and now awaits a carbon fiber and aluminum head tube and aditional gussets and frame bits.
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 ...
