Bike needs a shock mount. How? First thought: compression mold plates, bond to frame tube, layup composite over junction for strength. Mount design was, as with the other parts so far, quick and inaccurate simply for the purpose of testing the composite manufacturing process.
Mold design.
Printed mold.
Prep the carbon layup.
Mold was waxed with part-all mold wax.
Mix resin > wet out fabric > lay into mold > compress with wood blocks and C-clamps > de-mold.
Sanded edges:
This worked well enough. Molding was straight forward, and the part geometry was acceptable. Few bubbles in the corners, but can eliminate those with more care on real parts. The resulting part had too high a resin composition though. I need to be more careful planning the correct number of plys for the volume to be molded.
