Carbon Fiber molding

We have worked out all the kinks in the carbon fiber molding of our Cahokia blades.
The blades are made with a 6.2 oz large checkerboard weave carbon cloth.
Initially we where having bubbles in the finished surface that required either rejecting the part or costly finish re-work time.  Our improvement came when we modified our vacuum form to pull the bagging film from above the part with no breather material.
It progressively clings to the part and does not trap air.

The parts spend little time in the vac because we still have Missouri summer weather.  We pop them free and set them in the sun to finish curing.  We will shortly get on the shaft mandril form.  That will be fun to figure out.

Stay tuned...
